Question

This formula equation is unbalanced. Pb(NO3)2(aq) + Li2SO4(aq)--> PbSO4(s) + LiNO3(aq). Which coefficient should appear in front of LiNO3 in the balanced equation?
1

2

3

4

Answer 1

Answer;

2

Explanation;

-On the left side of the equation, there are two Li and two NO3. Therefore, to balance the equation on the right, we should put a coefficient 2 , to have 2Li(NO3)

Pb(NO3)2(aq) + Li2SO4(aq)--> PbSO4(s) + 2LiNO3(aq).

-A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Chemical equation needs to be balanced so that it follows the law of conservation of mass.

Answer 2

2.
On the left side of the equation, there are two Li and two NO3. Therefore, the balanced equation on the right should be 2Li(NO3)
