The answer is O2.
The ionic charge of something can be determined by it's place in the periodic table.
Answer:
9.90
Explanation:
ph= -log (H+) = -log( 1.25×10^-10)
which equals to 9.903
so the answer is 9.90
Answer:
C4H8O2
Explanation:
The molar mass of the compound we're looking for is 88.
54.5% of 88 is 4, this is how many carbons will be in the compound.
9.1% of 88 is 8, this is your hydrogens.
and 36.4% of 88 is roughly 3, however if you subtract the previous amounts to round down, you get 2; the oxygen amount.
Combine them all and you get C4H8O2
The correct response would be C. Those in the outermost shell, and of highest electron energy are the valence electrons for potassium.
