Explanation:
The first involves keeping the surface of the concrete moist by the use ponding, spraying/sprinkling, damp sand or damp hessian.
The second prevents the loss of moisture from the concrete by covering it with polythene sheeting or leaving the formwork in place.
The third involves the use of spray or roller applied curing compounds.
Aluminium Carbonate on Dissociation produces Aluminium Ions and carbonate Ions as follow,
Al₂(CO₃)₃ → 2 Al⁺³ + 3 CO₃⁻²
Result:
On dissociation Al₂(CO₃)₃ produces FIVE Ions in total. The Ions produced and there number are as follow;
Al⁺² = 2
CO₃⁻² = 3

Since the volume of both the lead and the sand is 1.0-cm3, the exactly 1.0-cm3 of water is displaced in both cases.
<h3>How does the volumes compare?</h3>
The commonest way to measure the volume of a substance is by the displacement method. In this method, the substance is added into water and the volume of the water displaced is measured.
Let us note that the volume of water displaced is equal to the volume of the object. Since the volume of both the lead and the sand is 1.0-cm3, the exactly 1.0-cm3 of water is displaced in both cases.
