I don't know what the problem is, but here are some rues to help you out:
- All non-zero figures are significant
- When a zero falls between non-zero digits, that zero is significant.
- When a zero falls after a decimal point, that zero is significant.
- When multiplying and dividing significant figures, the answer is limited to the number of sig figs equal to the least number of sig figs in the problem.
- When adding and subtracting, the answer is limited to the number of decimal places in the number with the least number of decimal places.
Answer:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
Explanation:
Mole percentage of nitrogen gas = 25 mole%
Mole percentage of hydrogen gas = 75 mole%
Average molecular weight of the mixture:
Rate of flow of the stream = 3000 kg/h
Mass of stream in 1 hour = 3000 kg = 3,000,000 g
Moles of stream :
Moles of nitrogen gas in 352,941.17 moles of stream be x
x = 88,235.294 mol
Mass of 8,823,529.4 mole of nitrogen gas:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
Answer:
Ionic bonds are more powerful than covalant bonds
Explanation:
This is because of their strong lattice structure formed by the attraction between metals and non-merals.
Molecules donot exhibit crystal lattices because of the covslent bonds present in between their molecules
The answer is a conjugate acid.
