Question

What coefficient should be used to make the following equation balanced? N2+O2--> _NO

  1. 1
  2. 2
  3. 3
  4. 4

hintHint:

A balanced chemical equation is an equation in which the number of atoms of each element is equal on either side of the arrow. 

The correct answer is: 2


    2 should be used to make the following equation balanced. N2+O2 →_NO
    N2 + O2  → 2NO
    • A chemical equation can be balanced by following these four easy steps:
    • Write the unbalanced equation to demonstrate the reactants and products.
    • Determine how many atoms of each element there are on either side of the reaction arrow.
    • Coefficients (the numbers in front of the formulations) must be multiplied to equalize the number of atoms of each element on both sides of the equation.
    • Verify your work by stating the materials in which the reactants and products are composed.
