The correct answer is Oxyanion Nitrite. Oxyanion is referred to as an ion which contains one or more oxygen atoms that are bonded to another chemical element. It has a generic formula of <span>A. </span>x<span>O </span>z− <span>y, wherein A, stands for a chemical element, while O, stands for an Oxygen atom</span>
Answer:
Explanation:
Personal opinion/interpretation are usually firsthand explanation to a phenomenon or problem set. They are usually drawn from logical reasoning and deduction about some event. Most times, they are non-scientific in nature in that they are non-methodical and do not rely on the critical thinking precepts scientific studies are hinged on.
Verified observations are usually drawn from carefully planned experiments. From the results of the experiment, critical decisions can be made.
12.01 amu
Work:
(12.000 × .9889) + (13.003 × .0111) = 12.01
- turn the precents into decimals
=
= 0.134 mol
mol of oxygen:
ratio of
= 2 : 15
= 1 : 7.5
: . mol of
= 0.134mol * 7.5
= 1.01 mol
Mass of Oxygen = mol * Mr
= 1.01 mol * (16*2) g/mol
= 32.22g
Note: Mr is molar mass
