(NH4),CO
(NH₄)₂ CO₃
Explanation:
The chemical formula for ammonium carbonate is (NH4),CO
Ammonium carbonate is made up of:
Ammonium ion
Carbonate ion
Ammonium ion is represented by NH₄⁺
Carbonate ion is represented by CO₃²⁻
Now to write the formula, we are going to use their combining powers;
NH₄⁺ CO₃²⁻
Combining
power 1 2
Exchange
of power 2 1

C6H15, C2H5 has a molar mass of 29g/mol. 87 divided by 29 is 3. Then multiply each element subscript by 3
The change in pH is calculated by:
pOH = Protein kinase B + log [NH4+]/ [NH3]
Protein kinase B of ammonia = 4.74
initial potential of oxygen hydroxide= 4.74 + log 0.100/0.100 = 4.74
pH = 14 - 4.74=9.26
moles NH4+ = moles NH3 = 0.100 L x 0.100 M = 0.0100
moles H+ added = 3.00 x 10^-3 L x 0.100 M=0.000300
NH3 + H+ = NH4+
moles NH3 = 0.0100 - 0.000300=0.00970
moles NH4+ = 0.0100 + 0.000300=0.0103
pOH = 4.74 + log 0.0103/ 0.00970= 4.77
oH = 14 - 4.77 = 9.23
the change is = 9.26 - 9.23 =0.03
