M of water = 2(1) + 16 = 18 g/mol
n of water = 24g/(18g/mol) = 4/3 mol
n of H2O : n of O2 = 2 : 1
2:1 = 4/3 : x
x = (4/3)/2 = 2/3 mol of O2
Answer:
D
Explanation:
--2 K (s) + __ H2SO3 (aq) --
-->
_K2SO3 (aq) + __H2
To balance this equation, all you need do is put a 2 in front of the K. The rest don't require any balancing coefficients.
Left
2 K
2 H
1 SO3
Right
K2
1 SO3
1 H2
It's balanced.
