Answer:
1700 kj
Explanation:
The given reaction is exothermic reaction.
Exothermic reaction:
The type of reactions in which energy is released are called exothermic reactions.
In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.
For example:
Chemical equation:
C + O₂ → CO₂
ΔH = -393 Kj/mol
it can be written as,
C + O₂ → CO₂ + 393 Kj/mol
Chemical equation:
2Al + Fe₂O₃ → Al₂O₃ + 2Fe + 850 Kj
when one mole of Fe₂O₃ react 850 kj energy is produced.
when 2 moles react,
2 × 850 kj = 1700 kj
Answer:
A cation is a positively charged ion, with fewer electrons than protons, while an anion is negatively charged, with more electrons than protons. Because of their opposite electric charges, cations and anions attract each other and readily form ionic compounds.
Explanation:
its science
From the word mono means one, monochlorination refers to chlorination of a single chlorine atom. Multiple chlorinations would then be possible.
