Answer: -
4C₂H₅ + 13 O₂ → 8 CO₂ + 10 H₂O
Explanation: -
The given equation is
C₂H₅ + O₂ → CO₂ + H₂O
Balancing for H,
2C₂H₅ + O₂ → CO₂ + 5H₂O
Balancing for C
2C₂H₅ + O₂ → 4CO₂ + 5H₂O
Now right hand side we are getting 13 O which is an odd number.
In order to balance O, we first try to even out the number of O on right side by multiplying whole equation by 2.
4C₂H₅ + 2O₂ → 8CO₂ + 10H₂O
Now balancing for O
4C₂H₅ + 13 O₂ → 8 CO₂ + 10 H₂O
I’m pretty sure the answer is A.
<h2>The required option d) "specific heat" is correct.</h2>
Explanation:
- To raise the temperature of any substance or material of certain mass to respective temperature it requires some amount of heat.
- Specific heat is the amount of heat necessary to raise the temperature of the substance of 1 gram to 1 Kelvin.
- It is the amount of heat which is required to raise the temperature per unit mass to per unit temperature.
- Thus, the required "option d) specific heat" is correct.
