Question

Predict the products of each of the following reactions and then balance the chemical equations.

a. 2Na + 2H₂O → 2NaOH + H₂
b. Zn + 2HCl → ZnCl₂ + H₂
c. Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O
d. 2K + 2H₂O → 2KOH + H₂

Answer 1

The products and balanced equations for the given reactions are: a. 2Na + 2H₂O → 2NaOH + H₂ b. Zn + 2HCl → ZnCl₂ + H₂ c. Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O d. 2K + 2H₂O → 2KOH + H₂

Step-by-step explanation:

a. The products of the reaction between 2Na and 2H₂O are 2NaOH and H₂. The balanced equation is 2Na + 2H₂O → 2NaOH + H₂.

b. The products of the reaction between Zn and 2HCl are ZnCl₂ and H₂. The balanced equation is Zn + 2HCl → ZnCl₂ + H₂.

c. The products of the reaction between Ca(OH)₂ and 2HNO₃ are Ca(NO₃)₂ and 2H₂O. The balanced equation is Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O.

d. The products of the reaction between 2K and 2H₂O are 2KOH and H₂. The balanced equation is 2K + 2H₂O → 2KOH + H₂.
