Explanation:
The specially designed microwave units , for the synthesis , are often very expensive and at times get heated up .
The home microwave is suitable only in some case .
And , new modification done on the home microwave , increases the safety factor .
The chemical reactions which need to be done at very high pressure , are preferred to be carried in specially designed oven .
Hence ,
the home microwave is suitable only for some selected and specific reactions .
Answer:
b
Explanation:
because it freezer in temperature
Gold heats up about seven times faster than aluminium because gold has less (<span>different) numbers of particles per unit mass. Gold has greater atomic mass (197 g/mol) and greater atomic radius (size) of an atom than aluminium (27 g/mol) metal. Amount of substance is equal to mass of substance divided with molar mass of substance.</span>
