O2 is in fact a very pure substance. O2 is a pure substance because it's only atoms are oxygen atoms.
O2
No, O2 is not a strong electrolyte. It is a neutral molecule and does not dissociate into ions in water, which is required for a substance to be a strong electrolyte.
yes, oxygen is an example of a pure substance.a pure substance is made up of one kind of matter and it cannot be broken down into smaller parts.
Yes, it is possible for a substance to have the same empirical and molecular formula. This can occur when the substance is composed of only one type of element, such as oxygen gas (O2), where both the empirical and molecular formula are O2.
O2 is converted into H2O (water) as it accepts electrons during the process of cellular respiration.
Heating a substance can result in a chemical reaction, which usually results in a simple combustion reaction. This is because Oxygen, or O2, is added to the substance, which can dramatically alter the substance.
oxygen
Substance (fuel) + Oxygen gas → Carbon dioxide + Water Substance + O2 → CO2 + H2O
O is an atom, but O2 is a molecule.
Oxygen is a pure substance. In nature, free oxygen exists as a molecule of two oxygen atoms covalently bonded, O2.
O2 and Co2, but we breathe out the Co2 again + the O2 which is converted in more Co2
Mixture, because it is mixed with all sorts of chemicals, such as smog, and or pollen.Mixture is NOT a pure substance, because to be a pure substance, it can't be mixed with anything.
