Answer
Commercial farming is a large-scale production of crops for sale, intended for widespread distribution to wholesalers or retail outlets.
Answer : The reactant acid and conjugate base in this reaction is, 
and 
.
Explanation :
Conjugate acid : A species that is formed by receiving of a proton 
by a base is known as conjugate acid.
Conjugate base : A species that is formed by donating of a proton by an acid is known as conjugate base.
The given chemical reaction is,
In this reaction, 
(base) react with (acid) to give 
(conjugate acid) and (conjugate base).
Therefore, the reactant acid and conjugate base in this reaction is, and .
The scenario doesn’t show up.

Answer:
The initial temperature of helium was T1 = 232.23 K
Explanation:
Given data:
Initial volume V1 = 5 L
Initial pressure P1 = 699 mmHg
Final pressure P2 = 800 mmHg
Final volume V2 = 5.7 L
Final temperature T2= 303 K
Initial temperature T1 = ?
Solution:
Formula:
P1V1/T1 = P2V2/T2
T1 = T2 × P1V1/P2V2
T1 = 303 K × 699 mmHg × 5 L / 800 mmHg × 5.7 L
T1 = 1058985/ 4560
T1 = 232.23 K
initial temperature of helium was 232.23 k.
