Answer:
Fact: There’s only one letter that doesn’t appear in any U.S. state name
And that is Q
Explanation:
<span>a pure substance that can be separated into different elements by chemical means</span>
Answer:
HCl is the correct answer
Answer is: <span>the charge of the iron in this compound is +2.
Atomic mass of iron is 55,8 g/mol.
Atomic mass of chlorine is 35,5 g/mol.
If compound is FeCl, molar mass would be 55,8 </span>g/mol + 35,5 g/mol = 91,3 g/mo, that is not correct.
If compound is FeCl₂, malar mass of compound would be:
55,8 g/mol + 2·35,5 g/mol = 126,8 g/mol, that is correct.
Oxaidation number of chlorine is -1.
This is what I got. Hope it helps :)
