CH
Explanation:
The empirical formular is the simplest formular of a compound. It shows the relative number of elements present in a compounds. It shows the number of atoms of elements present in simple ratios.
In both compounds, the ratio of the carbon to hydrogen s 1:1
In C2H2;
C : H = 2 : 2 (Which is equivalent to 1 : 1)
In C6H6;
C : H = 6 : 6 (Which is equivalent to 1 : 1)
This means the empirical formular is CH
Answer:
- 20 J
Explanation:
Heat of Reaction = Heat of Products - Heat of Reactants
