When calcium carbonate is added to hydrochloric acid, calcium chloride, carbon dioxide, and water are produced.
caco3 + 2hcl ⟶cacl2 + h2o + co2
a) how many grams of calcium chloride will be produced when 26.0g of calcium carbonate are combined whith 12.0g of hydrochloric acid?
b) which reactant is in excess and how many grams of this reactant will remain after the reaction is complete?

Elaborate on the reason(s) that matter is said to move even as in a solid state. select one: a. the particles are bound through intermolecular forces but are able to move past each other with relative freedom. b. the particles have sufficient energy to become an ionized gas and are in the most common state of matter in the universe. c. the particles are not able to move out of their positions relative to one another, but do have small vibrational movements. d. the particles are not bound to one another, move quickly, have a low density, and are able to spread apart from one another if unconstrained.
