Answer:
Non of the option applies
Explanation:
Gases may be assumed to obey the ideal gas law, which states that, for pressure P, volume V, number of moles n, and temperature T,
PV = nRT.
where R is the gas constant, and n is the number of mole of gas
If the temperature is held constant, we obtain a simplified version called Boyle's Law, and if the pressure is held constant, we obtain Charles' Law.
Boyle's law:
Boyle's law states that the volume of a given mass of gas is inversely proportional to is pressure, provided that the temperature remains constant.
Mathematically,
P ∝ I/V
∴ PV ∝ 1
From the above mathematical expression, it shows that PV is a constant and does not change with pressure or volume.
∴ non of the options applies
Answer:
ion
Explanation:
An atom that has lost or gained an electron no longer has a neutral charge. We call this negatively or positively charged atom a(n) ________.
ion
Oxidation number is defined as the total number of electrons that are gained or lost by the atom to form a chemical bond.
the oxidation number of the compound H₂S is 0.
the sum of the oxidation numbers of the individual elements should add up to the oxidation number of the compound.
(oxidation number of H x 2 H ions) + oxidation number of S = 0
since we know the oxidation number of H, lets name the oxidation number of S = x
(+1 * 2 )+ (x) = 0
2 + x = 0
x = -2
oxidation number of S is -2
