Answer:
H2O2 → H2O + 1/2O2
Explanation:
0.0800 mol of H2O2 decomposed into 0.0800 mol of H2O and 0.0400 mol of O2
H2O2 → H2O + 1/2O2 - Descomposition reaction.
Answer:
Explanation:
The formula for the change in freezing point ΔT_f caused by an electrolyte is
1. Calculate i
Na₂SO₄(aq) ⟶ 2Na⁺(aq) + SO₄²⁻(aq)
1 mol Na₂SO₄ gives 3 mol ions.
i = 3
2. Calculate the freezing point
(a) Change in freezing point
(b) Freezing point
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
Answer: Option (B) is the correct answer.
Explanation:
As the given reaction is as follows.
Equilibrium constant for this reaction will be as follows.
According to Le Chatelier's principle, when we increase the temperature then the equilibrium will shift towards the right hand side.
As a result, concentration of carbon dioxide will decrease whereas concentration of carbon monoxide will increase.
Thus, we can conclude that in the given reaction equilibrium constant for this reaction will decrease with increasing temperature.
