Answer:
1) Which letter (a–f) represents potential energy (ΔH) of the products?
2) Which letter (a-f) represents potential energy (ΔH) of the activated complex?
3) Which letter (a-f) represents potential energy (ΔH) of the reactants?
Explanation:
The graph ploted represents the changes in the chemical potential (stored) energy for the reaction X + Y → Z as long as it evolves from reactants to products.
The left side of the graph shows the potential energy of the reactants, X and Y, when the reaction has not yet occurred.
Thus, the letter (a) is the potential energy of the reactants.
Moving from left to right you see that the potential energy increases, until a maximum. The maximum is when the reactants (X and y) have reacted up to an intermediate stage, in which there exists a transition state featured by an activated complex whose structure is half-way between the reactants and the products.
Thus, the letter (c) represents the potential energy of the activated complex.
At the far right of the graph, the reaction has gone to completion, the activated complex ends the transition state and the final products are formed. Thus, the letter (e) represents the potential energy of the products (Z).
All those energies are measured with respect to the same base line (the x-axis).
The attached graph has some labels added to help to identify the 3 stages: reactants, activated complex, and product.
Potential energy of products, reactants and activated complex in an energy profile diagram are displayed right end, left end and at the highest point of the diagram, respectively. However, the corresponding letters (a-f) would depend on the specific diagram.
In general, when you look at an energy profile diagram, the potential energy (ΔH) of the products is usually represented by the energy level of the products on the right side end of the diagram, which could be any of the letters a-f but depends on the specific diagram given. Similarly, potential energy (ΔH) of the reactants can be represented by the energy level of the reactants on the left end of the diagram. The potential energy (ΔH) of the activated complex, also known as the transition state, is usually the highest point on the diagram, indicating the highest energy level.
It's important to keep in mind that these are general guidelines for interpreting an energy profile diagram. The actual answer to your question (potential energy, activated complex, and reactants would depend on the specific diagram you're looking at.

(2) a ketone (4) an ester
Answer : The correct option is, (4) an ester.
Explanation :
As we know that an organic acid is an organic compound that has the properties of an acid. For example : Acetic acid.
And the alcohol is an organic compound that contains one or more hydroxyl groups attached to a carbon atom. Fro example : Ethanol.
When an organic acid react with an alcohol the it produces an ester.
For example : when an organic acid (acetic acid) react with an alcohol (ethanol) to gives an ester (methoxyethane).
The balanced chemical reaction will be,
Hence, the reaction between an organic acid and an alcohol produces an ester.
Answer:
If they are both non-metals
Explanation:
covalent = non-metal + non-metal
ionic = metal +non-metal
metallic = metal +metal
The particles in a solid are farther apart than the particles in a liquid.
The particles in a solid are closer together than the particles in a liquid.
The arrangement of a solid's and a liquid's particles will depend on the mass of the substance.
Answer:
D. 27 13 Al
Explanation:
13 protons means atomic number 13. The periodic table says element 13 is aluminum (Al). 27 is the atomic mass, made up of 13 protons (1 each) and 14 neutrons (also 1 each) for a total of 27 atomic mass.
The answer to this question is 19
