Answer:
Aluminum loses three valence shell electrons to become the aluminum ion Al+3. Nitrate is a polyatomic ion with the formula NO3 -1.
The person above me is correct I took a test on this so it’s the right answer
If he was 30.8% too low, it means that he was at 69.2% of the boiling point needed. So 50o C is 69.2% of total.
In order to know what 100% is, you can divide the number by it's percentage and then multiply it by a hundred.
So: 50/30.8=1.623
1.623*100=162.3
So the correct boiling point of the liquid he was working with in the lab is 162.3 oC
The chemical formula for acido perbromico is HBrO4 or perbromic
acid or bromate. It is an inorganic compound and an oxoacid of bromine. When an
H+, the –ate ion is –ic acid: one less O is –ous acid, ttwo less is hypo- -ous
acid and one more is per- -ic acid.
