Answer:
5.71 x 1021 (C)
Explanation:
Because if the numbers are over 5 then u round to the next number. So since 6 is bigger than 5 that means is gonna round up so it will be 7 and so. I hope that helps a bit
Answer:
1) S2N
2)ClI
Explanation:
A chemical formula shows the relative ratio of atoms present in a compound. When we write a chemical formula, we have an idea of the ratio in which atoms combine in the compound of interest. This is a great clue when we are attempting to elucidate the structure of the compound.
For hexasulphur mononitride,the formula of the compound must be S6N3, this reduced to lowest terms to give S2N.
Similarly, the formula for chlorine monoiodide is ClI as shown in the answer above.
It would be +7 oxidation number.
[All compounds are zero]
Al is in group III [ or 13 depending on the system ] so the oxidation state is 3.
You have 12 O at -2 each for-24. That leaves you at -24+3=-21. So, 3 Cl atoms must be +21 to balance the -21 there which makes +21/3 or +7 for each Cl.
It is equal to amount of thymine
