Question

For the reaction VCl2 + Cl2 → VCl5, what are the reactants, products, and correct coefficients in the balanced equation?

Reactants: 2VCl2 and 3Cl2; product: 2VCl5
Reactants: 2VCl2 and 1Cl2; product: 2VCl5
Products: 1VCl2 and 2Cl2; reactant: 1VCl5
Products: 2VCl2 and 1Cl2; reactant: 2VCl5

Answer 1

2VCl2 + 3Cl2 -> 2VCl5

Reactants: 2VCl2 and 3Cl2

Product: 2VCl5

To balance the equation, set up a chart with the reactants and products on separate sides. On one side should be V - 1 and Cl - 4 with a line and on the right side should be V - 1 and Cl - 5.

The numbers correspond with the subscripts. To balance, use the biggest compound (VCl5) and multiply that by 2 in order to get an even number for both of 2 and 10. For the reactants, you now need to multiply to get corresponding amounts.

Hope this helps!
