The minimum amount of energy that has to be added to start a reaction is the activation energy, which starts the reaction. It activates it.
Answer:
1.08mol
Explanation:
moles = reacting mass/ molecular weight
reacting mass = 80.0g molecular weight of Ca[OH]2= 40 + 2(16 +1) = 74g/mol
mole = 80.0/74 = 1.08mol
Answer:
Explanation:
When potassium chloride reacts with lead acetate in aqueous medium, it gives white precipitate of lead chloride and potassium acetate in aqueous medium as a product.
As shown in chemical reaction given below:
Answer:
Explanation:
Let's consider the following chemical equilibrium:
CaCO₃(s) ⇄ CaO(s) + CO₂(g)
Given the pressure equilibrium constant Kp = pCO₂
We can calculate the concentration equilibrium constant (Kc) using the following expression.
where,
R is the ideal gas constant
T is the absolute temperature
Δn(g) = moles of gaseous products - moles of gaseous reactants = 1 - 0 = 1
The expression for this reaction is:
