The answer is true. That is because once the object is in motion it doesn't want to change unless the object is forced to do so.

Luda [366]

Answer:

0.128 atm

Explanation:

There is some info missing. I think this is the original question.

<em>A reaction between liquid reactants takes place at -11.0 °C in a sealed, evacuated vessel with a measured volume of 45.0 L. Measurements show that the reaction produced 35.0 g of chlorine pentafluoride gas. Calculate the pressure of chlorine pentafluoride gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Round your answer to 3 significant digits.</em>

Step 1: Calculate the moles corresponding to 35.0 g of chlorine pentafluoride gas

The molar mass of chlorine pentafluoride gas is 130.44 g/mol. The moles corresponding to 35.0 g of chlorine pentafluoride gas are:

$35.0g \times \frac{1mol}{130.44g} = 0.268 mol$

Step 2: Convert the temperature to Kelvin

We will use the following expression.

K = °C + 273.15

K = -11.0°C + 273.15

K = 262.2 K

Step 3: Calculate the pressure of chlorine pentafluoride gas in the reaction vessel after the reaction

We will use the ideal gas equation.

$P \times V = n \times R \times T\\P = \frac{n \times R \times T}{V} = \frac{0.268mol \times \frac{0.0821atm.L}{mol.K} \times 262.2}{45.0L} = 0.128 atm$
