Question

The equation given below shows an unbalanced chemical reaction between copper and silver nitrate.

Cu + p AgNO3 --- q (Ag) + Cu (NO3)2

What should be the value of p and q in the equation if matter is conserved during the reaction?
A.
p=2 q=2
B.
p=2 q=3
C.
p=3 q=2
D.
p=3 q=3

Answer 1

Answer: B

Two silver nitrates in left hands ide  would balance the two nitrates in copper nitrate

Answer 2

A. You have 1 NO3 and need 2 so you had 2 for P and for q you need 2 to balance Ag
