Answer:
6 moles of electrons
Explanation:
Let us consider the species NO3− and ClO−. The NO3− is oxidized to NO the oxidation number of nitrogen is decreased from +5 to +2.
The oxidation number of chlorine is increased from +1 to +3. This implies that six electrons were transferred in the balanced reaction equation shown in the question. Hence the answer.
Answer:
Chromosome is basically made of DNA and proteins.
Explanation:
Chromosomes contain thread like structure present inside the nucleus of the cell.Chromosome is generally made of DNA and proteins(Histone proteins).
The DNA is wrapped around the basic protein histone to provide support the chromosome structure.
The wrapping of DNA around the histone proteins helps in the formation of nucleosome which helps in the packing of DNA inside the chromosome.
V1M1 = V2M2
<span>V1 × 2.5 = 1 × 0.75,
so V1 = 0.75/2.5
= 0.3 </span>
Answer:
53.8 L
Explanation:
Ideal gas law
PV=nRT
must be for volume so we arrange to V=nRT/P
V= (4.8)(8.31)(297)/220
