Question

determine whether the following equation is balanced- 2 na + 2 h₂o → 2 naoh + 1 h₂ the equation is not balanced because there are more oxygen atoms in the reactants than the products. the equation is not balanced because there are four atoms of hydrogen in the products and reactants. the equation is not balanced because there are more sodium atoms in the products than the reactants. the equation is balanced.

Explanation:

Step1: Count sodium (Na) atoms

Reactants: 2 Na. Products: 2 Na in 2 NaOH. So, 2 Na on both sides.

Step2: Count oxygen (O) atoms

Reactants: 2 O in 2 H₂O. Products: 2 O in 2 NaOH. So, 2 O on both sides.

Step3: Count hydrogen (H) atoms

Reactants: 4 H in 2 H₂O. Products: 2 H in 2 NaOH and 2 H in H₂, total 4 H.

Answer:

The equation is balanced.
