Answer:
2NO + 4H-> N2 + 2 H2O
Explanation:
Both sides must be equal. :)
Answer:
Moles of = 6 moles
Explanation:
The reaction of and to make is:
⇒
The above reaction shows that 2 moles of Sc can react with 3 moles of to form
Mole Ratio= 2:3
For 10 moles of Sc we need:
Moles of =
Moles of =
Moles of =15 moles
So 15 moles of are required to react with 10 moles of but we have 9 moles of , it means is limiting reactant.
Moles of ScCl_3= 6 moles
Answer:
First one: group
Second one: period
Third one: number of valence electrons
Last one: increases
Answer:
NH4+
Explanation:
NH4+ is the acid and NH3 is the base, so NH4+ is the stronger acid.
