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.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

the answer is minerals.
