Answer:
25.0 mol O₂ are required in the second reaction
Explanation:
N₂ (g) + 3H₂ (g) → 2NH₃ (g)
4NH₃ (g) + 5O₂ (g) → 4NO (g) + 6 H₂O(l)
Molar ratio in first reaction is 1:2
For every mol of N₂. I make 2 moles of ammonia. If I have 20 moles of N₂, i'm going to get, 40 moles of ammonia.
In the second reaction, molar ratio between products is 4:5.
If I obtained 40 moles of ammonia in first step, let's prepare the rule of three.
4 moles of ammonia react with 5 moles of O₂
40 moles of ammonia react with ( 40.5) /4 = 25moles
<u>Methylcyclohexane:</u>
The chemical formula of the organic compound, methylcyclohexane is 
. It is branched into the group of saturated hydrocarbon.
Note: Refer the attached image for the structure of methylcyclohexane
<u>Structure of methylcyclohexane:</u>
- It is a monosubstituted cyclohexane because it has one branching through the attachment of single methyl group on one carbon of the cyclohexane ring.
- Being very toxic to the aquatic ecosystem, the methyl group of this compond in its axial position experiences a steric strain or steric crowding.
which experiment please involve a clip
Answer:
55g NH₄Cl / 100g Water
Explanation:
Solubility of a substance define the amount of solute per solvent in a saturated solution. The solution can dissolve additional solute if heated.
In the problem, as the first crystal appears at 61°C the solubility in this temperature is the concentration of the solution, that is:
2,75g NH₄Cl / 5,0g water ₓ 100 = <em>55g NH₄Cl / 100g Water</em>
