Answer: The new volume is 544 L
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the new volume is 544 L
Answer:
Fe2O3 + C → 2Fe + CO3
Explanation:
The unbalanced equation given in this question is as follows:
Fe2O3 + C → Fe + C03
To balance this equation, one should ensure that the number of atoms of each element on both sides of the equation is equal. The balanced equation is as follows;
Fe2O3 + C → 2Fe + CO3
N.B, there are;
- 2atoms of Fe on both sides
- 1 atom of C on both sides
- 3 moles of O on both sides
