Which chemical equation is balanced?
2 answers:
Answer: Option (d) is the correct answer.
Explanation:
An equation will be said balanced equation when there are equal number of atoms on both reactant and product side.
For example,
Number of atoms on reactant sides are as follows.
P = 1
Cl = 5
H = 8
O = 4
Number of atoms on product side are as follows.
P = 1
Cl = 5
H = 8
O = 4
Thus, there are equal number of atoms on both reactant and product side. Hence, this equation is balanced.

Answer:
option D is correct
D. This solution is a good buffer.
Explanation:
TRIS (HOCH)
CNH
if TRIS is react with HCL it will form salt
(HOCH)
CNH
+ HCL ⇆ (HOCH
)
NH
CL
Let the reference volume is 100
Mole of TRIS is = 100 × 0.2 = 20
Mole of HCL is = 100 × 0.1 = 10
In the reaction all of the HCL will Consumed,10 moles of the salt will form
and 10 mole of TRIS will left
hence , Final product will be salt +TRIS(9 base)
H = Pk + log (base/ acid)
8.3 + log(10/10)
8.3
