I feel like it is important, because it is always nice to learn about
new things and keep your mind open, to expand your knowledge.
I hope this helps ^-^
Answer:
1.0625 g
Explanation:
Number of moles in 5g of NH4NO3 = 5.0g/80g/mol = 0.0625 moles
Again the balanced reaction equation is;
NH3 + HNO3 → NH4NO3
So,
1 mole of NH3 yields 1 mole of NH4NO3
x moles of NH3 yields 0.0625 moles of NH4NO3
x = 0.0625 moles of NH3
Mass of NH3 = number of moles * molar mass
Mass of NH3 = 0.0625 moles * 17g/mol
Mass of NH3 = 1.0625 g
Halogens (atoms with 7 valence electrons) and Hydrogen
or generally, atoms with their shells almost full
6. Put a 2 before H2O, and a 4 before HF
7. Just put a 2 before HCI
8. I can't seem to figure this one out...sorry. I can keep trying if you want tho...
9. Put a 2 before HNO3 and a 3 in front of O2
10. I think you just put a 2 in front of H2O.
I tried my best. I hope I got at least one right...I started this stuff yesterday..good luck
