Unit 4 - Predicting Products of Chemical Reactions

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound. For example, Zn + H2S → ZnS + H2.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds switch places, forming two new compounds. For example, FeS + HCl → H2S + FeCl2.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat. For example, 2 C6H14 + 19 O2 → 12 CO2 + 14 H2O.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product. For example, 4 Fe + 3 O2 → 2 Fe2O3.

Front

What are the products of the reaction Cu + AgNO3?

Back

The products of the reaction are Cu(NO3)2 + Ag.

Front

How do you identify a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, ensuring the law of conservation of mass is followed.

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.

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction, helping to balance the equation and reflect the proportions of reactants and products.

Front

What is the difference between reactants and products?

Back

Reactants are the starting substances in a chemical reaction, while products are the substances formed as a result of the reaction.

Front

What is an example of a balanced synthesis reaction?

Back

An example of a balanced synthesis reaction is 2 H2 + O2 → 2 H2O.
