This is mind numbing, but I got you.
3NaOH + 1FeCl<em>3</em> = 1Fe(OH)<em>3 </em>+ 3NaCl
3Mg + 2H<em>3</em>(PO)<em>4</em> = 1Mg(PO<em>4</em>)<em>2</em> + 3H<em>2</em>
Proton—positive; electron<span>—negative; neutron—no charge. The charge on the proton and </span>electron<span> are the same size but opposite. The same number of protons and </span>electrons<span> exactly cancel one another in a neutral atom.</span>
From the experiment it can be concluded that a material or object which has a density that is lesser than water floats. Also, the object that has a density greater than that of water will sink. This is because density is the measure of the amount of substance that is occupied by an object in a given volume.
The solute is the part of the solution that dissolves in the second component (usually a fluid). Therefore, for the mentioned solution, the solute is ehyl alcohol since it is the one dissolving in water.
As for the solvent, it is the component in which the solute dissolves. In this case, it is water.
