c
1:1:2:1
d
2:1:1:1

Answer 1

To balance the chemical equations, we need to ensure that the number of elements on both sides of the equation is the same.

a: 1A + 2B + 1C + 1D → 2A + 2B + C + D

b: A + B + C + 2D → A + B + C + 2D

c: A + B + 2C + D → A + B + 2C + D

d: 2A + B + C + D → 2A + B + C + D
