Question
Learning goal 1: A gas cylinder contains the gases oxygen (O2) and carbon dioxide (CO2), together in the cylinder.Identify any a) elements, b) compounds, and c) mixtures in the cylinder. Explain your answer.
Solution
a) Elements: The elements present in the cylinder are Oxygen (O) and Carbon (C). These are the basic substances that cannot be simplified or broken down into simpler substances by chemical means.
b) Compounds: The compounds present in the cylinder are Oxygen (O2) and Carbon Dioxide (CO2). A compound is a substance formed when two or more chemical 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 entire gas cylinder represents a mixture. A mixture is a material system made up of two or more different substances, which are mixed but not combined chemically. In this case, the oxygen and carbon dioxide gases are mixed together in the cylinder but they do not react with each other to form a new compound.
