Answer:Its c
Explanation:
Let us use a double displacement reaction of Lead (II) Nitrate and Potassium Chromate to produce Lead (II) Chromate and Potassium Nitrate to practice balancing an equation.
We begin with the base equation provided in the question.Pb(NO3)2(aq)+K2CrO4(aq)→PbCrO4(s)+KNO3(aq)
Looking at the the atom inventory ReactantsPb=1NO3=2
K=2CrO4=1
Products
Pb=1
NO3=1
K=1
CrO4=1
We can see that the
Kand NO3
are imbalanced.
If we add a coefficient of 2 in front of the
KNO3
this will balance the equation.
Pb(NO3)2(aq)+K2CrO4(aq)→PbCrO4(s)+2KNO3(aq)
