metals donate electrons to nonsmetals
The solvent in the mixture is the ethyl alcohol assuming that the ethyl alcohol is not very dilute. The amount of the solvent must be greater than the amount of the solute. If the ethyl alcohol is dilute such that the resulting solution will have more water than pure ethyl alcohol, the solvent is water and the solute is ethyl alcohol.
Answer: Land absorbs heat energy and releases heat energy quickly. Water absorbs heat energy and releases heat energy slowly. Global convection currents are set up in the atmosphere because of the unequal heating of Earth's surfaces.
Density = mass/volume again, density is the ratio of mass to volume.
