Which sample of gas has the greatest average kinetic energy? O Ne at 312 K
O F2 at 275 K
He at 330 K
O O2 at 340 K
O Ar at 298 K
Question 2

He at 330K

Explanation:

This is because it has a high tempertature and is smaller which gives it a higher kenetic energy. It has a higher kenetic energy than O2 because of its size/bulkiness.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
