Answer : The concentration of the is, 0.115 M
Explanation :
Using dilution law,
where,
= basicity of an acid = 1
= acidity of a base = 1
= concentration of = 0.125 M
= concentration of KOH = ?
= volume of = 25 ml
= volume of NaOH = 27.07 ml
Now put all the given values in the above law, we get the concentration of the .
Therefore, the concentration of the is, 0.115 M
The new volume will be 33.5 L.
Explanation:
The kinetic theory of gases confirm that the volume occupied by gas molecules will be directly proportional to the temperature of the molecules and inversely proportional to the pressure of the molecules. We can consider the moles to be n = 1. Then, the equation for the gases will be
PV = nRT
Here, P is the pressure, V is the volume, R is the gas constant and T is the temperature.
So, P = 523 Torr, T = 7.50 °C = 7.50+273.15 = 280.65 K and the gas constant R = 62.363 Torr L mol⁻¹K⁻¹.
Thus, the new volume will be 33.5 L.
I think it is 25 degrees F.

A.) 3 H2SO4 + 2 Al > Al2(SO4)3 + 3 H2
6 H+ +3 S +12 O +2 Al> 2 Al + 3S + 12O + 6H+
This one is balanced, with 6 H, 3 S, 12 O, and 2 Al on both sides.
B.) 2KCl + Pb(NO3)2 > KNO3 + PbCl2
2K + 2Cl + Pb + 2N +6 O > 1 K + 1 N+ 3 O + Pb + 2 Cl
This one is not balanced as there is 2 K, 6 O and 2 N on the reactants side but only 1 K, 3 O, and 1 N on the products side.
Therefore, only A.) is balanced
