Question

Balance chemical equation NaNO3 NaNO2+o2

Answer 1

Answer:

2 NaNO3 → 2 NaNO2 + O2

Explanation:

Write down the unbalanced equation: NaNO3 → NaNO2 + O2

• Count the number of atoms of each element on both sides of the equation. In this case, there are 1 Na, 1 N, and 3 O atoms on the left side, and 1 Na, 1 N, and 2 O atoms on the right side.
• To balance the equation, add a coefficient to each molecule as needed to equalize the number of atoms on both sides. In this case, you can add a coefficient of 2 in front of NaNO2 to balance the number of oxygen atoms on each side.
• The balanced equation is now: 2 NaNO3 → 2 NaNO2 + O2. This shows that two molecules of sodium nitrate decompose to form two molecules of sodium nitrite and one molecule of oxygen gas.
