Question
For each reaction write balanced chemical formula1) sodium metal is added to water and a gas and a base are produced
2) ethanol and methanoic acid are mixed and heated to produce an ester and water
3) a solution of tin (II) chloride is added to a solution of iron (III) sulfate to produce two new compounds one is insoluble
4) chlorine gas is bubbled through a solution of potassium iodide and a new compound and a gas is formed
5)A piece of lithium metal is placed in a container of nitrogen gas and a compound is formed
Explanation / Answer
2 Na + 2 H2O > 2 NaOH + H2 Where in an elemental Na is added to Water and produces NaOH and hydrogen gas. Freshly cut sodium has a metallic sheen. Within a few minutes, water in the air causes a layer of sodium hydroxide to develop on exposed surfaces. The reaction is strongly exothermic and the heat transferred to the local environment ignites the hydrogen that is produced. The hydrogen burns with a bright flame. Answer
