Answer:
The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.

Using ideal gas equation,
PV=nRT
P=199 kpa
V=4.67 L
T=30+273K= 303K
n= number of moles of gas
R=8.321 L·kPa·K-1·mol-1
So using ideal gas equation,
n=PV/RT
=199*4.67/8.321*303\
=0.37 mol
You would divide the number of atoms by Avogadro's number [6.02x10^23]
Answer:I am not sure how
Explanation: sorry free trial
A solvent and an example would be water because it is polar and has the ability to dissolve many solutes, hence it is referred to as the universal solvent.
