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.

a)

b) 1 mole of is produced.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The skeletal equation is:

The balanced equation will be:

Thus the coefficients are 2, 3 , 10 , 4 , 3 , 2 and 5.

b) Oxidation:

Reduction:

Net reaction:  

When 1 mole of is produced, 1 mole of is produced.
