Answer:
2000 mL
Explanation:
We have the following data:
Initial volume: V₁ = 1000 mL
Initial temperature: T₁ = -86°C + 273 = 187 K
Final temperature: T₂= 101°C + 273 = 374 K
According to Charles' law, as the temperature of a gas is increased at constant pressure, the volume is increased. That is expressed mathematically as:
V₁/T₁ = V₂/T₂
Thus, we calculate the final volume V₂ as follows:
V₂ = V₁/T₁ x T₂ = (1000 mL)/187 K x 374 K = 2000 mL
Therefore, the final volume is 2000 mL.
Wish I can help, but I don't take chemistry. :(

Answer:
D. ms=+1/2.
Explanation:
Hello there!
In this case, since the quantum numbers are known as:
* Principal quantum number (n) which cannot be zero. The allowed values of n are therefore 1, 2, 3, 4, and so on.
* Angular quantum number (l) is able to be any integer between 0 and n-1. If n = 2, for example, l can be either 0 or 1.
* Magnetic quantum number (m) is able to be any integer between -l and +l. If l = 3, m can be either -3, -2, -1, 0, +1, +2 or +3.
* Spin Quantum Number (ms): ms = +½ or -½. Accounts for the orientation of the spin axis of an electron as it is able to spin in only one of two directions.
Thus, since the fourth quantum number is ms, spin, we infer that the answer is D. ms=+1/2 because it represents the positive spin on 2s^2.

Answer:
A solution exhibits colligative properties since solute interferes with the interaction of the atoms which would change certain properties of the solution. It's the freezing point that is affected. Here's how we solve it:
ΔT = kf (m) i
where kf is the freezing point depression constant which is 1.86 for water
m= molality
i= the van't hoff factor which is 2 for NaCl
ΔT = 1.86(0.321) 2
ΔT = 1.19412 °C
1.19412 °C = 0 - T
T = -1.19412 °C
Round your answer with 3 decimal places, which is -1.194°C
Hope this helps and stay safe during these crucial we will get through this!
