Explanation:
When carbon atom tends to form single bonds then its hybridization is 
, when carbon atom tends to form double bond then its hybridization is 
and when a carbon atom is attached to a triple bond or with two double bonds then its hydridization is sp.
For example, in HCN molecule there is a triple existing between the carbon and nitrogen atom.
So, hybridization of carbon in this molecules is sp. Moreover, nitrogen atom is also attached via triple bond and it also has a lone pair of electrons. Hence, the hybridization of nitrogen atom is also sp.
Thus, we can conclude that s and p type of orbitals overlap to form the sigma bond between C and N in H−C≡N:
A chemical reaction is a process in which one or more substances referred to as reactants are converted into one or more substances referred to as products.
- A chemical reaction can be defined as a chemical process that gives as a result one or more substances referred to as products of that reaction.
- A chemical reaction is catalyzed by specific proteins called enzymes, which are capable of lowering the activation energy of a chemical reaction.
- The most common types of chemical reactions include decomposition, synthesis, single and double replacement.
In conclusion, a chemical reaction is a process in which one or more substances referred to as reactants are converted into one or more substances referred to as products.

Answer:
Q = 4019.4 J
Explanation:
Given data:
Mass of ice = 20.0 g
Initial temperature = -10°C
Final temperature = 89.0°C
Amount of heat required = ?
Solution:
specific heat capacity of ice is 2.03 J/g.°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 89.0°C - (-10°C)
ΔT = 99°C
Q = 20.0 g ×2.03 J/g.°C × 99°C
Q = 4019.4 J
Answer:
an exothermic reaction that Increase in entropy
