llowing a series of redox reactions between a metal and an aqueous salt solution, a student recorded the following colour changes to the metal.  Q 2.4Interpret the data and describe the results for each metal and aqueous salt solution using scientific reasoning. A 3

Interpret the data and describe the results for each metal and aqueous salt solution using scientific reasoning.

Choose the answer that represents a chemical change.*1 pointDissolving salt in waterTearing up a receiptBurning your old homeworkMixing food coloring in water

Samples of three metals ‘A’, ‘B’ and ‘C’ were taken and added to the cold water, hot water and steam one by one. The results obtained have been tabulated as follows:MetalCold waterHot waterSteamABCNo reactionNo reactionReactsNo reactionReactsReactsReactsReactsReactsNow, choose the correct option(s)One/More correct answer(s)A.‘B’ can replace ‘A’ from its salt solution and ‘C’ can replace ‘A’ from its salt solutionB.‘A’, ‘B’ and ‘C’ can be Fe, Mg and Na respectivelyC.Cu can replace ‘B’ from its salt solution, but can’t replace ‘A’ from its salt solutionD.‘B’ and ‘C’ react with dilute hydrochloric acid to evolve hydrogen gas, but ‘A’ does not react with dilute hydrochloric acid

2.To place metals in order of their reactivity, metals are reacted with water or _____ ___ and see which metals react the most/least

: You should be able to write balanced chemical equations for the reactions between acids and metals, including the correct formulae for the salts formed.
