Answer: The specific heat of the Al is .
Explanation:
As we know that,
where,
= mass of water = 87.4 g
= mass of Al metal = 6.7797 g
= final temperature =
= temperature of water =
= temperature of Al metal =
= specific heat of water =
= specific heat of Al metal = ?
Now put all the given values in equation (1), we get
Therefore, the specific heat of the Al is .

C. As we know, an atom is made of three parts--protons (+), neutrons (core), and electrons (-) When one of these atoms loses one or more electron(s), it becomes a cation, or a positively charged ion. Inversely, when this atom gains a positively charged ion, [the atom] becomes a negatively charged atom, or an anion. The bond is made through electrostatic attraction, and a bond between these two "halves of a whole", it is known as an ionic bond.

Explanation:
The equilibrium vapor pressure of a liquid is the pressure exerted by a vapor on the liquid at a given temperature. It is measured in atm.
