Lostsunrise [7]

Answer:

Imine can be isolated from the reaction mixture as water is continuously removed from the reaction chamber

Explanation:

In this reaction, a non -aqueous solvent  is not used (not mentioned in the question). Thus, we can say that there is continuous removal water under suitable reacting conditions and hence the imine formed is left behind.

How many electrons make up a charge of -50.0 μc ? Express your answer using three significant figures?
SVETLANKA909090 [29]

The charge on one mole of electrons = 96485 C =  1 Faraday

so if charge is 96485 C the moles of electrons are 1 = 6.023 X 10^23 electrons

if charge is 1 C the number of electrons = 6.023 X 10^23 / 96485

If charge is 50 micro C the number of electrons

              = 6.023 X 10^23 X 50 X 10^-6 / 96485

             = 3.12 X 10^14 electrons

What mass of na2co3 is present in 0.650 l of a 0.505 m na2co3 solution?
Vladimir79 [104]
V=0.650 L
c=0.505 mol/L
M(Na₂CO₃)=106.0 g/mol

the amount of substance of sodium carbonate is:
n(Na₂CO₃)=vc

the mass of sodium carbonate is:
m(Na₂CO₃)=n(Na₂CO₃)M(Na₂CO₃)

m(Na₂CO₃)=vcM(Na₂CO₃)

m(Na₂CO₃)=0.650*0.505*106.0=34.7945 g
