Answer: see figure attached and explanation below.
Explanation:
1) Chemical equation (given):
Fe + CuCl₂ → Cu + FeCl₂
2) ΔHf reactants: -256 kJ/mol (given)
3) ΔHf products: - 321 kJ/mol (given)
4) ΔH reaction = ΔHf products - ΔHf reactants = - 321 kJ/mol - (- 256 kJ/mol) = - 65 kJ/mol
5) Conclusion:
i) Since ΔHf of products is less (more negative) than ΔHf of reactants, the reaction is exhotermic: the reaction released energy, which is the reason why the products content less potential energy than the reactants.
ii) Then, the energy diagram is the typical one of an exothermic reaction: the products start a certain potential energy level, the energy incrases until reaching the activation energy (the energy barrier to form the activated complex) and then energy decreases until a level below the energy of the reactants.
iii) See the attached figure with such kind of diagram showing the products at a lower level than the reactans

Atoms show us the basic proverb about the strength and the bond when they are Unity and Diversified.
<u>Explanation:</u>
- Every basic matter in the earth is composed of atoms. It is the smallest unit of the matter which is taken to observe the properties of the whole element.
- The atom consists of different energy levels and consist of protons electrons and neutrons.
- The atoms when are compactly arranged it result in the great strength required to bring the deformation in shape which shows that unity is always great.
- But in the liquid and gas, the atoms are arranged in a randomly dispersed pattern which shows that they can be separated and involved in any process easier to get the heterogeneous product easily which is an example for Diversity.
Answer:
It get thicker beacause the mid ocean
Explanation:
Because when it gets moved back the heat rises and it builds up to be thicker.
