Question
What coefficient should be used to make the following equation balanced? N2+O2--> _NO
- 1
- 2
- 3
- 4
Hint:
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.
