C is the correct answer for this question. since it is a physical change
Answer:
No, gases move freely all over the place, liquids move more freely but in a more contained area, and solids the molecules are rigid, at the most the movement is small vibration as the molecules put pressure on one another to hold their form and stay in place.
False cause they give the truth in a disguise
Answer:
Mass = 30.104 g
Explanation:
Given data:
Volume of Cl₂ = 8.80 L
Pressure = 890 torr (890/760 = 1.17 atm)
Temperature = 23°C (23+273 = 296K)
Mass of chlorine = ?
Solution:
PV = nRT
n = PV/RT
n = 1.17 atm × 8.80 L / 0.0821 atm. L. k⁻¹.mol⁻¹ × 296K
n = 10.296 atm. L / 24.30 atm. L.mol⁻¹
n = 0.424 mol
Mass of chlorine:
Mass = number of moles × molar mass
Mass = 0.424 mol × 71 g/mol
Mass = 30.104 g
