This blog will cover and explain the specification for Edexcel triple science course 2013 Chemistry. Hope it helps :)
Hannah do you know what the laboratory prep is, like you did with the hydrogen peroxide one in 2.18, or is it the same thing that I have to substitute in the substances to the equipment into that one?
Place calcium carbonate in a conical flask. Add hydrochloric acid in the conical flask and carbon dioxide will be released. Use downwards displacement to measure how much CO2 was made.
^ Calcium carbonate (in the form of marble chips) is added to the bottom of a conical flask, along with dilute hydrochloric acid. The HCL reacts with the calcium carbonate to produce calcium chloride, water, and carbon dioxide gas.The gas is then collected in a gas syringe or using downwards delivery. Hope that answers your question :)
eyy amar can u see this lol its shrey
