1.0 x 10^-3 x 65.38 = 0.0654 g Zn
Answer:
16.8128 grams of sodium azide is needed
Explanation:
2NaN3 = 2Na + 3N2
molar mass of NaN3 =

molar mass of N2

moles of N2 =
moles=mass/R.F.M
16.55÷42 = 0.3940
mole ratio=
2NaN3 : 3N2
3 = 0.3940
2=?

Mass of sodium azide =64×0.2627
=16.8126
Answer:
<h2><u>Of moles of NH4NO3 = 16/80 i.e. 0.2 moles of Ammonium Nitrate. 1 molecule of NH4NO3 contains 1 atom of N. Hence, 1 mole of NH4NO3 would contain 1 mole of Nitrogen atoms and therefore 0.2 moles of NH4NO3 should contain 0.2 moles of Nitrogen atoms</u>.</h2>
Explanation:
C is incorrect. I has 21 PROTONS in its nucleus. Not neutrons.
