The number of sigma and pi bonds are,
Sigma Bonds = 16
Pi Bonds = 3
Explanation:
Every first bond formed between two atoms is sigma. Pi bond is formed when already a sigma bond is there. While in case of Alkyne (triple Bond) there is one sigma and one pi bond already present, so the third bond is formed by second side-to-side overlap of orbitals, hence, a second pi bond is formed.
Below all black bonds are sigma bonds, while in alkene there is one pi bond and in alkyne there are two pi bonds.

Answer:
The mass of the surrounding is
Explanation:
From the question we are told that
The mass of is
The mass of water is
The chemical equation for the dissociation process is
The specific heat capacity of the mixture is
The combined mass of the solution is
The mass of the surround here is the mass of the coffee-cup calorimeter and this contain the mixture ( water and the NaOH ) so the mass of the surrounding is
