Answer:
B) Regeneration
the action or process of regenerating or being regenerated, in particular the formation of new animal or plant tissue.

The equation is:
Ca(OH)₂(s) + 2 HCl(aq) → CaCl₂(aq) + 2 H₂<span>O(l)
</span>
n=mass in g/M.M
15 g Ca(OH)₂ is n=15 g/ 74.1 g/mol=0.2024 mol of Ca(OH)₂
no. of mol of HCl:
n=0.5 mol/L*0.075L=0.0375 mol
This could react with 0.0375/2= 0.01875 mol of Ca(OH)₂ We have a lot more than that.
Therefore, HCl is the limiting reagent and determines how much CaCl₂ forms.
Based on the balanced reaction, 2 moles of HCl gives 1 mole of CaCl₂
no. of mol of CaCl₂= 0.0375/2= 0.01875 mol
mass in g=n*MM= 0.01875*111= 2.08 g

Answer:
Few important points related to 
reaction:
1. is a one-step reaction that follows second order kinetics.
2. In reaction, a transition state is formed in situ.
3. Strong nucleophiles like 
are used in case of bi-molecular nucleophilic substitution reaction.
Ethyl acetate can be prepared by a second-order nucleophilic substitution reaction between acetic acid and ethyl bromide.
The reaction between acetic acid and ethyl bromide is drawn below:
<span>A good is rivalrous if its consumption by one consumer prevents or impedes its use by other consumers. Roads are rivalrous to the extent that they are subject to congestion, since congestion is caused by use of the road and impedes the use of the road by others. However, a road which is not subject to congestion, like the toll road in this case, is non-rivalrous. A good is excludable if it is possible to prevent those who have not paid for it from using it. So a toll road is by design an excludable good. Hence, the toll road is rivalrous and excludable.</span>
