1) To find the change in enthalpy, determine the difference between the potential energy of the products and the potential energy of the reactants. (on this diagram, C-A) To find the activation energy, find the difference between the potential energy of the reactants and the "peak" of the curve (on this diagram, B-A). For this diagram, both the enthalpy and activation energy are positive.
2) If the reaction was exothermic, enthalpy would be negative, and the potential energy of the reactants would be greater than the potential energy of the products.
Correct option is B ethyl ethanoate
The following compound is ester R−COO−R ′ and the naming of ester are done on the basis of alkanoate group (R−COO−) and alkyl (R ′ ) combined to form ester.The suffix for ester is "-oate". The full name of ester is like alkyl alkanoate. Thus the name of given compound is ethyl ethanoate.

I believe the answer is a compound because compounds can be separated when put together while mixtures can not.
Answer:
22.29%
Explanation:
Percent yield = experimental yield / theoretical yield * 100
= 12.89 / 57.82 * 100 = 22.29%
<u>Answer:</u>
photoelectric effect and the modifications to the Rutherford model is necessary
<u>Explanation:</u>
Photoelectric effect refers to emission of electrons when a light of certain frequency falls into a metal surface or a metal atom.
Rutherford, through his alpha particle scattering experiment, proposed the emission of electrons, in which he used a thin gold foil and high energy alpha particle were directed to the foil. He suggested that any light can emit electron from any metal surface.
