Answer:
The rate at which ammonia is being produced is 0.41 kg/sec.
Explanation:
Haber reaction
Volume of dinitrogen consumed in a second = 505 L
Temperature at which reaction is carried out,T= 172°C = 445.15 K
Pressure at which reaction is carried out, P = 0.88 atm
Let the moles of dinitrogen be n.
Using an Ideal gas equation:
According to reaction , 1 mol of ditnitrogen gas produces 2 moles of ammonia.
Then 12.1597 mol of dinitrogen will produce :
of ammonia
Mass of 24.3194 moles of ammonia =24.3194 mol × 17 g/mol
=413.43 g=0.41343 kg ≈ 0.41 kg
505 L of dinitrogen are consumed in 1 second to produce 0.41 kg of ammonia in 1 second. So the rate at which ammonia is being produced is 0.41 kg/sec.
Magnesium combined with chlorine.
How?
- Look at the question .Compound has -1 charge in it .Hence it contains Halogen.
- Looking at the options Option B and C contain Iodine and chlorine i.e halogens .
Now come to metals side.
- Potassium has valency 1(Look the Electronic configuration below)
Hence it will contain +1 charge which is omitted directly .
Now come to option C.
- Magnesium has charge +2(Look at EC below
Hence the compound formed is given by
Hence option C is correct.
