We first assume that the gas is an ideal gas so we can use the relation PV= nRT where P is the pressure, V is the volume, n is the number of moles R is the gas constant and T is the temperature. In a closed system, the number of moles should be constant since mass cannot be created or destroyed. So the only thing we can manipulate here is the volume of the system. We do as follows:
PV/T = nR = k
P1V1/T1 = P2V2/T2
V2 = P1V1T2/T1P2
V2 = 1.50 (298.15) V1 / (273.15)(1.0)
V2 = 1.64V1
Therefore, the volume should be changed by a factor of 1.64 of the original volume.
External fertilization in animals usually occurs in water or in damp areas in a process called spawning.

Explanation:
Lime is added to lower the acidity of lakes when pH levels go too low.
Acidic environment is harmful to aquatic ecosystems. Acidity causes some minerals, such as phosphorus and calcium, in the water to become unavailable to aquatic organisms like plants and fishes ( This means the water hardness is reduced). The low nutrients cause stress and death in the aquatic environment lowering biodiversity. Applying lime raises the pH to neutral levels and improves the health of the aquatic life in the lake. This also improves economic activities in the lake like fishing.

Answer:
J
Explanation:
Chlorine Gas is Cl2 so if it isnt on the left as that its wrong.
Then on the products see that Fe III means Fe is +3 charge so we have to have 3 Cl to balance it to 0 since each cl as -1 charge.
FInally check if the equation is balanced J is maybe H but its to blurry to tell
