Explanation:
Molar mass of Hg = 200.59g/mol.
Therefore Moles = Mass / Molar mass
= 100g / (200.59g/mol) = 0.499mol.

Probably that A has lost some electrons to B? This would be one reason for oxidization but this is a vague question. Hopes it helps
Answer:
Explanation:
The atomic number (Z) of copper is 29 and this isotope has an atomic mass (A) of 70.
The general symbol for an isotope E is .
The atomic number is a left subscript, and the atomic mass is a left superscript.
<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
Boyle's law states that pressure is inversely proportional to the volume of the gas at constant temperature.
Mathematically,
(At constant temperature)
Charles' law states that volume is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
(At constant pressure)
Gay-Lussac's law states that pressure is directly proportional to the temperature of the gas at constant volume.
Mathematically,
(At constant volume)
Hence, the correct answer is Option A.
