Answer:
The answer to your question is below
Explanation:
H₂SO₄ = sulphuric acid
KOH = potassium hydroxide
This is a neutralization reaction
H₂SO₄ + 2 KOH ⇒ K₂SO₄ + 2H₂O
2 ----------- K ----------- 2
1 ----------- S ---------- 1
4 ---------- H --------- 4
6 ------------ O ---------- 6
Answer:
Enthalpy of solution is 583.67 J
Explanation:
The mass of water is 143 g
The mass of NaCl added = 12g
Total mass of solution will be = 
The specific heat of solution = specific heat of water = 4.184 J /g °C
The initial temperature = 22.5°C
Final temperature =21.6°
The change in temperature = 
The enthalpy of solution will be equal to the heat change in the solution.
The heat change of solution will be calculated as:
Thus the enthalpy of solution is 583.67 J (Endothermic reaction)
The atomic number of an element gives the element it's identity. This is also known as the number of protons within an element. If you have the number of protons but don't know the element's atomic mass, add the protons and neutrons to get the mass number.

Answer:
Percent ionic character is defined as the ratio of a bond’s actual dipole moment to the dipole moment it would have if the electron were completely transferred from one atom to the other, multiplied by 100
Explanation:
The percent ionic character seeks to establish the amount of electrovalency in a particular compound. It simply compares the covalency i.e extent of shared electrons to the the electrons that are transferred.
It is given as the ratio of the acutal dipole moment to the dipole moment due to ionic character of the bond multiplied by 100:
Percent ionic character = μ_obs/μ_ionic x 100
Where μobs is the actual dipole moment and μ ionic is the dipole moment if the bonds were 100% ionic.
