A gas at constant temperature is enclosed in a container with a movable piston. It occupies a space of 10L at a pressure of 500

torr. If the pressure is increased to 1200 torr, what is the new volume?

Answer:

4.17L

Explanation:

V1 = 10L

V2 =?

P1 = 500torr

P2 = 1200torr

Boyle's law states that at constant temperature, the volume of a gas is inversely proportional to its pressure.

P1V1 = P2V2

V2 = ( P1 * V1 ) / P2

V2 = 4.17L

The new volume of the gas is 4.17L

The normal boiling point of a liquid is 282 °C. At what temperature (in
ElenaW [278]

Answer:

The temperature at which the liquid vapor pressure will be 0.2 atm = 167.22 °C

Explanation:

Here we make use of the Clausius-Clapeyron equation;

ln\left (\frac{p_{2}}{p_{1}}  \right )=-\frac{\Delta H_{vap}}{R}\cdot \left (\frac{1}{T_{2}}-\frac{1}{T_{1}}  \right )

Where:

P₁ = 1 atm =The substance vapor pressure at temperature T₁ = 282°C = 555.15 K

P₂ = 0.2 atm = The substance vapor pressure at temperature T₂

\Delta H_{vap} = The heat of vaporization = 28.5 kJ/mol

R = The universal gas constant = 8.314 J/K·mol

Plugging in the above values in the Clausius-Clapeyron equation, we have;

ln\left (\frac{0.2}{1}  \right )=-\frac{28.5 \times 10^3}{8.3145}\cdot \left (\frac{1}{T_{2}}-\frac{1}{555.15}  \right )

\therefore T_2 = \frac{-3427.95}{ln(0.2)-6.175}

T₂ = 440.37 K

To convert to Celsius degree temperature, we subtract 273.15 as follows

T₂ in °C = 440.37 - 273.15 = 167.22 °C

Therefore, the temperature at which the liquid vapor pressure will be 0.2 atm = 167.22 °C.

Examine the reaction equation. CH4 + O2 →H2O + CO2 What coefficients will balance the equation? A) 2, 3, 2, 2 B) 1, 3, 2, 1 C) 1
kiruha [24]

Answer:

B

Explanation:

CH4 + O2 →H2O + CO2

Left side

C = 1

H = 4

O = 2

Right side

C = 1

H = 2

O = 3

So find common denominator in this case would be 6 O

CH4 + 3O2 →2H2O + CO2

Left side

C = 1

H = 4

O = 6

Right side

C = 1

H = 4

O = 6
