CO2
H-2O
The small volume of CO2 produced from airplanes is not likely an issue. Nothing can actually be done about this byproduct of flying, short of stopping that plane from flying.
In short, it is used in the Calvin-cycle to reduce CO2 into a sugar.
CO2, (note 2 is subscript and denotes that there is 2 oxygen atoms in the molecule.)
CO2 laser skin resurfacing involves using short concentrated bursts of light to precisely remove irregular layers of skin. Another name is Laser peel.
O=C=O carbon dioxide
Walking does not produce co2, apart from breathing. We inhale air and exhale CO2. The more effort, the greater the heart rate, the higher the co2 figure. However, this is part of the natural carbon cycle. The carbon dioxide we exhale was removed from the atmosphere a short time before, when the food we eat was grown. If your question is to compare walking with driving, walking is far better for the environment.
CO2 is a normal byproduct of human life. Our bodies use oxygen to create energy during aerobic activity (with oxygen) and then our bodies produce CO2 due to this activity. The blood takes the CO2 from our cells to the lungs, and then while the blood is picking up more oxygen, it dumps the CO2 so we can exhale it. Since we exhale CO2 with every breath the gas itself does not cause harm to the structure of the lung. However, we cannot sustain human life without taking in oxygen and breathing out the resulting CO2. If we were to inhale CO2, we would deprive our bodies of the necessary oxygen and in a short period of time would pass-out. Continued breathing of CO2 would eventually cause respiratory and/or cardiac failure.
co2
No. CO2 is a covalent compound.
the short answer is Yes...2HCI + CaCO3 becomes CACL2 + H2CO3 the H2CO3 decomposes to water and CO2
