Protons are positive
Neutrons are neutral
Electrons are negatively charged
Answer:
The main difference is their energy level, 2s orbital is higher than 1s orbital.
Energy released from cell respiration is know as ATP
Answer: 1.8 x 10^1 or the scientific e notation is: 1.8e1
Answer is: the approximate freezing point of a 0.10 m NaCl solution is -2x°C.
V<span>an't
Hoff factor (i) for NaCl solution is approximately 2.
</span>Van't Hoff factor (i) for glucose solution is 1.<span>
Change in freezing point from pure solvent to
solution: ΔT = i · Kf · m.
Kf - molal freezing-point depression constant for water is 1,86°C/m.
m - molality, moles of solute per
kilogram of solvent.
</span>Kf and molality for this two solutions are the same, but Van't Hoff factor for sodium chloride is twice bigger, so freezing point is twice bigger.
