What are the following answers?
Then product forms at the cathode is Fe metal
Fei3 undergo dissociate to form fe^ 3+ + 3I^-
Fe^3+ move to the negative electrode(cathode) where they are reduced to metallic iron by gaining 3e-
that is Fe^3+(aq) + 3e- = Fe(s)
Answer 3Sn+ 4H3pO4= 6H2+Sn(PO)4
1 Sn 3 Sn
3 H 2 H
1 P 4 P
4 O 16 O
then you have to make the numbers the same for each side
so you get by putting the 3 infront of Sn 4 infront of the H3PO4 and 6 infront of the H2
3 Sn 3 Sn
12 H 12 H
4 P 4 P
16 O 16 O
Answer:
The molar mass and atomic mass are essentially the same for an element
Explanation:
The molar mass of a substance can be obtained by dividing the mass of the substance by the no of moles of the substance present.
The atomic mass of an element is the number of protons and neutrons present in the substance.
These two measurements usually give the same values because they both make reference to the 1/12th the mass of carbon-12 for their measurement.
Because they both have the same reference point, though they have different calculating procedures, the results obtained will be similar.
