Answer:
By heating the solution
Explanation:
Physical changes and chemical changes are the two types of changes that a substance undergoes. Physical change does not alter the substance's chemical composition, hence, can be easily reversed. There is also no new product formed. This is contrary to the occurrences of a chemical change, which cannot be reversed after a new product has been formed.
A physical change is what occurs when Adrian's teacher dissolves some sugar in a beaker of water to form a sugar solution. This change does not involve any new product formation, hence, can be reversed. The sugar can be derived back from the solution by HEATING THE SOLUTION. The water (solvent) will evaporate and the sugar (solute) will precipitate.
Because the nuclear charge increases across a period and so it has a stronger pull on the outer electrons and will pull in the radius
.answer:
so the first one is analogous
the second is homologous
and the third is analogous
explanation:
analogous. this means they share a similar function (flight) but do not have the same embryonic origin.
