Three metals, X, Y and Z were put into water. The reactions are shown below. Use the diagrams to put metals X, Y and Z in order of reactivity, starting with the most reactive.ExpandA:XZGB:YZXC:ZXYD:XZY

When a metal X is treated with cold water, it gives a basic salt Y with molecular formulaXOH (Molecular mass = 40) and liberates a gas Z which easily catches fire. Identify X, Y andZ and also write the reaction involved.

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

8. Write word and balanced chemical equations for the reactions between:a sodium and waterb magnesium and steamc calcium and oxygend bromine and potassium iodide solutione zinc and copper sulfate solution.

Zinc atoms can be converted to Zn2+ ions by I     adding the zinc to hydrochloric acid II    heating the zinc in air III   adding the zinc to cold water AI only BI and II only CII and III only DI , II and III
