When 2 moles of Fe(s) react with Cl2(g) to form FeCl3(s) according to the following equation, 799 kJ of energy are evolved.
1 answer:
Answer:
1. Exothermic.
2. -1598 kJ.
Explanation:
Hello!
1. In this case, according to the reaction, we can infer that 799 kJ of energy are evolved (given off, released) it means that the enthalpy of reaction is negative as the reactants have more energy than the products; which means this is an exothermic reaction.
2. Here, as we know that the enthalpy of reaction is -799 kJ/mol, we can compute the q-value as shown below, considering the reacted 2 moles of solid iron:
Which means that 1598 kJ of energy are evolved when 2 moles of solid iron react.
Best regards!

Answer:
Explanation: Covalent Bond is the bond which is formed by the sharing of electrons form one atom to another in order to complete the octet of valence shell of electrons.
The strength of the covalent bond is measured by the its dissociation energy. Higher the tightly bounded the nucleus of the 2 atoms, more energy would be require to break the bond thus higher the dissociation energy. Thus the triple bond will be requiring more of the energy to break it rather than the single bond .
