The equation shows the reaction between zinc metal and hydrochloric acid.

zn(s) + 2hcl(aq) mc014-1.jpg zncl2(aq) + h2(g)

what is the theoretical yield of hydrogen gas if 5.00 mol of zinc are added to an excess of hydrochloric acid?

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

i think its 5049.

i hope this !
