Hello!
The ball took up 2,9L
To solve this problem, we should apply the
ideal gas law and clear for n (the number of moles), as this value doesn't change when Devin takes the ball to the garage:

Now, we should clear this equation to find V2, as this is the value we are looking for:

≈2,9L
Have a nice day!
Answer: 55 g CaCl2 hope this helps
Here we have to choose the correct statement on the effect of temperature on the motion of the molecules and atoms of a gas.
As the temperature increases the molecules and atoms move faster.
As per the kinetic theory of gas molecules and atoms the kinetic energy (K.E.) of the atom or molecules is related to temperature by the equation
K.E. =
kT ( k = Boltzmann constant, T = temperature.
Thus as the temperature increases the K.E. increases thus the atom or molecules move faster.
With the decrease of temperature the movement of the atoms or molecules will be less and they will be near to each other.
The increment of temperature increase the K.E. thus the atoms or molecules move apart from each other.
With the decrease of temperature the movement of the atoms or molecules decreases.
The atoms of element
differ from each other based on the number of protons or electrons they have.
The number of protons or electrons is called the atomic number of an element
which serves as its original identity.
<span>Now, an isotope of an
element differs in their number of neutrons but the number of protons or
electrons are similar.</span>
