if four moles of sodium react, how many moles of chlorine gas will react?

Explanation:

The given chemical equation is as follows.

In order to balance the equation, the number of reactants must be equal to the number of products. So, when four moles of sodium reacts then the chemical equation will be as follows.

Thus, we can conclude that when four moles of sodium reacts then two moles of chlorine gas will react.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
