Balancing Chemical Equations Practice

The video tutorial explains how to balance a chemical equation involving ammonia and carbonic acid to yield ammonium carbonate. It begins by counting the atoms on both the reactant and product sides of the equation. The instructor identifies the imbalance in nitrogen and hydrogen atoms and demonstrates how to adjust the coefficients to achieve a balanced equation. The tutorial concludes with a confirmation that the equation is balanced and a final review of the balanced equation.

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

• Three

• Five

• Eight

• Six

How many nitrogen atoms are present on the product side before balancing?

• One

• Two

• Three

• Four

What is the total number of hydrogen atoms on the product side before balancing?

• Eight

• Seven

• Six

• Five

What coefficient is used to balance the nitrogen atoms in the equation?

• One

• Three

• Four

• Two

After balancing, how many hydrogen atoms are there on each side of the equation?

• Five

• Six

• Seven

• Eight

What is the final balanced chemical equation?

• 2NH3 + CO2 → (NH4)2CO3

• NH3 + H2CO3 → NH4CO3

• 2NH3 + H2CO3 → (NH4)2CO3

• NH3 + CO2 → NH4CO3
