Question

1. Write the formula and then balance the following equation.
Copper (II) sulphate + Oxygen + Copper (II) oxide + Sulphur dioxide​

Answer 1

Answer:

cu2+ +so42_gives cuso4

Answer 2

Formula and balanced equation

Given:

Copper (II) sulfate + Oxygen ⇒ Copper (II) oxide + Sulphur dioxide​

To do:

Write the formula and balance the given equation.

Explanation:

• As the equation is given in word form it must be converted to chemical form to make it balanced.
• To do the conversions, the formula of the compound involved in the reaction must be written.
• Accordingly,y the formula of the reactants as well products are as follows:

Formula of the reactants:

Copper (II) sulfate - $CuSO_4$

Oxygen - $O_2$

Formula of the products:

Copper (II) oxide - CuO

Sulfur dioxide​ - $SO_2$

• Thus the balanced chemical equation for the given word equation is as follows:

$2CuSO_4 + O2\rightarrow 2CuO + 4SO_2$
