Answer:
g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.
Explanation:
Sulfuric acid is represented as H₂SO₄ and calcium hydroxide is represented as Ca(OH)₂.
- To balance a chemical reaction. we should apply the law of conservation of mass that the no. of different atoms in both sides (reactants and products).
- The only choice that represent the reactants correctly and apply the law of conversation of mass is:
<em>g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.</em>
<em></em>
<em>f. H₂SO₄ + 2Ca(OH)₂ → 2CaSO₄ + 3H₂O </em>
is not correct that the no. of S, and O is not equal in both reaction sides.
S in reactants (1) while in products (2).
<em>O in reactants (8) while in products (11).</em>
<em></em>
<em>h. HSO₄ + CaOH → CaSO₄ + H₂O</em>
The reactants is represented in a wrong way.
<em> j. H₂SO₄+ Ca(OH)₂ → CaSO₄ + H₂O</em>
is not correct that the no. of H and O is not equal in both reaction sides.
H in reactants (4) while in products (2).
O in reactants (6) while in products (5).
<em></em>
<em>So, the right choice is: g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.</em>
