Question

7.Which set of coefficients correctly balances the following chemical equation?___H2SO4 + ___ LiOH Imported Asset ___ Li2SO4 + ___ H2O
A. 1, 1, 1, 1
B. 1, 2, 1, 1
C. 1, 2, 1, 2
D. 2, 4, 2, 2

Answer 1

H₂SO₄ + 2LiOH → Li₂SO₄ + 2H₂O

C. 1, 2, 1, 2 

Answer 2

Answer:

The answer is C.

Explanation:

First, we have to balance the amount of Li moles we have on one side and the other in the equation. We see that on the right side we have two moles of Li and on the left side we only have one. So we must multiply LiOH by 2 to have the same amount of moles on one side and the other.

Then we observe that S has only one mole on each side of the equation, so we can leave both molecules containing S with coefficient 1 and dedicate ourselves to evaluate the number of moles of the fourth compound.

If we multiply the molecule of H2O by 2, we equal the amount of H and O on both sides of the equation, so it would be balanced.

Have a nice day!
