Answer : The molar volume of the gas will be, 44.82 L
Solution :
Using ideal gas equation,

where,
n = number of moles of gas = 1 mole
P = pressure of the gas = 0.5 atm
T = temperature of the gas = 273 K
R = gas constant = 0.0821 Latm/moleK
V = volume of the gas.
Now put all the given values in the above equation, we get the molar volume of the gas.


Therefore, the molar volume of the gas will be, 44.82 L
The first one is B because it’s gonna be positive if it’s gaining energy
Explanation:
In chemistry, a salt is a chemical compound consisting of an ionic assembly of cations and anions.[1] Salts are composed of related numbers of cations (positively charged ions) and anions (negatively charged ions) so that the product is electrically neutral (without a net charge). These component ions can be inorganic, such as chloride (Cl−), or organic, such as acetate (CH
3CO−
2); and can be monatomic, such as fluoride (F−) or polyatomic, such as sulfate (SO2−
4).
