Answer:
0.0102 mole
Explanation:
Use and solve proportions for these with x as the unknown value.
I'm 99.99% sure that it is C. But what I suggest is that you google the trend of electronegativity, then double check.
It makes sense that an inner shell electron would be tougher to remove than a valence electron because the inner shell electron is closer to the positive nucleus of the atom. Seeing as an electron caries a negative charge it would be too attracted to the positive core to leave readily. Also, the inner shell electrons are constantly repelling electrons outside of it's energy level (however the reason these electrons outside innershell energy levels don't simply fly away is the charge of the positive core overcomes the smaller charges of the comparably negligible inner shell electrons, but that repulsion is still there.
<u>Answer:</u> The order follows:
<u>Explanation:</u>
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:
