Explanation:
You'll be using Gay-Lussac's Law for this. P1/T1=P2/T2
I have a class for this, and one of the practice questions was formatted this way, so I used that format and substituted said numbers as needed
P1:67 Pa
P2:60 Pa
T1:250 K
T2:?
I really hope this helps!
Answer:
7
Explanation:
sodium has 1 valence electron because of its place on the periodic table. a trick to use is included in the picture below to find out how many valence electrons an element has. to get from 1 to 8 we add 7.

Answer: As temperature increases, the number of collisions increases and the energy of the collisions increases.
Explanation:
According to collision theory, for a reaction to take place it is necessary to have collisions between the reacting species or atoms.
A collision will only be effective if species coming together have a certain minimum value of internal energy equal to the activation energy of the reaction.
More is the number of collisions taking place in a chemical reaction more will be the kinetic energy of its molecules. As kinetic energy is the energy acquired due to motion of atoms or a substance.
Also, collisions increases with increase in temperature as:
Kinetic energy is directly proportional to temperature. So, more is the temperature more will be energy of molecules.
Thus, we can conclude that as temperature increases, the number of collisions increases and the energy of the collisions increases.
