Answer:
Elements in the same group have the same number of valence electrons.
Explanation: Science.
A chemical element is a substance that is made up of only one kind atom.
avogadros law states that under constant temp n pressure, volume of a gas is directly proportional to amount of gas
amount of gas1 = 352millimoles
amount of gas2 = 352+100 = 452millimoles
new vol = old vol x 452/352 = 25.2 x 452/352
= 32.4 mL
