Balancing Chemical Equations and Ions

The video tutorial explains how to balance the chemical equation of barium hydroxide and carbonic acid. It begins by introducing the equation and counting the atoms on both the reactant and product sides. The tutorial emphasizes the importance of counting the carbonate ion as a single unit to simplify the balancing process. By adjusting the coefficients, the equation is balanced, ensuring equal numbers of each type of atom on both sides. The video concludes with a reminder of common mistakes and the final balanced equation.

What is the initial chemical equation discussed in the video?

• NaCl + H2O

• C6H12O6 + O2

• Ba(OH)2 + H2CO3

• H2O + CO2

How many hydrogen atoms are there on the reactant side before balancing?

• Four

• Two

• Three

• Five

What is the significance of the carbonate ion in the balancing process?

• It is ignored completely.

• It is counted as a single unit.

• It is split into carbon and oxygen.

• It is counted twice.

Why is it easier to balance the equation by treating the carbonate ion as one item?

• It reduces the number of atoms to count.

• It increases the number of atoms to count.

• It changes the chemical properties.

• It makes the equation unbalanced.

What adjustment is made to balance the hydrogen atoms on the product side?

• Add a coefficient of 1 to H2O

• Add a coefficient of 2 to H2O

• Add a coefficient of 4 to H2O

• Add a coefficient of 3 to H2O

What common mistake is highlighted in the video regarding hydrogen atoms?

• Counting hydrogen atoms as oxygen

• Counting hydrogen atoms separately

• Ignoring hydrogen atoms

• Counting hydrogen atoms twice

What is the final balanced equation for the reaction?

• Ba(OH)2 + H2CO3 → BaCO3 + H2

• Ba(OH)2 + H2CO3 → BaO + H2O

• Ba(OH)2 + H2CO3 → BaCO3 + H2O

• Ba(OH)2 + H2CO3 → BaCO3 + 2H2O
