predicting products of chemical reactions

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, representing the conservation of mass.

Front

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

Back

The product is zinc sulfate (ZnSO4) and hydrogen gas (H2).

Front

How do you predict the products of a single replacement reaction?

Back

In a single replacement reaction, one element replaces another in a compound. Check the reactivity series to determine if the replacement can occur.

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.

Front

What are the products of the reaction between ethylene (C2H4) and oxygen?

Back

The products are carbon dioxide (CO2) and water (H2O).

Front

What is the significance of the law of conservation of mass in chemical reactions?

Back

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

Front

What is a double replacement reaction?

Back

A double replacement reaction involves the exchange of ions between two compounds, typically resulting in the formation of a precipitate, gas, or water.

Front

What is the product of the reaction between silver nitrate (AgNO3) and potassium chloride (KCl)?

Back

The products are silver chloride (AgCl) and potassium nitrate (KNO3).

Front

What does NR stand for in a chemical reaction?

Back

NR stands for 'no reaction,' indicating that no products are formed under the given conditions.

Front

What is the role of the activity series in predicting reaction outcomes?

Back

The activity series ranks metals by their reactivity, helping to predict whether a single replacement reaction will occur.
