9.32 is the new volume of the balloon.
Explanation:
Data given:
Initial volume of the balloon V1 = 10 litres
initial temperature in the room T1 = 24 degrees 0r 297.15 K
final volume V2=?
final temperature T2 = 3.8 degrees OR 276.95
from the values given it is deduced that we have to apply Charles Law
=
V2 =
putting the values in the equation:
V2 -
V2 = 9.32 liter
When baloon is taken from a warm room to outside where it is cold the volume of the gas becomes 9.32 litre in the balloon
They are called dry cells because the electrolyte is a paste.
Hope this helps!

Nitric acid and calcium hydroxide react to form calcium nitrate and water.
The molecular equation is as follows:
2HNO3 (aq) + Ca(OH)2 (aq) = Ca(NO3)2 (aq) + 2H2O (l)
So the formula of calcium nitrate, the salt formed in this reaction is Ca(NO3)2 .
Water here seem to be the only real product. It is formed from the OH+ of the hydroxide and the H+ of the acid which combine to form two water molecules.
Calcium and Nitrate ions remain unchanged before and after the reaction and are thus known as spectator ions.
Answer Option D
Counting the number of atoms each side of the equation shows that the numbers balance.
Answer:
So if this is about chemical equations. You have 3 steps.
Step 1.- Count each type of atom in reactants and products.
Step 2.- Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.
Step 3.-Repeat steps 1 and 2 until the equation is balanced.
