======================================

My explaination will be Carbon,the non-metal element that contains of 6electrons,2.4 .....the positive charge 4 valenced electrons will share its electron with 2 oxygen atoms that consists of 4 valenced electrons too,in order to achieve stable octet electron arrangement,thus CO2 is formed

What is formed as a waste product during respiration?

Carbon dioxide, which you exhale/breath out.


Do any plants produce as much carbon dioxide as humans?

No, it's the other way around. Plants intake Carbon dioxide and put out Oxygen. In the theory of how the world formed, this is how the atmosphere got to contain Oxygen, from plants spreading over the continents and producing Oxygen.


How is carbonic acid formed?

Carbonic acid (H2CO3) is formed when carbon dioxide is dissolved in water under pressure. But carbonic acid is unstable, and under atmospheric pressure, decomposes to water and carbon dioxide. H2O + CO2 ---> H2CO3


What is formed when an acid reacts with a carbonate?

Carbon DioxideWhen an acid reacts with a carbonate, the products are:A salt + carbon dioxide + water


When fuels burn which gas is formed and why?

When fuels burn, a combustion reaction is observed. This means that the fuel, which is made predominantly from carbon and hydrogen is heated in the presence of oxygen. If there is sufficient oxygen, you will have carbon dioxide and water produced. This is called complete combustion. When there is insufficient amounts of oxygen, the fuel cannot burn to completion, so you will get carbon dioxide, carbon, and/or carbon monoxide; and of course, water. This is called incomplete combustion. So to sum up your answer, when burnt with enough oxygen present, the gas that is formed will be carbon dioxide. If there is insufficient oxygen, then you will get carbon dioxide and carbon monoxide. Carbon is not included as it is a solid, not a gas. This is a chemical change and it happens because the reactants (fuel and oxygen) become excited when reacted with each other and the atoms rearrange themselves to form a new product.
