What is a coefficient in a chemical equation?

In Chemistry the coefficient is the number in front of the formula.The

coefficient tells us how many molecules of a given formula are present.<h4

class=answerHeader>Explanation: Like Algebra the Coefficient is the

number in front of the variable terms. 4x^2y The coefficient is %4%In

Chemistry the coefficient is the number in front of the formula.

The

coefficient tells us how many molecules of a given formula are present.

2H_2O means we have 2 molecules of waterIn the balanced chemical

equation for Ammonia%N_2 + 3H_2 -> 2NH_3%We know we have coefficients of

1 for N_2

3 for H_2

and

2 for %NH_3%It takes 1

molecule of N_2 with 3 molecules of H_2 to produce 2 molecules of

NH_3
