Step 1: Explain why the candle went off. Combustion requires oxygen. When the candle is covered by the inverted gas jar, the oxygen inside the jar is consumed by the burning candle. Once the oxygen is depleted, the candle flame extinguishes because there is no longer a reactant to sustain the combustion process. Step 2: Provide information for Mwanaisha's poster concerning the right to safety and access to information regarding flammable substances. Mwanaisha's poster should include: • Clear warning labels and hazard symbols on containers of flammable substances. • Instructions for safe storage, such as keeping them in well-ventilated areas, away from heat sources and open flames. • Guidelines for safe handling, including wearing appropriate personal protective equipment (PPE) like gloves and eye protection. • Emergency procedures in case of spills, fires, or exposure, including first aid information and contact numbers for emergency services. • Information on proper disposal methods to prevent environmental contamination and further hazards. 3 done, 2 left today.
