Answer:
a) No. of moles of hydrogen needed = 5.4 mol
b) Grams of ammonia produced = 27.2 g
Explanation:

a)
No. of moles of nitrogen = 1.80 mol
1 mole of nitrogen reacts with 3 moles of hydrogen
1.80 moles of nitrogen will react with
= 1.80 × 3 = 5.4 moles of hydrogen
b)
No. of moles of hydrogen = 2.4 mol
It is given that nitrogen is present in sufficient amount.
3 moles of hydrogen produce 2 moles of 
2.4 moles of hydrogen will produce
= 
Molar mass of ammonia = 17 g/mol
Mass in gram = No. of moles × Molar mass
Mass of ammonia in g = 1.6 × 17
= 27.2 g
Answer:
None of the above.
Explanation:
The limiting factor of this is the chlorine. You only have 2 moles of chlorine.
2Na + Cl_2 ==> 2*NaCl
The equation tells you that for every mol of Cl2 that you have, you require 2 moles of Na and you get 2 moles of NaCl
So what that means is that if you have 2 mols of Cl2, you need just 4 moles of Na, and you will get 4 mols of NaCl
Since 4 is not one of your choices, the answer is none of the above
Answer:
ZnCO3 + 2HClO4 = Zn(ClO4)2 + CO2 + H2O
Explanation:
ZnCO3 + 2HClO4 = Zn(ClO4)2 + H2CO3
ZnCO3 + 2HClO4 = Zn(ClO4)2 + CO2 + H2O
