Explanation:
A balanced equation is the one which contains equal number of atoms on both reactant and product side.
For example,
Number of atoms on reactant side are as follows.
- Ca = 1
- O = 6
- H = 5
- P = 1
Number of atoms on product side are as follows.
- Ca = 3
- O = 9
- H = 2
- P = 2
Therefore, to balance the chemical equation multiply by 3 and multiply
by 2 on reactant side. Whereas multiply
by 6 on product side.
Hence, the balanced chemical equation will be as follows.

Answer:
Coefficient in front of the in the balanced equation - 1
Explanation:
The unbalanced Chemical equation is shown below as:-
On the left hand side,
There are 1 boron atom and 3 fluorine atoms and 1 sodium and hydrogen atoms.
On the right hand side,
There are 2 boron atoms and 6 hydrogen atoms and 1 sodium and fluorine atoms.
Thus,
leftside, must be multiplied by 2 to balance boron and right side,
must be multiplied by 6 to balance fluorine. Left side,
must be multiplied by 6 to balance sodium and hydrogen atoms.
Thus, the balanced reaction is:-
<u>Coefficient in front of the in the balanced equation - 1</u>
Answer:
The degree of dissociation of acetic acid is 0.08448.
The pH of the solution is 3.72.
Explanation:
The
The value of the dissociation constant =
Initial concentration of the acetic acid = [HAc] =c = 0.00225
Degree of dissociation = α
Initially
c
At equilibrium ;
(c-cα) cα cα
The expression of dissociation constant is given as:
Solving for α:
α = 0.08448
The degree of dissociation of acetic acid is 0.08448.
The pH of the solution ;
