<u>Answer:</u> The experimental van't Hoff factor is 1.21
<u>Explanation:</u>
The expression for the depression in freezing point is given as:
where,
i = van't Hoff factor = ?
= depression in freezing point = 0.225°C
= Cryoscopic constant = 1.86°C/m
m = molality of the solution = 0.100 m
Putting values in above equation, we get:
Hence, the experimental van't Hoff factor is 1.21
I think it’s a baller for you and your
I believe the answer is 2
Answer:
The equation for this reaction is:
2Al(OH)3 (aq) + 3H2SO4 (l) ---> Al2(SO4)3 (s) + 6H2O (l)
Explanation:
Answer:
Explanation:
Combination Reaction: is a reaction that occurs when two or more reactants combine to form a single new products. The reactants can either be Elements or Compounds. It does not require heat during the reaction.
A + B ---------> C
C (s) + O2 (g) ----------> CO2 (g)
CaO (s) + H2O (l) ---------> Ca(OH)2 (s)
In this reaction, energy is released.
Decomposition Reaction: is a reaction that occurs when a a single reactant is broken down to form two or more products. Application of heat is usually required in this type of reaction.
Δ
AB ---------> C + D
Δ
CaCO3 (s) --------> CaO (s) + CO2 (g)
In this reaction, energy is absorbed.
