Answer:
so 0.15 moles X 22.4 dm3/mole=3.36 dm3. Next we find the moles of hexane combusted, and then the moles of CO2. Finally, we find the volume of CO2 using the fact that at STP, 1 mole of gas = 22.4 dm3.
An atom is the smallest unit of ordinary matter that forms a chemical element.
oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
Answer:
The most stable conformer would be the anti-conformer when the substituent methyl groups are farthest away from each other.
Explanation:
Isomers are chemical compounds with the same molecular formula but with different molecular structures.
Conformers are a special type of isomers that produce different structures when the substituents of a Carbon-Carbon single bond (C-C) are rotated.
In 2,3 dimethyl butane, the substituent methyl groups are located around the second and third Carbon to Carbon single bond.
To achieve a stable configuration, the methyl group substituents need to be as far apart as possible (that is, in an anti-position) to minimise repulsion.
The closer the methyl groups are to each other, the more they repel each other and the more unstable the conformer becomes.
Mass of N₂ will be formed : 50.12 g

Reaction
2 NH₃(g) + 3 CuO(s) → N₂(g) + 3 Cu(s) + 3 H₂O(g)
moles NH₃ = 3.58
ratio mol NH₃ : mol N₂ = 2 : 1
so mol N₂ :
mass N₂ (MW=28 g/mol) :
