What is a single displacement reaction?

Back

A single displacement reaction is a chemical reaction where one element displaces another in a compound, resulting in a new element and a new compound. Example: \( A + BC \rightarrow AC + B \)

Front

What is a double displacement reaction?

Back

A double displacement reaction is a chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: \( AB + CD \rightarrow AD + CB \)

Front

What is the general form of a combustion reaction?

Back

A combustion reaction typically involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water. General form: \( C_xH_y + O_2 \rightarrow CO_2 + H_2O \)

Front

What is the product of the reaction between zinc and hydrochloric acid?

Back

The reaction produces zinc chloride and hydrogen gas: \( Zn + 2HCl \rightarrow ZnCl_2 + H_2 \)

Front

What is the product of the reaction between calcium and hydrochloric acid?

Back

The reaction produces calcium chloride and hydrogen gas: \( Ca + 2HCl \rightarrow CaCl_2 + H_2 \)

Front

What is the result of mixing potassium carbonate and barium nitrate in aqueous solution?

Back

The reaction produces potassium nitrate and barium carbonate: \( K_2CO_3(aq) + Ba(NO_3)_2(aq) \rightarrow 2KNO_3(aq) + BaCO_3(s) \)

Front

What is the product of the reaction between aluminum sulfate and sodium hydroxide?

Back

The reaction produces aluminum hydroxide and sodium sulfate: \( Al_2(SO_4)_3 + 6NaOH \rightarrow 2Al(OH)_3 + 3Na_2SO_4 \)

Front

What is the product of the reaction between silver nitrate and potassium chloride?

Back

The reaction produces silver chloride and potassium nitrate: \( AgNO_3 + KCl \rightarrow AgCl + KNO_3 \)

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It lowers the activation energy required for the reaction.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. The total mass of reactants equals the total mass of products.
