To double the amount of sodium, you need to add the coefficient of

Explanation:

When we write a chemical equation then the number present in front of each element or compound is known as the coefficient.

For example,

Here, 2 present before Na represents that amount of sodium is twice the amount of chlorine which leads to the formation of 2 moles of sodium chloride salt.

Therefore, we can conclude that to double the amount of sodium, you need to add the coefficient of 2.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

answer: mole of the gas

answer: mole of the gasexplanation:
