If the burning of magnesium to form magnesium oxide is incomplete, there will still br some elemental magnesium available to be burned (ie combined with oxygen) and so there will be a measureable amount of mass of magnesium left. Also, the amount of oxygen required to combine with the outstanding mass of magnesium could also be determined.

Go for it!

Answer:
ClO- = bronsted Lowry base
H2PO4- =Bronsted Lowry base
Explanation:
ClO- = is bronsted Lowry base because it accepts a proton in the reaction
H2PO4- =Bronsted Lowry base because it's a proton donor in the reaction
Answer:
If an atom has the same number of electrons as protons, it is a neutral atom.
Explanation:
1/8=(1/2)^3 and the half life of radon is 3.8days
Half life is the time it takes for half of any amount of a radioactive substance to decay into something else.
Therefore for a sample of radon to decay to 1/8 of its original amount, it would take 3 x 3.8days=11.4 days
