Answer:
B) irreversible process
Explanation:
The process given here is irreversible.
We are asked for the ratio of ions to produce neutral KCl. When neutral potassium chloride dissociates, the reaction is KCl = K+ + Cl-. Hence, the ratio of ions from the dissociation is 1 mole potassium ion per mole chlorine ion or 1 mole chlorine ion per potassium ion.
Answer:
All carbons in the carbon skeleton contain the maximum number of hydrogen atoms
Explanation:
Saturated fats are class of compounds having all the fatty acids containing only single bonds. In other words, carbon skeleton has only single bonds.
Unsaturated compounds undergoes hydrogenation to form saturated fats.
In hydrogenation, hydrogen atoms are added to the carbon attached to double bond. After become saturated, no more hydrogen atoms can be added.
Therefore, it can be said that in saturated fats all carbons in the carbon skeleton contain the maximum number of hydrogen atoms.
D = m/v
0,7857 = m/19.26
m = 0.7857 x 19.26 = 15.132582 g
Answer:
3-methylthiophene > thiophene > benzene > 2-methylfuran
Explanation:
Primarily, five membered heterocyclic aromatic rings undergo nitration at carbon-2. This is because, nitration at carbon-2 leads to the formation of three resonance structures while attack at carbon-3 yields only two resonance structures, hence it is less stabilized.
The presence of a methyl group which donates electrons promotes the stabilization of the cation formed in the nitration of 3-methylthiophene.
2-methylfuran is the least reactive towards nitration because the 2-position has been blocked by a methyl group.
