Question:

Part A Balance the following equation:

K2CrO4+Na2SO3+HCl?KCl+Na2SO4+CrCl3+H2O

Generally coefficients of 1 are omitted from balanced chemical equations. When entering your answer, include coefficients of 1 as required for grading purposes.

Enter the coefficients for each compound, separated by commas, in the order in which they appear in the equation (e.g., 1,2,3,4,5,6,7).

..................

Part B

In the process of oxidizing I- to I2, SO42- is reduced to SO2. How many moles of SO2 are produced in the formation of one mole of I2?

Express your answer numerically in moles.

.............. mol

Balancing Chemical Equations:

A balanced chemical equation has always the same number of atoms per element on both sides of the equation. Balance first elements that appear only once in each side of the equation.
