I want to try to grow algae in water with no CO2 input. I want to know if algae can grow if I only introduce elemental carbon instead of CO2. Coal is almost pure carbon, if I were to take coal dust and introduce that to my algae solution would it beneficial to the algae or have no effect?

No pure carbon. You would asphyxiate the plant. CO2 is what the algae take in their gas exchange process; just like we take in oxygen.

property (or high water-affinity) which titanium dioxide coating attracted water moist in the air to form an invisible film of water. This thin ...

I have a cool mist humidifier for my bedroom that i use at night. it suggests to use distilled water. if i use tap water dust like particles start accumulating all over my room. (on night stand, dressers, etc.)

Currently, i use purified drinking water (the PRIMO water) that you get from Lowes. but this gets expensive seeing that the humidifier chamber is rather large and uses alot of water daily. i went to my local grocery store and bought some 1 gallon bottles of distilled water. this too is expensive and time consuming. can i collect rainwater and use this in my "American Red Cross" cool mist humidifier? or do i need to process the rainwater through carbon or any other methods? collecting the water in a bucket and then dumping this into 1 gallon bottles would be the easiest and cheapest way, but is it the same, is is safe, and will it cause white dust particles to accumulate? thanks!!!

Rain water is not distilled. Even purified drinking water is not the same as distilled.

Correct me if I'm wrong, but it evaporates more than water because water stores extra energy in it's bonds right? Is that the only reason? Then why does gasoline rise above air if it is such a big molecule? Does it? Okay, if it doesn't then why does Carbon Tetrachloride, which is obviously heavier than most air rise to the ozone to deplete it? I know dust rises because it is big and catches wind like a kite. Is it the same reasoning?
Thankyou in advance!

Gasoline evaporates more easily because the hydrogen-hydrogen attraction (gasoline molecules basically present their hydrogens to the world) is not as strong as the polar interactions between water molecules. Gasoline is non-polar and water is polar. So, yes, water-water interactions take more energy to overcome - it takes a higher temp to evaporate or to boil water.

Gasoline is less dense mostly because C=12 and O=16. Most gasoline molecules have monomers of CH2 or CH while water is H2O. so the with O weighing 33% more than C and having a similar ratio of H, water weighs more.

Gasoline doesn't rise above air. In stagnent air, it stays low. The Electrical Code recognizes this in a number of ways - water heaters in garages must be elevated 18" (because people store gasoline and lawn mowers in garages), and the high-risk area around around a gasoline transfer point is much bigger at the ground than in the air). But air moves around tremendously inside of buildings and outside and that mixes all the gases.

Carbon Tet (CCL4) is very dense but is also mixed in the atmosphere by winds and updrafts.

Look at some cave research to get a good idea of just how mixed most all other air is. I've measured distinct layers of 8% CO2 laying just below atmospheric air in such an stagnent environment. The evaporation and dispersion of gasoline, etc in the air is all about convection, not pure diffusion which is very slow and can be be overcome by density differences (as in the separation of U-235 from U-238 in specialized equipment.

I need help indentifying various ways to reduce the forms of pollution that have been identified. Determine whcih approach would be most feasible in the community.

Water and Air Analysis of Home
Living in a small town where the major businesses are the local supermarket and the Dairy Queen restaurant, the people of Cooper, TX, may not believe there is a need to be concerned with pollution forms the water and air. Since this is a small town, there are limits to the type of monitoring of pollutants available. When people think of the word pollution, they associate it with chemical factories, manufacture companies, and waste management businesses. Pollution in the water and air can still exist in a community without the reality of these types of companies. With limited tracking methods for pollutants in this community, there are potential risks that the community needs to become aware of.
There are not any industrial companies, but farming is a chief source of income for the town. Smog and soot are not high factors for reducing the air quality of the town. “According to research conducted by Scoreboard.com, Cooper ranks amount the cleaner 30% of all counties in the United States in terms of pm-10 emissions” (Scoreboard.com ). Fugitive dust from road traffic and construction are the leading containments for decreasing air quality. In rural communities, while commercial waste management companies pick up trash on a weekly and bi-weekly basis, open burning of trash is very common. Wildfires and open trash burning represent half of the town’s air pollution sources. There have not been any harmful effects from air pollutants detected or linked to causing illness, diseases, or cancer. The economy is affected when open burning gets out of control and results in wildfires. There is only a volunteer fire department that consists of volunteers from surrounding communities in the county.
There are two different entities that provide water to the town. The local water company supplies people who live inside the city limits, and the county supplies water to the people who live outside of the city limits. Cooper uses rivers, streams, creeks, and lakes for water usage. Cooper also receives water from a watershed, Sulphur Headwaters, located in the county. (Scoreboard.com 1999) The Sulphur and South Sulphur River and the Big Creek Lake, two of Cooper’s water reservoirs, did not meet all requirements for certifying the safety of the water. The county is required to test the water for over 97 containments and notify the community in writing with an annual report. The report lists tests for lead and copper, total organic carbon, cryptosporidium, and coliform. “As of 2006, Turbidity was found as a result of soil runoff. While it does not have any health effects, it can disrupt disinfection and provide a medium for microbial growth that can cause nausea, cramps, diarrhea, and headaches.” (Delta County MUD 2006)
The community of Cooper may not have to worry themselves with smog in the air or stock up on bottle water, but they do need to be aware of potential effects from the air and water. Elderly, infants, cancer patients and others with immune problems are vulnerable to contaminants. By staying alert of the risks of water and air pollutants and how they are introduced into the atmosphere, will help to maintain a safe environment and decrease illnesses.

