Given that
C(s) + O₂(g) → CO₂(g); ∆H = - 395 KJ
S(s) + O₂(g) → SO₂(g); ∆H = -295 KJ
CS₂(l) + 3O₂(g) → CO₂(g) + 2SO₂(g); ∆H + -1110 KJ
The heat of formation of CS₂ is
C(s) + O₂(g) → CO₂(g); ∆H = - 395 KJ
S(s) + O₂(g) → SO₂(g); ∆H = -295 KJ
CS₂(l) + 3O₂(g) → CO₂(g) + 2SO₂(g); ∆H + -1110 KJ
The heat of formation of CS₂ is

Consider the following statements about enantiomers :
1. Isomers which are mirror images of each other are called enantiomers
2. A mixture of equal parts of enantiomers is called a racemic modification
3. Enantiomers show different properties-physical or chemical -only in a chiral medium
4. A racemic modification is converted by an optically active agent into mixture of diasteromers that can be separated.
