Question
A gas cylinder contains the gases oxygen (O2) and carbon dioxide (CO2), together in the cylinder.List any a) elements, b) compounds, and c) mixtures in the cylinder. Explain your answer.Note 1: Your answer will need to refer to atoms and chemical bonds.
Solution
a) Elements: The elements in the cylinder are Oxygen (O) and Carbon (C). These are considered elements because they are substances that consist of only one type of atom.
b) Compounds: The compounds in the cylinder are Oxygen (O2) and Carbon Dioxide (CO2). These are considered compounds because they are substances formed when two or more elements are chemically bonded together. In O2, two oxygen atoms are bonded together, and in CO2, one carbon atom is bonded with two oxygen atoms.
c) Mixtures: The mixture in the cylinder is the combination of Oxygen (O2) and Carbon Dioxide (CO2). This is considered a mixture because it is a material system made up of two or more different substances which are mixed but are not combined chemically. In this case, the O2 and CO2 are not chemically bonded together, they are simply mixed in the cylinder.
