Answer
is: 1) ccl4, kb = 29.9°c/m, carbon tetrachloride has the greatest boiling point
elevation.
The boiling point elevation is directly
proportional to the molality of the solution according to the
equation: ΔTb = Kb · b.
<span>
ΔTb - the boiling point
elevation.
Kb - the ebullioscopic
constant.
b - molality of the solution.
So the highest boiling poing elevation will be for solution with highest ebullioscopic constant because molality is the same.</span>
Answer:
D. They have the same number of protons as electrons.
Explanation:
Protons are found in the nucleus of the atom and have a positive charge while electrons orbit around the nucleus and have a negative charge. Usually, in a neutral atom of an element, the number of protons is equal to the number of electrons. This is why the atom has no charge because the positive and negative charges cancel out. When an atom loses an electron its charge turns positive while when it gains an electron its charge turns negative.

Answer:
Iron + copper(II) sulphate → iron sulphate + copper
Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
copper + silver nitrate → copper nitrate + silver
Cu (s) + 2AgNO3 (aq) → Cu(NO3)2 (aq) + 2Ag (s)
