Metal and Acid Flashcards

What is the general word equation for a dilute acid reacting with a metal?: metal + acid → salt + hydrogen
What is the balanced symbol equation, with state symbols, for magnesium reacting with dilute hydrochloric acid?: $\mathrm{Mg(s) + 2HCl(aq) \rightarrow MgCl_2(aq) + H_2(g)}$
What is the balanced symbol equation, with state symbols, for zinc reacting with dilute sulfuric acid?: $\mathrm{Zn(s) + H_2SO_4(aq) \rightarrow ZnSO_4(aq) + H_2(g)}$
What is the balanced symbol equation, with state symbols, for iron reacting with dilute hydrochloric acid?: $\mathrm{Fe(s) + 2HCl(aq) \rightarrow FeCl_2(aq) + H_2(g)}$
Give two observations that can be made when a reactive metal is added to dilute acid.: Effervescence (fizzing/bubbles) and the metal disappears (gets smaller); the temperature also increases.
True or false? When zinc reacts with dilute sulfuric acid the salt formed is zinc sulfide.: False. Sulfuric acid produces sulfates, so zinc sulfate ( $\mathrm{ZnSO_4}$ ) is formed.
