Chemistry in Everyday Life Chemistry in Everyday Life Chemistry is a big part of your everyday life. You find chemistry in daily life in the foods you eat‚ the air you breathe‚ your soap‚ your emotions and literally every object you can see or touch. Here’s a look at some everyday chemistry. Elements in the Human Body Your body is made up of chemical compounds‚ which are combinations of elements. While you probably know your body is mostly water‚ which is hydrogen and oxygen. Most of the human

TOPIC 2 Metals The History of Metals * Uses of metals through history: * Copper Age (3200-2300 BCE) – copper and tin were most common metals‚ and were used for ornaments‚ weapons and tools. * Bronze Age (2300-700 BCE) – copper‚ tin and bronze were used for tools‚ weapons and transport. They produced bronze by heating copper and tin with charcoal. * Iron Age (1000 BCE – 1 CE) – iron steel and lead was used for tools‚ weapons and pipes. Iron is much harder than bronze.
