1 molecule of C3H7O has 7 atoms of hydrogen (remember that the numbers to the right of each symbol ara subscripts and they indicate the number of atoms of that element in the molecular formula).
Then 5 molecules will have 5 * 7 atoms of hydrogen.
5 * 7 = 35.
Then the answer is that there are 35 atoms of hydrogen in 5 molecules of isopropyl alcohol, C3H7O
Answer: 
Explanation:
a) 
: This is a non polar covalent compound which are held by weak vanderwaal forces of attraction.
b) 
: This is a covalent compound which is polar due to the presence of lone pair of electrons and are held by dipole-dipole forces of attraction.
c) : These are joined by a special type of dipole dipole attraction called as hydrogen bond. It forms between electronegative nitrogen atom and hydrogen atom and is the strongest interaction.
d) 
: This is a covalent compound and is non polar which are held by weak vanderwaal forces of attraction.
e) 
: This is a covalent compound and is non polar which are held by weak vander waal forces of attraction.
Answer:
1. guidance counselor

4.human resources worker
5. substance abuse counselor
Answer:
d sub level starts from the 3rd energy level; means you can see electrons in d sub level in any energy levels after third one.
So the answer is "In any energy levels ≥ 3"
A simple information ; s sub level is in any energy level,
p sub level is in any energy level beginning from the 2nd energy level,
d sub level appears ≥ 3rd energy level
f sub level appears in 4th energy level and over.
Hope it helps!
