It's basically when a base and an acid of some kind, come together to make H2O or Water.
<span>Some
of the solutions exhibit
colligative properties. These properties depend on the amount of solute
dissolved in a solvent. For boiling point elevation, we calculate the increase in temperature by the equation:
</span><span>ΔT(boiling point) =
(Kb)mi
where Kb is a constant, m is the molality of the solution, i is the van't Hoff factor.
From the given data, we can easily calculate for i as follows:
</span>ΔT(boiling point) = (Kb)mi
103.45 - 100 = (0.512)3.90i
i = 1.73 <-------van't Hoff factor
Different Fossil organisms succeed one another to go up through the different rock layers in a definite and determinable order. Therefore, any time period can be recognized by its fossil content

Answer:
Option D and Option B
When comparing the two elements K and Ge , the more metallic element is_____K_____ based on periodic trends alone.
When comparing the two elements Sb and Pb , the more metallic element is_____Pb______ based on periodic
Explanation:
The metallic characteristic increases when we move down a column in a periodic table or when we move left in the row.
Potassium and Germanium are located on the same row, but germanium lies on the right side of potassium. Thus, potassium (K) is more metallic than Germanium (Ge)
While Lead (Pb) lies to left of Sb in the adjacent column and is also lies below Sb. Hence Pb is more metallic than Sb
