Answer:
Explanation:
<u>1) Data:</u>
a) Solute: acetone
b) Solvent: benzene
c) n (solute) = 0.863 mol
d) mass of solvent = 500 g = 0.500 Kg
e) ΔTf = 8.84 °C
f) Kf = ?
<u>2) Formulae:</u>
- Depression of freezing point: ΔTf = m . Kf
- Molality: m = n (solute) / kg solvent
<u>3) Solution:</u>
a) m = 0.863 mol / 0.500 kg = 1.726 m
b) Kf = ΔTf / m = 8.84°C / 1.726 m = 5.12 °C/m ← answer
Answer:
Heterogenous
Explanation:
Mud is a mixture of water and soil
It’s organized by the atomic number which is the protons so the answer is A although they can be organized through groups and periods if valance electrons are included
Pressure since pressure is defined as force per unit area and the molecules exert a force on the walls of the container when they bombard it
B reactants then C is on the right side! If you take h2O and air (the reactants) then the product would be a snowflake. happy holidays!!
