Reactivity of Mg and Ca
Introduction
The aim of this practical is to observe the difference in the reactivity between Mg and Ca when hot and cold water is added.
Hypothesis
We think they will react in some kind of form.
Variables
The independent variable was the temperature of the water and also the quantity of metal use in the experiment and the dependent variable was the reaction.
Equipment
