Suggest a reasonable synthetic strategy for the synthesis of 3,5-dinitrobenzyl alcohol from benzaldehyde.
Silicon Carbide (SiC) is a ceramic material with the so-called zinc blende crystal structure. It can be constructed from the FCC unit cell using a two-atom basis consisting of a Si atom at (0,0,0) and a C atom at (¼, ¼ , ¼).
is it possible to use methylene blue to determine the concentration of ascorbic acid in orange
The combustion of ethanol, C2H6O (MW = 46.0 g/mol), produces CO2 (MW = 44.0 g/mol) and water (18.0 g/mol). In a lab experiment, the reaction occurs using 4.60 g of ethanol in a 1.00 L container at body temperature (310 K) and 0.970 atm according t..
Ammonia is made industrially by reacting nitrogen and hydrogen under pressure, at high temperature, and in the presence of a catalyst. The equation is N2(g)+3H2(g)---->2NH3(g). If 4.0mol of H2 react, how many moles of NH3 will be produced.
