The student's lab manual says to mix some of his na2co3 solution with an aqueous solution of copper(ii) sulfate (cuso4)

write a balanced chemical equation to show the reaction. use state symbols.

Explanation:

When the student mixed the solution sodium carbonate with solution of copper(II) sulfate ; Copper Hydroxocarbonate , sodium sulfate and carbon dioxide gas was obtained as a products.

The balanced chemical reaction

Where:

= Copper(II) Hydroxocarbonate

= Sodium carbonate

= Copper(II) sulfate

= Sodium sulfate

= Carbon-dioxide

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)
