Complete and balance the molecular equation, including phases, for the reaction of aqueous copper(ii) chloride, cucl2, and aqueous potassium phosphate, k3po4.

The molecular equation is written below.

Explanation:

Every balanced chemical equation follows law of conservation of mass.

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

A molecular equation is the balanced chemical equation where the ionic compounds are expressed as molecules rather than constituent ions.

The chemical equation for the reaction of copper (II) chloride and potassium phosphate follows:

By Stoichiometry of the reaction:

3 moles of copper (II) chloride reacts with 2 moles of potassium phosphate to produce 1 mole of copper (II) phosphate and 6 moles of potassium chloride.

Hence, the molecular equation is written above.

- "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)."

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
