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
Explanation:
To balance a chemical equation, there are so many approaches to solve the problem.
A balanced chemical equation is one that obeys the law of conservation of matter.
According to this law "matter is neither created nor destroyed by atoms are just rearranged in chemical reaction".
This implies implies that equal number of atoms must be on both sides of the equation.
There are two main approaches to balancing chemical equation;
- Inspection
- mathematical equation
We can inspect the equation and affix the proper coefficients to combining species.
Mathematically, we establish simple solvable algebraic equations to find the number of respective coefficients that will balance the equation:
For example:
H₂ + O₂ → H₂O
mathematically;
aH₂ + bO₂ → cH₂O
conserving:
H : 2a = 2c
O: 2b = c
let a = 1
c = 1
b =
multiply by 2 to give;
a = 2, b = 1 , c= 2
2H₂ + O₂ → 2H₂O
