elements like carbon ,nitrogen, sulfur and oxygen and etc are most likely to form covalent bonds
Centrifugation is used to separate the suspended particles in solution.
<u>Explanation:</u>
- The method of centrifugal action commonly referred to as "Centrifugation" is majorly used to effectively separate the suspended particles from the solution by means of rotating the sample at the maximum speed.
- When the samples gets rotated at the maximum speed the suspended particles settles down at the bottom and it can be filtered using the filter paper,thus resulting in the separation of suspended particles in the solution.
- However this techniques cannot be used for the substances dissolved in solution.
You need the unit of g however you must convert to moles before you can use the mole ratio to find the moles of iron, you used the molar mass of iron to find the grams of iron. since F e 2 o 3
The answer is: "second order" .

For #1, I'd say it's "It will usually bond to multiple atoms which can provide a total of 4 additional electrons."
2. Ionic (I'm quite certain because anions/cations (-1 & +1) are Ionic from what I recall, if that's true it's Ionic.
3. "comparison of the associated families to which the elements belong" and
"the difference in electronegativities" are what I would choose, as I mentioned in a comment earlier.
If I'm wrong let me know, but I am at least 80% sure that these responses are correct from what I remember in Chemistry.
