The mixing of Ni(NO3)2(aq) and Na2CO3(aq) will result in a precipitation reaction.
Ni(NO3)2(aq) + Na2CO3(aq) =====> NiCO3(s) + 2NaNO3(aq)

21.28s
Explanation:
This is a rate problem.
Number of parts produced = 225
Time taken to produce= 8hours
Rate of production is the amount of parts produced in a duration of time.
Now convert 8 hours to minute;
60 minutes = 1hr
8 hours = 60 x 8 = 480minutes
Now:
Rate of production = = 0.47parts/minute
Now, to produce 10 parts;
It takes;
0.47 parts to be produced in 1 minute
10 parts would be produced in = 21.28s

Answer:
D
75 neutrons and 50 protons and 50 electrons
Explanation:
Atomic number represents the number of protons and it's the same number for electrons
50 protons and 50 electrons
the mass number represents the number of neutrons and protons
125-50=75 neutrons
