Answer:
0.3097 moles of an nonionizing solute would need to be added.
Explanation:
Molal elevation constant =
Normal boiling point of ethanol =
Boiling of solution =
Moles of nonionizing solute = n
Mass of ethanol (solvent) = 47.84 g
Elevation boiling point:
n = 0.3097 mol
0.3097 moles of an nonionizing solute would need to be added.
Answer:
I do not think it will happen
Explanation:
The result is not general and can only occur when there is higher temperatures and pressure. Only when there's high temperature and pressure, will the solution precipitate.
More so; kinematically, the result is limited though it can happen in thermodynamics environment.
Answer:
Strontium
Explanation:
To find the element, we need to know the atomic number. There is this rule in chemistry that says that the number of protons and the atomic number are the same. Since we know that there are 38 protons, the atomic number is also 38, leading us to Strontium. Sr -- element symbol.
The mass number is located below the element symbol on a periodic table. The mass number or the atomic mass for Strontium is 87.62 u.
Since there are an uneven amount of protons and electrons, let's subtract the number of electrons from the number of protons to find the difference. 38-36 = 2. (Also, protons are positive and electrons are negative, meaning there are more + than - in the ionic charge). Which means, the atom has a +2 ionic charge.
I think Alcohol would be the correct answer, but i'm not too sure since my mind is fuzzy about chemistry
