4.Write the balanced chemical equation for the reaction of concentrated nitric acid with carbon. What is the role of nitric acid in this reaction?
- A.It acts as a reducing agent, converting carbon to carbon dioxide.
- B.It acts as an oxidising agent, providing nascent oxygen to oxidise carbon to carbon dioxide.
- C.It acts as a catalyst, speeding up the reaction without being consumed.
- D.It acts as a dehydrating agent, removing water from the reaction mixture.
-
5.Some word/words are missing in the following statement. Select the option that correctly completes the statement: Aqua regia contains one part by volume of nitric acid and three parts by volume of hydrochloric acid.
- A.one part of concentrated nitric acid and three parts of concentrated hydrochloric acid
- B.one part of dilute nitric acid and three parts of dilute hydrochloric acid
- C.one part of nitric acid and three parts of sulfuric acid
- D.one part of concentrated nitric acid and three parts of dilute hydrochloric acid
