If you are asking what cold is then cold is the absence of heat
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.
In order to change celcius to kelvin always add 73 to it leaving you with -195.93
Sodium carbonate is used to neutralised sulfuric acid, H₂SO₄. Sodium carbonate is the salt of stron base (NaOH) and weak acid (H₂CO₃). The balanced chemical reaction for neutralization is as follows:
Na₂CO₃ + H₂SO₄→ Na₂SO₄ + H₂CO₃
From balanced chemical equation, it is clear that one mole of Na₂CO₃ is required to neutralize one mole of H₂SO₄. Molar mass of Na₂CO₃= 106 g/mol=0.106 kg/mol and molar mass of H₂SO₄= 98 g/mol=0.098 kg/mol.
To neutralize 0.098 kg of H₂SO₄ amount of Na₂CO₃ required is 0.106 kg, so, to neutralize 5.04×10³ kg of H₂SO₄, Na₂CO₃ required is= kg= 5.451 X 10³ kg.
