Moles Ca(OH)2 = 12.9 /74.092 g/mol=0.174 
<span>moles H3PO4 = 18.37/98.0 g/mol=0.187 </span>
<span>3 : 2 = x : 0.187 </span>
<span>x = moles Ca(OH)2 needed =0.281 </span>
<span>we have only 0.174 moles of calcium hydroxide so it is the limiting reactant </span>
<span>moles Ca3(PO4)2 = 0.174/3=0.0580 </span>
<span>mass = 0.0580 mol x 310.18 g/mol=18.0 g</span>

Answer:

The arm that was not sprayed with anything

Explanation:

The control group would be <u>the arm that was not sprayed with anything</u>.

<em>The control group during an experiment is a group that forms the baseline for comparison in other to determine the effects of a treatment. The control group does not include the variable that is being tested and as such, it provides the benchmark to measure the effects of the tested variable on the other group - the experimental group. In this case, the experimental group would be the arm that was sprayed with the repellent.</em>
