One of the best ways to scrub CO2 is with calcium and oxygen. Seawater has the biggest testament to this, as the ocean floor is completely covered in substances called calcium carbonates. This is the same mineral that small animals use to make seashells. It forms as a result of underwater volcanic eruptions, which spew thousands of tonnes of Co2 into the ocean. This is really the most efficient and effective way to get rid of CO2, as our oceans have been doing it for tens of thousands of years. If you counted up all the CO2 that's locked into calcium carbonates and released it into the atmosphere, our air would have more CO2 in it than Venus (which, as you know, has a runaway greenhouse effect resulting in temperatures of well over 1000 degrees). In fact, the only real difference between Earth and Venus in that respect is that Earth is 75% Ocean (on the surface). There are two power plants in the EU that are pumping their CO2 into a process similar to this. One pumps CO2 in liquid form straight underwater to the ocean floor, where it stays and slowly "dissolves" into seashells. The other one, in Germany, is pumping CO2 into the ground where they are hoping it will seep into saltwater aquifers and precipitate there.

What two things must be taken in by a plant for photosynthesis?
The two things that a plant takes in for photosynthesis are : light and carbon dioxide.
What would happen if water temperatures rise?
carbon dioxide could be absorbed
The atmospheric gas that forms a mild acid when dissolved in water is?
This would be carbon dioxide. When carbon dioxide dissolves in water (as all gases do to some extent) it forms carbonic acid, because the chemical formula would be in perfect balance. Carbonic acid has the chemical formula H2CO3. Also carbon dioxide dissolves into water more readily than many other atmospheric gases. CO2 + H2O <--> H2CO3
Why is carbonic acid important?
Carbon dioxide was first identified in the 1750s by Joseph Black, a Scottish chemist and physician. Carbon dioxide is a colouriess, odourless gas. It occurs in the atmospheres of many planets, including that of the earth. On the earth, all green plants must absorb carbon dioxide from the atmosphere to live and grow. Green plants convert carbon dioxide and water into food and oxygen. Plants and animals, in turn, "burn" the food by combining it with oxygen to release energy for growth and other life activities. This process, called respiration, is the reverse of photosynthesis. Oxygen is used up and carbon dioxide and water are used to produce more food and oxygen. The cycle of photosynthesis and respiration maintains the earth's natural balance of carbon dioxide and oxygen. Carbon dioxide is essential in the role of internal respiration. Internal respiration refers to the process by which oxygen'is transported to body tissues and carbon dioxide is carried away from them. This carbon dioxide is also a chief guardian of the pH of the blood, which is essential for survival. This buffer system - called the carbonate buffer - is made up of bicarbonate ion and dissolved carbon dioxide plus carbonic acid. The carbonic acid can neutralize hydroxide ions which, if added, would increase the pH of the blood and cause alkalosis. The bicarbonate ion can neutralize hydrogen ions which, if added, would cause a decrease in the pH of the blood and lead to acidosis. Both changes in pH are life threatening. The carbon dioxide in the earth's atmosphere helps regulate the planet's temperature. When sunlight reaches the earth, some of it is converted into heat. The carbon dioxide absorbs some of the heat and so helps keep it near the earth's surface. If all the heat from the sunlight escaped into outer space, the earth would become very cold. The amount of carbon dioxide in the atmosphere has been increasing since about 1890, chiefly as a result of the burning of fuels that contain carbon. This increase has caused a slight rise in the earth's average temperature. Carbon dioxide has important uses in the home and in industry. For example, carbon dioxide released by baking powder or yeast makes cake batter rise. Carbon dioxide in soft drinks, beer, and sparkling wines gives the beverages their fizz. Some fire extinguishers use carbon dioxide because it does not bum and because pure carbon dioxide is denser than air. Carbon dioxide's heaviness enables it to blanket a fire and prevent oxygen from getting to the fire thus starving the burning material of the oxygen it needs to continue burning. Dry ice is solid carbon dioxide. Carbon dioxide becomes a solid at -78.5 0C. The name dry ice refers to the fact that the substance changes from a solid to a gas without first becoming a liquid. Because of this property, dry ice is widely used in industry to refrigerate food, medicine, and other materials that would be damaged by the melting of ordinary ice. Carbon dioxide is one of the most important compounds on earth. Its importance to industry and the survival of all life are well documented. Without it, all human life would cease to exist. We all owe a debt of gratitude to our little friend CO2. That is why I believe the Chemistry Hall of Fame at York should adopt carbon dioxide into its halls, and give it the credit it well deserves
When an acid reacts with a carbonate what gas is given off?
its obvious..when an acid is reacting with a carbonate 3 things are made: Metal Salt Water Carbon Dioxide so the gas that would be given off is carbon dioxide
Would a forest fire affect the amount of carbon dioxide in the atmosphere?
Forest fires increase the amount of carbon dioxide in the atmosphere
How would a drastic reduction in plant life on earth affect the atmosphere?
levels of oxygen and carbon dioxide would decrease and levels of carbon dioxide would increase.
What would negatively affect carbon dioxide alveolar diffusion?
pulmonary edema
What is raw materials of photosynthesis?
6 CO2 + 6 H2O + light energy --> C6H12O6 + 6 O2. Carbon dioxide + water + light energy --> Glucose + Oxygen.
What colour would Carbon dioxide change limewater to?
Carbon dioxide.
How would you correctly punctuate Carbon dioxide?
Carbon dioxide (CO2) .
Does warm carbon dioxide rise faster than cold carbon dioxide?
In an atmosphere of carbon dioxide, warm carbon dioxide would rise. Since carbon dioxide is better than twice as dense as air, it would need to be really hot before it would rise.
Does carbonation have an affect on the growth of plants?
Generally, yes. Plants "breathe in" carbon dioxide and "breathe out" oxygen. Carbonation in water is suffused carbon dioxide, so we would expect that the extra CO2 would promote plant growth.
Where would carbon dioxide concentration be the highest?
The carbon dioxide concentration would be the highest where the oxygen is low.
If you were a plant that wanted to use sunlight to make glucose which set of additional rew materials would you require?
carbon dioxide and water
If you were a plant that wanted to use sunlight to make glucose which set of additional raw materials would you require?
Carbon dioxide and water.
Would waste materials such as carbon dioxide be removed from the person's body more quickly when he is running?
In the case of carbon dioxide, the person who is running is breathing is having to breathe much more often. Of course, this is important since the runner is making more carbon dioxide as a by product of using ATP for energy to run.
