<u>Answer:</u> The compound that has element ratio of 1 : 1 : 1 is KOH

<u>Explanation:</u>

Mole ratio is defined as the ratio of number of moles of the two elements combining to form a compound.

In a chemical compound, the subscripts represents the number of moles of elements in a compound.

For the given chemical reaction:

2K+2H_2O\rightarrow 2KOH+H_2

H_2O has two elements, hydrogen and oxygen and is present in the ratio of 2 : 1

KOH has three elements, potassium, hydrogen and oxygen and is present in the ratio of 1 : 1 : 1

Hence, the compound that has element ratio of 1 : 1 : 1 is KOH

Which statement best describes the amount of catalyst that remains at the end of a reaction?
Ivenika [448]
I believe the correct answer is C. The amount of catalyst is the same at the end as at the beginning of the reaction. Catalysts can't be consumed by the reaction thus is not D.
