Cuco3(s) + 2hcl(aq) → cucl2(aq) + h2o(l) + co2(g). which statement correctly describes the substances in this reaction? a. exactly one product and two reactants are either liquid or dissolved in water. b. exactly one of the reactants is in a water-based solution, but none of the products are. c. the reactants include both a liquid and a gas. d. exactly one reactant is a solid, and exactly one product is a gas. e. the products include a solid, a liquid, and a gas.

So,

All you need to do is read the physical states ( ) to determine the answer.

CuCO3 is solid.

HCl is in aqueous solution.

CuCl2 is in aqueous solution.

H2O is liquid.

CO2 is gas.

It is then easy to see that option D is true.  CuCO3 is the solid reactant, and CO2 is the gas product.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
