mass of Cl₂ = 8.61 grams
Explanation:
We have 2.75 of chlorine (Cl₂) which is gas. If we assume that it is behaving like an ideal gas and we work under standard conditions, we can use the following equation.
number of moles = volume / 22.4 (L / mole)
number of moles of Cl₂ = 2.75 / 22.4 = 0.123 moles
number of moles = mass / molecular weight
mass = number of moles × molecular weight
mass of Cl₂ = 0.123 × 71 = 8.61 grams

If you feel the answer is incorrect please comment and I will revise! Have a good day!
Proof:
2 minutes=250 meters
6 minutes=1,250 meters
7 minutes=1,600 meters
10 minutes= 1,600 meters
Answer:
.The concentration of N2O4(g) and the concentration of NO2(g) must be constant.
Explanation:
N2O4(g)<--------> 2NO2(g)
At equilibrium, all the concentrations of species involved in the equilibrium expression remain constant. This is because, at equilibrium, the rate of forward reaction equals the rate of reverse reaction. The concentration of the system does not change with time. The relative concentration of each specie, remain steady at equilibrium.
