Ion or Isotope: Oxide
NaOH + CH3COOH -> CH3COONa + H20
Answer:
The correct answer is option D.
Explanation:
When a chemical reaction proceeds the reactants are converted into products. The energy hill represents the potential energy of the reaction.
There are two conditions: If the reaction is endothermic than the energy of the products is greater than the energy of the reactants and ΔH is positive. This energy gain is shown in the form of a peak. In an exothermic reaction, the energy of the products is lower than the reactants and ΔH is negative.
So the suitable option is D which states that the reaction is endothermic and the potential energy gained by the products is higher when a reaction proceeds.

It is incorrect question
The molar mass of the imaginary compound Z(AX₃)₂ is the sum of the molar mass of Z, A and X.
<h3>How do we calculate molar mass?</h3>
Molar mass of any compound will be calculated by adding the mass of each atoms present in that compound.
Given compound is Z(AX₃)₂, molar mass of the given compound will be calculated as:
Molar mass of Z(AX₃)₂ = Molar mass of Z + molar mass of 2(A) + molar mass of 6(X)
Hence molar mass of Z(AX₃)₂ is the sum of the masses of all atoms.