1 - The town/county or local water association can install a treatment plant to remove the Suspended solids from the water.

Otherwise, you, as either a business owner or homeowner would do well to install a carbon filtration system on the water coming into your home/business to remove said contaminants.

2 - The county can set aside some land for a commercial class 1 landfill to eliminate the burning of debris

Do you know the signifigance of water? Read it if you please:

What kinds of symptoms result from drinking too little water? Most commonly I see constipation, dry and itchy skin, acne, nose bleeds, repeated urinary tract infections, dry and unproductive coughs, constant sneezing, sinus pressure and headaches.

You might ask how a lack of water intake can cause this wide array of symptoms. Water is required by every cell in the body as nourishment and to remove wastes. When water becomes scarce, the body tries to limit the amount it loses through breathing, mucous production, urination, perspiration and bowel movements.

Several cups of water are lost daily through breathing because the lungs require humid air to do their work. In the winter when drier air prevails outside and heating systems (especially forced hot air and wood stoves) dry out the air inside, even more water is lost. It is estimated that on an average day in the fall, 3-4 cups of water are lost through breathing. On a cold, dry winter day as much as 2-3 more cups of water may be lost in this way. The body has to moisturize the air before it reaches the lungs and does so through the mucous membranes lining the nasal passages and the bronchi. As available fluid decreases, the mucous lining becomes drier. This in turn irritates the lungs, causing them to become more reactive to dust, mold particles, cigarette smoke and other irritants, and less resistant to viruses and bacteria. The result: dry cough and bronchitis.


The mucous membranes of our lungs and gut are an important component of our resistance to disease. They provide an effective barrier to bacteria, viruses and pollutants when intact. But a number of substances (such as aspirin) are known to harm this barrier. What is less well known is that a lack of water in the body makes the all important mucous less viscous and can cause constipation, irritable bowel syndrome and a slowed movement of the bowels contents. These problems in turn increase ones risk of other long term disease including hemorrhoids and colon cancer. The mucous lining in the sinus passages is similarly vital as a defense against disease. When it becomes drier, sinusitis, nose bleeds and allergic symptoms worsen.

Obviously, we all lose some water through urination and urination is required for the removal of various toxins from the body. When fluid volume is diminished, the ability of the body to remove toxins through urination is also diminished. It is a comon misunderstanding that the more water we drink, the harder it is on the kidneys. In fact, except for people with some uncommon kidney problems, the opposite is true. Water soluble toxins cannot be easily removed through the bowels, especially when a lack of water also causes constipation. These toxins then must be eliminated in other ways such as through the skin. The increase in body toxin levels can cause headaches and fatigue. The attempt by the body to remove excess levels of unwanted chemicals through the skin can cause acne and will aggravate eczema.

The easy solution to all these problems is to drink more water. Coffee, tea and soda all contain caffeine which is a known diuretic and will actually accentuate the symptoms of fluid loss. Fruit juices are more concentrated in sugar than your body's fluids and so the body will attempt to dilute them in the gut thereby causing a loss of water from other areas of the body. In the dry, hot air of winter and very hot days of summer, drink at least 10 glasses of water daily for optimal health. During the spring and fall, 8 glasses will suffice for most people, although those with inhalant allergies do best to drink as much water as possible. Pregnant women need to drink at least 50% more water daily than they would while not pregnant. People who exercise vigorously should add one glass of water for each 30 minutes of exercise. Herbal teas and diluted fruit juices (1/3 fruit juice to 2/3 water) can be substituted for some of the water. Drink one extra glass of water for each cup of coffee or black tea you have. Humidifying the air in the winter will help reduce water loss, but be careful to clean humidifiers daily to discourage bacteria or mold build up.

What type of water is best? Activated carbon or charcoal filtered water is probably the least expensive way to drink 'safe' water. The carbon filter removes most of the carcinogens and bacteria commonly found in drinking water. These filters are often very inexpensive and can be found in almost any department store. Distilled water has had all the metals (both harmful and helpful) removed. None of the flourinated and chlorinated hydrocarbons (coming from combining fertilizers and pesticides with flouride and chlorine) are removed. It is these hydrocarbons which are linked with the most health problems. Bottled spring waters may be healthy, but they are not yet required to be analyzed for chemical and bacterial levels.

Water can be a miracle cure for many common ailments. Try drinking some now and see if you don't feel better!

I definitly need to drink more water!
