Hey there!:
Molarity HCl = 3.5 M
Volume HCl = ?
Molarity NaOH = 2.0 M
Volume NaOH in liters = 50.0 mL / 1000 => 0.05 L
Number of moles NaOH:
n = M * V
n = 2.0 * 0.05
n = 0.1 moles of NaOH
Given the reaction:
HCl + NaOH = NaCl + H2O
1 mole HCl --------- 1 mole NaOH
1 mol HCl reacts with 1 mol NaOH , so moles NaOH = moles HCl
0.1 moles of NaOH = 0.1 moles of HCl
Therefore:
M( HCl ) = n / V
3.5 = 0.1 / V
V = 0.1 / 3.5
V = 0.029 L in mL : 0.029 * 1000 => 29.0 mL
hope that helps!
When water condenses, aka changes from gas to liquid, it releases the most heat energy. Your answer is condensation.

Answer:
See explanation
Explanation:
According to the kinetic molecular theory, the molecules that compose a gas are in constant random motion.
The temperature of a gas is a measure of the average kinetic energy of the gas molecules.
When the balloon was placed in a hot water bath, the balloon becomes larger because the gas inside the balloon expands. This is because, more kinetic energy is supplied to the molecules of the gas hence they spread out.
When the balloon is placed in cold water, the kinetic energy of the gas molecules in the balloon decreases as temperature decreases hence the balloon shrinks
When P1/P2 = C1/C2
and C is the molarity which = moles/volume
so, P1/P2 = [(mass1/mw)/volume] / [(mass2/mw)/volume]
P1/P2 = (mass1/mw)/1.5L / (mass2/mw)/1.5L
so, Mw and 1.5 L will cancel out:
∴P1/P2 = mass1 / mass2
∴ mass 2 = mass1*(P2 / P1)
= 0.278g * (78 bar / 62 bar)
= 0.35 g
∴ the quantity of argon that will dissolve at 78 bar = 0.35 g
