Answer: Heat of melting s = 333 kJ/kg and heat of vaporisation r= 2160 kJ/kg
Explanation:
<h2>Given reaction:
</h2><h2>C2H2 + 2H2 → C2H6
</h2><h2>This reaction represents: Combination reaction </h2>
Explanation:
When two or more substances react and form some new substance it is called as chemical reaction .
A + B --> C + D
(reactants ) (products )
Types of chemical reaction
we come across different types of reactions that occur in nature .
Out of them , combination is also one type
Combination reaction
It is a reaction ,when two or more reactants react to form single product .
i.e A+B-----AB(IN THIS ONE SINGLE PRODUCT IS FORMED )
- This reaction can be between element element , element compound or compound compound .
LIKE : H₂+Cl₂------HCL
(E) (E) (PRODUCT )
SO₂+O₂----SO₃
© (E) (PRODUCT )
CO₂+H₂O----H₂CO₃
In the above asked equation :
C₂H₂ + 2 H₂ --> C₂H₆
- The ethane is formed by combination reaction
- This reaction obeys law of conservation of mass as it is balanced .
I am currently learning this and I would say Suspensions!
Hope this helps :)
thermometer my friend since it is a measureful device
thanx
heyaaaa
