Answer:
the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
Answer:
B. P (Phosphorus)
Explanation:
The element is be phosphorus.
This is true because phosphorus has a larger atomic radius than carbon. If you move than the group, elements gain additional electron shell. That additional electron shell keeps electrons far from the nucleus of the atom. This actually increases the atomic radius. Also, phosphorus is more electronegative than aluminum because phosphorus itself is a non-metal and non-metals are generally electronegative while aluminum is a metal and electropositive.
Phosphorus has a lower ionization energy than argon because the ionization energy across the period (i.e from left to right) increases and across period 3, you will find phosphorus first before argon in the periodic table.

2H2 (g) + O2 (g) -> 2H20 (g) + heat
It’s a combustion reaction
I can’t see the picture for some reason but if I were to guess, I would say Pangea.
