Balancing Chemical Equations Concepts

The video tutorial demonstrates how to balance the chemical equation of sodium carbonate reacting with nitric acid. It begins by counting the atoms on each side of the equation, focusing on sodium, nitrate, and carbonate ions. The tutorial then guides through balancing sodium and nitrate ions by adjusting coefficients. Finally, it completes the balancing process by ensuring all atoms are balanced, resulting in a balanced chemical equation.

What is the initial number of sodium atoms on the reactant side of the equation?

• Three

• Four

• Two

• One

Why is the nitrate ion treated as a single unit during the balancing process?

• It is a stable compound.

• It does not change during the reaction.

• It is easier to count.

• It is a common practice.

How many oxygen atoms are there on the product side before balancing?

• Four

• Three

• Two
