By chemical analysis; also a candle burn in oxygen (or in a gas containing oxygen) but not in nitrogen, argon, carbon dioxide.
oxygen gas relights a glowing splint.
Oxygen is a gas.
Oxygen gas is made up of one substance = oxygen. So oxygen gas is not a compound
Oxygen is an element. At room temperature, molecular oxygen (O2) is a gas.
When water splits, hydrogen gas and oxygen gas are formed.
identify the cause of sulfur oxide? Sulfur and oxygen chemically react with each other. Effectively, the sulfur "rusts" on contact with the oxygen
Practically all foods contain oxygen; and the first is of course water. Also the Earth atmosphere contain approx. 20 % oxygen as a gas.
Oxygen
It is most likely oxygen, as plants produce oxygen through the process of photosynthesis. Oxygen is a byproduct of the reaction that occurs when plants convert carbon dioxide and sunlight into energy.
Oxygen is a gas.
Oxygen gas is made up of one substance = oxygen. So oxygen gas is not a compound
Yes, oxygen is a colourless gas.
No, but oxygen is most common as a gas.
Oxygen IS a gas at normal temperatures and pressures
Hydrogen gas is H2. Oxygen gas is O2.
oxygen gas is heavier than hydrogen gas
Oxygen is an element. At room temperature, molecular oxygen (O2) is a gas.
At room temperature, oxygen is a gas.
