Reactions of Acids Flashcards

All 6 cards in this deck

What is the general word equation for an acid reacting with a metal?: metal + acid → salt + hydrogen
What is the general word equation for an acid reacting with a metal carbonate?: metal carbonate + acid → metal salt + carbon dioxide + water
What is the general word equation for an acid reacting with a metal oxide or a metal hydroxide?: metal oxide (or hydroxide) + acid → metal salt + water
Which acid is used to make chloride salts, and which acids make sulfates and nitrates?: Hydrochloric acid makes chlorides; sulfuric acid makes sulfates; nitric acid makes nitrates.
True or false? Fizzing is seen when a metal oxide reacts with dilute acid.: False. No gas is produced; the solid just disappears/dissolves. Fizzing happens with metals or carbonates.
True or false? In a balanced symbol equation, hydrogen gas can be written as $2H$ .: False. Hydrogen gas is made of molecules, so it is written $H_2$ ; $2H$ means two separate hydrogen atoms.
