Lack of water may prevent the construction of a geothermal energy facility in a particular area because <span>water is used as steam to turn turbines.
</span>These turbines are turned by the power of water and in turn, they produce geothermal energy in these facilities. Without water, these operations wouldn't be able to occur. The saltiness of water, as well as mineral wastes dissolution, and the lack of heat of turbines don't really fit here as an answer.

Answer:
The glassware and solvent for the production of grignard reagent and its reaction should by dry and anhydrous so as to prevent the conversion of the grignard reagent into saturated alkane. Acetone, is not a good solvent for the generation of grignard reagent because it has the potential of forming alcohol.
Explanation:
Grignard reagent is a compound formed by the reaction of halide of alkyl or alkene with magnesium metal. This makes the compound more nucleophilic. Thus the availability of an electrophile around it will evoke a quick reaction. The presence of water in an acidic condition will generate hydroxonium ions which are highly electrophilic. There will therefore be an introduction of hydrogen ions to the grignard reagent and which will displace the MgBr leading to the formation of alkane.
Acetone tends to produce alcohol when they are exposed to grignard reagent, thus they are not appropriate to be used as solvent. This is due to the resultant highly electrophilic nature of the carbonyl carbon on the acetone, thus will react with the nucleophilic carbon on the grignard. The reaction can be represented as follows:
RMgBr + CH3(CO)CH3 + H (with hydrogen ions) >>>RCOH + Mg(OH)Br
<span>DG = DH - TDS
For this reaction DH>0 and DS<0. So, d. the reaction is not spontaneous at any temperature.</span>
I think the correct answer from the choices listed above is the last option. The elements which make up water can only be separated by chemical means; therefore, water is a compound. It<span> is a substance formed when two or more chemical elements are chemically bonded together. Hope this answers the question.</span>
