Explanation:
In writing the shorthand notation for an electrochemical cell, the oxidation half cell is shown on the left hand side and the reduction half cell is shown on the right hand side. The oxidation half equation reflects electron loss while the reduction half equation reflects electron gain.
Answer:
In first shell 2 electrons are present and 7 electrons are present in last shell
Explanation:
Water acts as solvent and it has no effect on the amount of the acid or the titrating agent.
<span>Also, the concentration of the titrating agent must be known exactly, the amount of solvent is less important (the more diluted it is, the more accurate is the titration).</span>

Gram is unit which is used to expressed mass of a substance. Many other units can be used to express the mass of a substance. All the units are inter changeable.
For the given values:
- <u>Option 1:</u> 1.8 micro grams
Conversion factor from Gram to micro gram
So,
- <u>Option 2:</u> 1.8 grams
All other units are expressed in this standard unit of mass and then, it will be compared.
- <u>Option 3:</u> 1.8 milligrams
Conversion factor from Gram to mili gram
So,
- <u>Option 4:</u> 1.8 kilograms
Conversion factor from Gram to mili gram
So,
Hence, the order follows:
