Answer: Its esterification reaction.
when organic acid react with alcohol it forms ester and water. reaction is known as esterification reaction.
CH3COOH + C2H5OH → CH3COOC2H5 + H2O
ethanoic acid + ethanol → ethyl acetate + water
this reaction takes place in the presence of acid catalyst ( dil H2SO4).
in this reaction oxygen of ethanol with lone pair act as nucleophile and carbonyl carbon of acetic acid act as electrophile.. so its nucleophilic substitution reaction of -COOH group.

Answer:
MO = 20
Explanation:
Given that: MO = 3x + 5
MN = 2x + 3
NO = 2x - 3
But,
MO = MN + NO
So that;
3x + 5 = (2x + 3) + (2x - 3)
3x + 5 = 2x + 3 + 2x - 3
3x + 5 = 4x
3x - 4x = -5
-x = -5
Multiply through by minus,
x = 5
Thus,
MO = 3x + 5
= 3(5) + 5
= 15 + 5
MO = 20
The length of MO is 20.
(A)Conductor permits the flow of electrons.
Answer:
ΔH° = -186.2 kJ
Explanation:
Hello,
This case in which the Hess method is applied to compute the required chemical reaction. Thus, we should arrange the given first two reactions as:
(1) it is changed as:
SnCl2(s) --> Sn(s) + Cl2(g)...... ΔH° = 325.1 kJ
That is why the enthalpy of reaction sign is inverted.
(2) remains the same:
Sn(s) + 2Cl2(g) --> SnCl4(l)......ΔH° = -511.3 kJ
Therefore, by adding them, we obtain the requested chemical reaction:
(3) SnCl2(s) + Cl2(g) --> SnCl4(l)
For which the enthalpy change is:
ΔH° = 325.1 kJ - 511.3 kJ
ΔH° = -186.2 kJ
Best regards.
The type of atoms present in the chemical compound and the proportion or how many specific atoms are respect to other atoms in the chemical compound.
