For this question, use the main assumptions of the kinetic molecular theory of gases:
1. gases are made up of molecules which are relatively far apart.
2. the molecules are in motion at high speeds.
3. the molecular collisions are perfectly elastic.
4. increase in temperature increases the kinetic energy of the molecules.
which of the assumptions explains the pressure which a gas exerts?
a.1
b.2
c.3
d.4
e.1 and 2
f.2 and 4

The actual answer is 3. The molecular collisions are perfectly elastic :))

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

the maximum mass of nh3 is nh3 in grams
