The molar mass of Ca(ClO4)2 is 239.1 g/mol.
N2(g)+3H2 >>>>>2NH3(g)
the mole ratio between N2, H2 and NH3. It is 1 : 3 : 2
mole N2 present
moles H2 present = 25.0 g H2 x 1 mole H2/2 g = 12.5 moles H2 present
Based on mole ratio, N2 is limiting in this situation because there is more than enough H2 but not enough N2.
moles NH3 that can be produced = 1 mole N2 x 2 moles NH3/mole N2 = 2 moles NH3 can be produced
grams of NH3 that can be produced = 2 moles NH3 x 17 g/mole = 34 grams of NH3 can be produced
The awnser is A :)
****************************
The reaction proceeds through nucleophilic acyl substitution reaction.
Phenyl magnesium bromide substitutes one ethoxide ion in the nucleophilic acyl substitution reaction that drives the process forward. A subsequent equivalent of phenyl magnesium bromide produces triphenyl methanol through a nucleophilic addition reaction with the resultant keto group.
There are two ethoxy leaving groups in diethyl carbonate. Tertiary alcohol is created when diethyl carbonate combines with too much Grignard reagent. The Grignard reagent attacks the carbonyl carbon three times in the mechanism to produce the tertiary alcohol.
The mechanism is shown below:
