Balancing Chemical Equations with Ions

The video tutorial explains how to balance the chemical equation AgNO3 + ZnSO4. It begins by introducing the equation and identifying the atoms and ions involved. The tutorial then demonstrates the process of balancing the equation by adjusting coefficients to ensure equal numbers of each type of atom on both sides. The video concludes with a summary of the balanced equation, emphasizing the importance of counting nitrate and sulfate ions as single units to simplify the balancing process.

• Three

Why can nitrate ions be counted as a single unit in this reaction?

• They are only present in the reactants.

• They remain intact during the reaction.

• They change into a different ion.

• They are not present in the products.

How many silver atoms are needed on the product side to balance the equation?

• One

• Two

• Three

• Four

What coefficient is placed in front of silver nitrate to balance the equation?

• Three

• Four

• Two

• One

What is the result of applying the coefficient to the nitrate ions in silver nitrate?

• Three nitrate ions

• Two nitrate ions

• One nitrate ion

• Four nitrate ions

How does treating ions as single units simplify the balancing process?

• It makes the equation more complex.

• It reduces the number of calculations.

• It eliminates the need for coefficients.

• It increases the number of steps.

What is the final balanced equation for silver nitrate and zinc sulfate?

• AgNO3 + ZnSO4 → Ag2SO4 + Zn(NO3)2

• 2AgNO3 + ZnSO4 → Ag2SO4 + Zn

• 2AgNO3 + ZnSO4 → Zn(NO3)2 + Ag2SO4

• AgNO3 + ZnSO4 → Zn + Ag2SO4
