Answer:

-0.01 M

Explanation:

Let's consider the following reaction.

A(aq) + 2 B(aq) ⇌ 2 C(aq)

We will make an ICE chart.

        A(aq) + 2 B(aq) ⇌ 2 C(aq)

I        0.10M    0.10M         0M

C        -x            -2x           +2x

E       0.10-x   0.10-2x         2x

According to the chart, the concentration of C at equilibrium is:

2x = 0.02

x = 0.01

The value in the change row for A is:

-x = -0.01 M
