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

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!

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
