Question

Which set of balancing coefficients (in respective order) can be used to balance the

following reaction:
-- K (s) + __ H2SO3 (aq) --
-->
_K2SO3 (aq) + __H2
-
a) 1,2,2,1
b) 2.1.2.1
c) 1,2,1,2
d) 2,1,1,1

Answer 1

D

Step-by-step 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.
