I believe the answer is c
2 moles N
2 moles H
3 moles O
<h3>Further explanation</h3>
Given
The compound is probably NH₂NO₃
Required
The number of moles
Solution
there are 2 N in NH₂NO₃, so moles N = 2moles
there are 2 H in NH₂NO₃, so moles H = 2moles
there are 3 O in NH₂NO₃, so moles O = 3 moles
Answer:
The mass of iron produced is 44.29 grams
Explanation:
Al + FeO3
Aluminium + Iron III oxide
2Al + F₂O₃ → Al₂O₃ + 2Fe
Molar mass of Al = 26.981539 g/mol
Molar mass of F₂O₃ = 159.69 g/mol
Number of moles of Aluminium = 21.4 g/26.981539 g/mol = 0.7931 moles
Number of moles of F₂O₃ = 91.3 g/159.69 g/mol = 0.572 moles
Hence, 1 mole of Al combines with 1/2 moles of F₂O₃, 0.7931 moles of Al will combine with 0.7931 × 1/2 or 0.3966 moles of F₂O₃ to produce 0.7931 moles of iron
Molar mass of iron = 55.845 g/mol
Therefore the mass of iron produced = Number of moles × Molar mass = 0.7931 × 55.845 = 44.29 grams.
Answer : The mass of water would be, 8118 kg
Explanation : Given,
Mass of = 902 kg = 902000 g
Molar mass of = 2 g/mole
The electrolysis reaction of water is:
First we have to calculate the moles of .
Now we have to calculate the moles of
From the balanced chemical reaction we conclude that,
As, 2 moles of produced from 2 moles of
So, 451000 moles of produced from 451000 moles of
Now we have to calculate the mass of
Molar mass of = 18 g/mol
Thus, the mass of water would be, 8118 kg
Answer:
1st structure - Meso
2nd structure - Chiral
3rd structure - achiral
Explanation:
In the 1st structure there is nitrogen atom bonded with 4 different groups. It is Meso compound. In the second structure a carbon atom is attached with hydroxide molecule OH and has four different environment. It is Chiral compound. In the third structure no atom have different atom or group surrounding it. Therefore it is Achiral compound.
