Answer:

2.42x10^5 L

Explanation:

10.0ft x 11.0 ft x 8.00 ft = 880. ft^3 (1 cubic foot = 28316.8 cubic cm)

880. ft^3 * (28316.8 cubic cm/ 1 cubic foot) = 24,918,784 cm^3

(1L=103 cm^3)

24,918,784 cm^3 (1L/103 cm^3) = 2.42x10^5 L

Answer:

CH4 + 2O2 → CO2 + 2H2O Incomplete combustion – carbon monoxide and water. Ex. 2CH4 + 3O2 → 2CO + 4H2O The amount of oxygen present and the temperature determine whether the reaction is complete or incomplete.

A gas with a volume of 15L at 640K is cooled at a constant pressure until the volume reaches 5L. What is the new temperature?

Brut [27]

Answer:

The new temperature is 213.33 K

Explanation:

Charles's law indicates that the volume of gas at constant pressure is directly proportional to its temperature. This law indicates that if the temperature increases the volume increases and if the temperature decreases the volume decreases.

So, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:

$\frac{V}{T}=k$

When you want to study two different states, an initial and a final one of a gas, the expression can be applied:

$\frac{V1}{T1} =\frac{V2}{T2}$

In this case, you know:

V1= 15 L
T1= 640 K
V2= 5 L
T2=?

Replacing:

$\frac{15 L}{640 K} =\frac{5 L}{T2}$

Solving:

$T2=\frac{5 L}{\frac{15 L}{640 K} }=\frac{5 L*640 K}{15 L}$

T2= 213.33 K

<u><em>The new temperature is 213.33 K</em></u>
