Sorry it’s a bit blurry, you should be able to make it out
Answer:
Fixed volume is the property of liquid and solid which means that the volume of both solid and liquid remain fixed or constant under fixed temperature and pressure.
Elastic Volumes makes it easy to dynamically increase capacity, tune performance, and change the type of any new or existing current generation volume with no downtime or performance impact.

First reaction is a Condensation Reaction. As a amall molecule (water) is evolved with the production of ether this is called as condensation of alcohols.
Second reaction is Addition Reaction also known as electrophilic addition reaction. Here HBr is added across double bond to yield alkyl halide.
Third reaction is Elimination Reaction. In this reaction tertiary alcohol is treated with base. A unsaturated compound is formed in this reaction.
Last reaction is Substitution Reaction (Aromatic Electrophilic substitution reaction. In this case a electrophile on benzene (Proton) is substituted with another electrophile (Bromine)
Answer:
Ca(OH)2 will not precipitate because Q<Ksp
Explanation:
Ksp for Ca(OH)2 has already been stated in the question as 8.0 x 10-8mol2dm-6
The value of the reaction quotient depends heavily on the concentration of the reactants. As the initial concentration of the calcium carbide decreases considerably, the reaction quotient decreases until Q<Ksp hence the Ca(OH)2 will not precipitate from solution.
The reaction equation is:
CaC₂(s) + H₂O ⇒ Ca(OH)₂ + C₂H₂
From
Ca(OH)2= Ca2+ + 2OH-
Concentration of solution= 0.064×1/64= 1×10-3
Since [Ca2+] = 1×10-3
[OH-]= (2×10-3)^2= 4×10^-6
Hence Q= 4×10^-9
This is less than the Ksp hence the answer.
