Answer: The given reaction is a neutralization reaction.
Explanation:
When an acid chemically reacts with a base then it leads to the formation of salt and water.
For example,
Here, KOH is a the base and is an acid which on chemical reaction with each other leads to the formation of salt
and water
.
Thus, we can conclude that the given reaction is a neutralization reaction.
Answer:
the mass of CaO present at equilibrium is, 0.01652g
Explanation:
= 3.8×10⁻²
Now we have to calculate the moles of CO₂
Using ideal gas equation,
PV =nRT
P = pressure of gas = 3.8×10⁻²
T = temperature of gas = 1000 K
V = volume of gas = 0.638 L
n = number of moles of gas = ?
R = gas constant = 0.0821 L.atm/mole.k
Now we have to calculate the mass of CaO
mass = 2.95 * 10 ⁻⁴ × 56
= 0.01652g
Therefore,
the mass of CaO present at equilibrium is, 0.01652g
