Answer:
The person on the right will move backwards/to the right.
The reason is because the person on the left is pushing with more force than the person on the right
Given:
Diprotic weak acid H2A:
Ka1 = 3.2 x 10^-6
Ka2 = 6.1 x 10^-9.
Concentration = 0.0650 m
Balanced chemical equation:
H2A ===> 2H+ + A2-
0.0650 0 0
-x 2x x
------------------------------
0.065 - x 2x x
ka1 = 3.2 x 10^-6 = [2x]^2 * [x] / (0.065 - x)
solve for x and determine the concentration at equilibrium.

chemical reactions in the kitchen
Baking soda and vinegar create carbon dioxide. In both of these cases, a chemical reaction between a solid and liquid creates a new substance, a gas. Both yeast and baking soda can be used to create a gas.
