Science Question on Chemical Reactions
To balance the chemical equation, the values of the coefficients x, y, z, and t must be: Zn(NO₃)₂ → ZnO + NO₂ + O₂
A
4, 4, 2, 2
B
2, 4, 1, 4
C
2, 2, 4, 2
D
2, 2, 2, 4
Answer
2, 2, 4, 2
Explanation
Solution
Step 1: Balance Zn and NO₂. Step 2: Balance O₂. The balanced equation is Zn(NO₃)₂ → ZnO + NO₂ + O₂, with coefficients x=2, y=2, z=4, t=2.
