Question

In the chemical equation: NO(g) + ½Cl2(g) → NOCl(g) How many moles of NOCl(g) are in the balanced chemical equation? fill in blank moles NOCl Report your answer as a whole number. Do NOT include units in your answer.

Answer 1

Answer: The coefficient of NOCl in the given balanced chemical equation is 1

Explanation:

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

Every balanced chemical equation follows law of conservation of mass

For the given balanced chemical equation:

$NO(g)+\frac{1}{2}Cl_2(g)\rightarrow NOCl(g)$

By Stroichiometry of the reaction:

1 mole of nitrogen monoxide gas reacts with $\frac{1}{2}$ moles of chlorine gas to produce 1 mole of NOCl

Hence, the coefficient of NOCl in the given balanced chemical equation is 1

Answer 2

Answer:

1

Explanation:

The numbers in front of the formulas (the coefficients) tell you how many moles of a substance are involved in a reaction.

If no coefficient is shown, we assume it is 1.

NOCl has no coefficient, so 1 mol of NOCl is in the balanced equation.
