Investigation 6 Enriched Chemistry Review

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: 3KOH + H3PO4 → K3PO4 + 3H2O.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. Example: 4Si + S8 → 2Si2S4.

Front

What does it mean for a chemical equation to be balanced?

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 are the balancing coefficients for the reaction: FeCl3 + Ca(OH)2 → Fe(OH)3 + CaCl2?

Back

The balancing coefficients are 2,3 → 2,3.

Front

What is the result of the reaction Br2 + NaF?

Back

No reaction will occur because bromine is less reactive than fluorine.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: 2H2O → 2H2 + O2.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: Zn + CuSO4 → ZnSO4 + Cu.

Front

What is the difference between a reactant and a product?

Back

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

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.
