The reduction of 3-pentanone with hydrogen in the presence of a nickel catalyst will yield The reduction of 3-pentanone with hydrogen in the presence of a nickel catalyst will yield .a. 3-pentanol. b. pentane. c. 2-pentene. d. diethyl alcohol. e. pentanaldehyde.

d. diethyl alcohol

Explanation:

When ketones undergo reduction, they produce 2° alcohol, and 3-pentanone will produce dimethl alcohol as the secondary (2°) alcohol

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
