The number of electrons per second passing an ammeter if it reads 10 nA is 6.24 × 10⁹ electrons per second

Since our current reads 10 nA and we require the number of electrons per second passing through the ammeter, 10 nA = 1 × 10⁻⁹ C/s.

Since there are 1.602 × 10⁻¹⁹ C/electron, the number of electrons per second, n = current/electron charge

= 1 × 10⁻⁹ C/s ÷ 1.602 × 10⁻¹⁹ C/electron

= 1/1.602 × 10¹⁰ electrons  

= 0.62422 × 10¹⁰ electrons per second

= 6.2422 × 10⁹ electrons per second

≅ 6.24 × 10⁹ electrons per second

So, the number of electrons per second passing an ammeter if it reads 10 nA is 6.24 × 10⁹ electrons per second

Which of the following oils would consume the greatest number of equivalents of hydrogen when subject to catalytic hydrogenation
Murljashka [212]

Answer: Option (B) is the correct answer.

Explanation:

When a fatty acid contains high number of double bonds then its unsaturation will also be high and hence, it will consume greater number of equivalents of hydrogen.

In corn oil, there are no unsaturated sites are present.

In olive oil, there is one unsaturated site with majority of oleic acid. In olive oil, there are more than 70% of total unsaturated oils.

In lard oil, there are around 60% of unsaturated oils.

In herring oil, there are highest number of saturated fatty acids and lowest polyunsaturated acids.

Thus, we can conclude that out of the given options, olive oils would consume the greatest number of equivalents of hydrogen when subject to catalytic hydrogenation.

Temka [501]

Answer;

Iodine

Explanation;

Electron configurations are a way of keeping track of the location of the electrons around the nucleus.

Iodine is an element which belongs to the halogen family. The halogen group includes fluorine, chlorine, bromine, astatine, and iodine.

A neutral iodine atom would also have 53 electrons. Its ground state electron configuration would be:
