No it would not because it’s still hard
The frozen balloon shrank because the average kinetic energy of the air molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little. This can be called contraction.
A) in pure water :
by using ICE table:
According to the reaction equation:
BaCrO4(s) → Ba^2+(aq) + CrO4^2-(aq)
initial 0 0
change +X +X
Equ X X
when Ksp = [Ba^2+][CrO4^2-]
by substitution:
2.1 x 10^-10 = X* X
∴X = √2.1 x 10*-10
∴X = 1.4 x 10^-5
∴ the solubility = X = 1.4 X 10^-5
B) In 1.6 x 10^-3 m Na2CrO4
by using ICE table:
According to the reaction equation:
BaCrO4(s) → Ba^2+(aq) + CrO4^2-(aq)
initial 0 0.0016
Change +X +X
Equ X X+0.0016
when Ksp = [Ba^2+][CrO4^2-]
by substitution:
2.1 x 10^-10 = X*(X+0.0016) by solving for X
∴ X = 1.3 x 10^-7
∴ solubility =X = 1.3 x 10^-7
Answer:
14.0067 g/mol
Explanation:
The molar mass of pure nitrogen is 14.0067 because when you look at the top right of an element on the periodic table of elements you can see the molar mass of an element. This can go for any other elements on the table, just look at the top right of the box. The molar mass of an element is also called the atomic weight. Hope this helps! :)
Molecular mass of Carbon in compound = 29.784% * 241.94 g/mol
= 72.05 g/mol
Number of moles = 72.05 / 12 = 6 [ Molar mass of Carbon = 12 ]
Now, Molecular mass of Hydrogen in compound = 4.166% * 241.94 g/mol
= 10.07 g/mol
Number of moles = 10.07 / 1 = 10 [ Molar mass of Hydrogen = 1 ]
Now, Molecular mass of Bromine in compound = 66.05% * 241.94 g/mol
= 159.80
Number of moles = 159.80 / 79.90 = 2
Empirical Formula = C₆H₁₀Br₂
Hope this helps!
