Answer: 2.51 moles of oxygen is consumed
Explanation:
Exothermic reaction : It is a type of chemical reaction where the energy is released into the surrounding. In the exothermic reaction, the energy of reactant are more than the energy of product.
In exothermic reaction, the change in enthalpy is, negative
The balanced chemical reaction is:
According to stoichiometry:
When 1 mole of oxygen is consumed , energy released = 285.8 kJ
285.8 kJ of energy is evolved when oxygen consumed = 1 mol
Thus whn 717.4 kJ of energy is evolved when oxygen consumed = moles
2.51 moles of oxygen is consumed

Explanation:
Exothermic reactions are those reactions in which heat is released.
Reactants→products+heat
For example, formation of ammonia from nitrogen and hydrogen is an exothermic reaction.
N2(g)+3H2(g)→2NH3(g)+92.2kJ
Endothermic reactions are those reactions in which heat is absorbed.
Reactants+heat→products
For example, dissociation of ammonia into nitrogen and hydrogen is an endothermic reaction.
2NH3 (g)+92.2kJ→
N2(g)+3H2(g)
Answer:
C2H5OH - 9 atoms
Explanation:
2C
5H
1O
1H
I think you wrote the formula for ethanol wrong but still with the one you wrote it is still 9.
