Answer: 13.888g
Explanation:
CaCO3 —> CaO + CO2
From the equation above, 1mole of CaCO3 produces 1mole of CaO. Since the answer is to be expressed in grams, let us covert this mole to grams. This is illustrated below:
MM of CaCO3 = 40 +12 + (16x3) = 40 + 12 + 48 = 100g/mol
MM of CaO = 40 + 16 = 56g/mol
From the equation,
100g of CaCO3 produced 56g CaO
Therefore, 24.8g of CaCO3 will produce Xg of CaO i.e
Xg of CaO = (24.8 x 56) / 100 = 13.888g
Therefore, the theoretical yield of CaO is 13.888g
solution:
A = 192 x (1/2) ^ (15/5) = 192 x (1/2) ^3 = 192 x 1/8 = 24 mg
Starting by hitting acetylene with NaNH2 to deprotonate, this C-- will attack the C connected to the Br Sn2 style to lengthen the chain by two carbons.
Do this same thing again with the other CH of the acetylene and another bromoethaneto get a six carbon chain, namely, 3-hexyne.
Now, reduce the alkyne to an alkene via H2/Pd/C, and that gives 3-hexene.
