Answer:
A
Explanation:
This is the only reaction where a element is displaced out of a solution and turn a soild, due to it been less reactive than the other causing its displacement The electrochemical series can be used as reference.

1 kilogram = 1,000 grams</h2><h2>

Since we are going from a larger unit to a smaller unit, we multiply.
So we multiply 1.25 by the conversion factor, which is 1,000.
This gives us 1,250 grams

Granite will be made up of the largest

See explanation
Explanation:
Atomic size increases down the group due to the addition of more shells.
As more shells are added and repulsion of inner electrons become more significant, atomic size increases down the group. However, across the period, atomic size decreases due to increase in effective nuclear charge without any increase in the number of shells. This causes increased attraction between the nucleus and the outermost shell thereby decreasing the size of the atom.
Ionization energy decreases down the group because the outermost electron is more shielded by inner electrons making it easier for this outermost electron to be lost. Across the period, ionization energy increases due to increase in effective nuclear charge which makes it more difficult to remove the outermost electron due to increased nuclear attraction.
