The major idea behind why having a thick, heavy chimney over a thin, metal chimney for heating a home for a longer period is because it retains a lot of heat and this means energy saving, hence it fuel efficient and cost effective
A metal is a good conductor of heat, this property will make it easily give out head that is needed to the surrounding especially at night, therefore a thick chimney especially made from clay material will be a better choice over a thin metal

Answer:
d. None of the above
Explanation:
Desalination is the process of removing some mineral salts from water or soil thereby making a water more fresh and the soil less filled with mineral salts. Salty water can be desalinated by doing away with their salts leaving behind a water that would be more suitable for certain needs. Desalinated water can be used domestically, industrially and also for agriculture.
Soils that have been desalinized can be more suitable to plant some special types of crops that would not thrive where some certain mineral salts occur in excess.
Desalination is an expensive process.
Water reclamation is the reuse of waste to serve new needs. It involves recycling of waste or polluted water into a more fresher water. Reclaimed water can also be used for agricultural, domestic and industrial purposes.
Desalination is a method that can be used to reclaim water. It is also an expensive process.
Desalination recharges aquifers: Desalination is an artifical process and would not add back to the ground water storage.
Desalination provides water suitable for drinking: water reclamation also provides suitable water for drinking.
The case is acidic since calculated pH is below 7 that is 2.3
The hydroxide and hydrogen ion levels in a solution are the sources for calculating pOH and pH levels, respectively, and are the basis of whether a solution is acidic or basic
[H₃O+]=5.3×10⁻³M
To determine the hydroxide ion concentration, we use:
[OH−][H3O+]=1×10⁻¹⁴
We isolate the hydroxide ion concentration:
[OH−]=1×10−145.3×10⁻³M
Solving this, we obtain:
[OH−]=1.9×10−¹²M
We can determine whether the solution is acidic or basic by calculating the pH level:
pH=−log[H3O+]
We substitute in the hydronium ion concentration given:
pH=−Log(5.3×10−3)pH=2.3
Since the pH is below 7, the solution is acidic
