Answer:
the answer is D my friend
Explanation:
one mole= 6.02x10^23
Everything going from a mole will always be multiplied and everything going into mole will be divided.
The answer to your question is : no.of moles of Si = 43/atomic mass of Si = 43/28.1 = 1.53
according to reaction 3 moles of Si gives 1 mole of Si3N4
so 1.53 mole of Si will give 1.53/3 = 0.51 mole of Si3N4
molar mass of Si3N4 = 140.28 g/mole
it means that 1 mole of Si3N4 = 140.28 g
so 0.51 mole of Si3N4 = 0.51 X 140.28 = 71.543 g
Answer:
DeltaG0 = -(1) X 96485 X 0.034 = -3280.49 J /mole = -3.281 KJ / mole
Explanation:
E0cell = E0cathode - E0anode
the cathode will be with more reduction potential and anode will have low reduction potential
E0cell = 0.254 - 0.220 = 0.034 V
Now
DeltaG0 = -nFE0cell
E0cell = 0.034 V
F = 96485 C
n = 1
Putting values
DeltaG0 = -(1) X 96485 X 0.034 = -3280.49 J /mole = -3.281 KJ / mole
Answer:
; The structures of both compounds are shown in the attached image.
Explanation:
First, compound W has the molecular formula C6H11Cl, it is observed that it does not have double bonds. removal of E2 produces compound Y, which is an alkene, which is hydrogenated and produces a methylcyclopentane.
Compound W is an alkyl halide that undergoes an SN1 reaction with sodium iodide in the presence of acetone forming the corresponding iodine compound.
while compound X is a tertiary alkyl halide, it is sterically restricted to undergo SN2 reactions.
