Methane reacts with oxygen to produce carbon dioxide and water, what are the products? a. methane and water. b. oxygen and carbon dioxide. c. methane and oxygen. d. carbon dioxide and water.

 D. carbon dioxide and water.

Explanation:

Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.

The balanced chemical equation for combustion of methane is:

Reactants of a chemical reaction is defined as the substances which take part in a chemical reaction and undergoes a chemical change. Reactants are written on left side of the arrow.

Thus methane and oxygen are reactants of combustion reaction.

Products are defined as the substance which are formed at the end of the chemical reaction.Products are written on the right side of the arrow.

Thus carbon dioxide and water are products of combustion reaction.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

i think its 100.

hope this !
