The number of hydrogen atoms that are in 7.80 moles of ammonium sulfide are 3.756 x 10^25 atoms
<u>calculation</u>
Step 1: calculate the moles of H in (NH4)2S
since there are 8 atoms of H in (NH4)2S the moles of
H = 8 x7.80 = 62.4 mole
Step 2: use of Avogadro's law constant to determine the number of H atom
that is 1 mole = 6.02 x10^23 atoms
62.4 moles=? atoms
= [ 62.4 x 6.02 x10^23]/ 1 mole= 3.756 x10^25 atoms
Answer:
Explanation:
The valency of aluminium is +3 while the valency of chlorine is -1
we will first write the half reactions
Half oxidation reaction
Now will write the complete equation-
The balanced equation would be
I'm pretty sure it's B) Mass
(99% of the total mass). 49% of carbon, 44% of oxygen, 6% of hydrogen, 0.1-0.3% of nitrogen.
