2 Science deals with Match each of the natural sciences with (i) Matter and life Ans……………………………………………………………………………… (ii) Matter and Energy Ans……………………………………………………………………………… (iii) Matter and its Reactions Ans……………………………………………………………………………… You will find the answers at the end of the module. 1.1 SAFETY IN THE LABORATORY A Chemistry laboratory is a potential source of danger with chemicals, glassware etc. Concentrated acids e.g. Nitric and Sulphuric acids are very corrosive. So are alkalis such as caustic soda (sodium hydroxide), caustic potash (potassium hydroxide). Poisonous gases can result from chemical reactions (e.g. chlorine, carbon monoxide). Flammable liquids can catch fire when exposed to naked flames. Glassware can break and cause injuries. If long hair is not tied back
