When burning sodium (Na) in oxygen (O2), you get sodium oxide (Na2O) and/or sodium peroxide (Na2O2). At high pressures, you can additionally get sodium superoxide (NaO2).
4 Na + O2 → 2 Na2O, and then partially 2 Na2O + O2 → 2 Na2O2.
Under normal conditions, approximately 20% of the mixture is Na2O2.
6 Na + 2 O2 → 2 Na2O + Na2O2

Answer:
the Glancing angle is the angle between the incident ray and plane mirror which is 90o in the given case. The angle between the direction of the incident ray and the reflected ray is the angle of deviation. Since the angle of deviation for a plane mirror is twice the glancing angle, the angle of deviation is 1800.
The concentration of a solution can be expressed in (4) <span>moles per liter~</span>
A catalyst is a chemical that increases the rate of a chemical reaction without itself being changed by the reaction. The fact that they aren't changed by participating in a reaction distinguishes catalysts from substrates, which are the reactants on which catalysts work. Enzymes catalyze biochemical reactions.
The highest value of the ion is the nucleon number. The correct option is a.
<h3>What is nucleon number?</h3>
The mass number of an element is so named because it represents the total number of protons and neutrons in the element.
The total number of protons and neutrons in an atomic nucleus is known as the mass number, also known as the atomic mass number or nucleon number. It is roughly equivalent to the atomic mass expressed in atomic mass units.
In the given ion Q+, the nucleon number has the highest value in the ion
Thus, the correct option is a.
