Assume the imaginary metal, M, forms an cation with a +1 charge, M+. Add the formulas of the two products in the acid-base neutralization reaction below.

Question

The formula of the salt formed should go in the very last blank on the right. Balance the equation by typing in the smallest whole-number coefficients that would balance the equation in front of each reactant and product formula. Normally, a coefficient of one is not shown, but here you must type a 1 if there is only one.

____ H2SO3 + _____ MOH → _____ _______ + ______ _____

Answer 1

First write the unbalanced equation:

H2SO3 + MOH → M2SO3 + H2O

Note the most common reaction for these reactants is the formation of water

Then balance the M

H2SO3 + 2MOH → M2SO3 + H2O

Balance the SO3 as a group. It is balanced

Check H: 4 on left, 2 on the right. Balance with water.

H2SO3 + 2MOH → M2SO3 + 2H2O

Check O. 5 on the left, 5 on the right

Check M. 2 left, 2 right

Check H. 4 left, 4 right

Check S. 1 left, 1 right

All balanced.
