Both are covalent compounds and in solid state they look like same solid water is wet ice and solid carbon dioxide is dry ice.
No. Elements in the same column of the Periodic Table have the same chemical properties. Oxygen and carbon are not.
Both carbon dioxide and hydrogen are gases at the temperatures and pressures found on the earth.
No, they don't.
hydrogen
The answer is carbon dioxide. It is considered to be a green house gas.
Fossil fuels are mainly made up from hydrogen and carbon atoms. When you burn them the oxygen in air chemically reacts with the hydrogen and carbon to produce carbon dioxide and water.
5 molecules of carbon dioxide will contain 5 carbon atoms (1 per molecule) and no hydrogen atoms as carbon dioxide contains only carbon and oxygen. The 5 molecules will contain a total of 10 oxygen atoms (2 per molecule).
Carbon dioxide and hydrogen sulfide
carbon dioxide is quite unreactive and used in fire extinguishers. Hydrogen burns readily with oxygen and is used as a rocket fuel.
How could it? There is no carbon in hydrogen. It order to make carbon dioxide, you must have carbon and oxygen.
Carbon dioxide is denser.
No, hydrogen, oxygen and carbon dioxide have very different weights.
A gas as carbon dioxide is easily expanded by heating; hydrogen peroxide is decomposed.
carbon dioxide is heavier than hydrogen because the molar mass of carbon dioxide (CO2) is 44 g/mol while hydrogen (H2) is 2 g/mol.
hydrogen
Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.
No. Hydrogen does not contain carbon, so no carbon dioxide is released just water and heat. See related link.
there is no hydrogen in carbon dioxide. since carbon dioxide is CO2 there are 3 carbon and 6 oxygen atoms in three molecules.
An organic compound must contain both carbon and hydrogen. Carbon dioxide and carbon monoxide contain carbon an oxygen, but not hydrogen.
Carbon dioxide, carbon monoxide, hydrogen.
