HELP 10 PTS!!
the answers are given already but my teacher wants me to show work...pls help!!!

K I will attempt

Explanation:

a)

b)

1 : 2 : 2 (I don't know if this is what the question wants but it is what I would answer)

c)

Hydrogen because it requires 2 moles of H2 to react with 1 mole of O2

d)

24 moles of water. Look at stoichiometric coefficient. 2:2 means 24 moles you get 24 moles

e)

Oxygen. 2 < 5/2. Remember, 1 mole of O2 requires 2 moles of H2. But 5/2 is still greater than 2

f)

First, let's find out how many moles of water we can get. Since O2 is the limiting reactant, and O2:H2O ratio is 1:2, we will get 4 moles of H2O. Then, we can multiply 4 by Avogadro's number which is to get the number of molecules. We get: 2.41 * 10^24 molecules of water.

have a great day because if you dont you and i will be sad

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
