Answer:

RFM \: of \: methane \:  = 16 \: g \\ 16 \: g  \: are \: weighed \: by \: 1 \: mole \: of \: methane \\ 108.6 \: g \: are \: weighed \: by \: ( \frac{108.6}{16}  \times 1) \: moles \\  = 6.7875 \: moles \: of \: methane \\ from \: the \: equation :  \\ 1 \: mole \: of \: methane \: is \: formed \: by \: 2 \: moles \: of \: hydrogen \\ 6.7875 \: moles \: of \: methane \: will \: be \: produced \: by \: (6.7875 \times 2) \: moles \\  = 13.6 \: moles \: of \: hydrogen

Base your answers on the graph below, which represents uniform cooling of a sample of a pure substance, starting as a gas. Solid
Karolina [17]

Answer:

D & E

Explanation:

I think this is dealing with latent heat and D & E would be the range where you will find solid and liquid phases in equilibrium, cuz it starts as gas at from A to B, B to C is gas and liquid equilibrium, C to D is liquid, D to E solid and liquid, and then E to F is solid.

In a mixture of 2 ideal gases, A and B, PA = 0.2PB, what is the mole fraction of A?
Alborosie

Answer:

0.1667

Explanation:

Hello,

Dalton's law defines:

y_i=\frac{P_i}{P_T}

A total pressure is:

P_T=P_A+P_B

So, for A (solving for P_A in the previous equation, we get:

y_A=\frac{P_A}{P_A+P_B}

Since P_A=0.2P_B, we obtain:

y_A=\frac{P_A}{P_A+P_A/0.2}\\y_A=\frac{1}{6}\\y_A=0.1667}

Best regards.
