Predicting Products and Types of Reactions

What is the general form of a combustion reaction?

• Hydrocarbon + O2 ➔ CO2 + H2O

• Hydrocarbon + O2 ➔ CO + H2O

• Hydrocarbon + O2 ➔ H2 + O2

• Hydrocarbon + O2 ➔ C + H2O

What is a single replacement reaction?

• A chemical reaction where one element replaces another element in a compound.

• A reaction where two compounds exchange ions to form two new compounds.

• A reaction that involves the breaking down of a compound into simpler substances.

• A reaction that occurs when two elements combine to form a compound.

How do you determine the charge of an ion using the criss-cross method?

• You add the charges of the ions to determine the subscripts in the compound.

• You swap the charges of the ions to determine the subscripts in the compound.

• You multiply the charges of the ions to determine the subscripts in the compound.

• You ignore the charges and use the atomic numbers to determine the subscripts in the compound.

What is the charge of Iron in Fe3(PO4)2?

• +1

• +2

• +3

• +4

What is the general form of a single replacement reaction?

• A + BC ➔ AC + B, where A replaces B in the compound.

• A + B ➔ AB, where A and B combine to form a compound.

• AB + C ➔ AC + B, where C replaces A in the compound.

• A + B ➔ A + B, where no reaction occurs.

What is the general form of a double replacement reaction?

• AB + CD ➔ AD + CB, where A and C are cations and B and D are anions.

• AB + CD ➔ AC + BD, where A and B are cations and C and D are anions.

• AB + CD ➔ A + B + C + D, where A, B, C, and D are all ions.

• A + B ➔ AB, where A and B are reactants that form a compound.

What is a double replacement reaction?

• A chemical reaction where two compounds exchange ions or bonds to form two new compounds.

• A reaction where one element replaces another in a compound.

• A reaction that involves the breaking of chemical bonds without forming new compounds.

• A reaction that occurs only in gaseous states.

What is the purpose of a solubility chart in predicting reactions?

• It helps determine whether a solid precipitate will form in a double replacement reaction.

• It indicates the temperature at which a solution will boil.

• It shows the pH levels of various solutions.

• It lists the molecular weights of different compounds.

What is the significance of balancing chemical equations?

• It ensures that the law of conservation of mass is followed, meaning the number of atoms of each element is the same on both sides of the equation.

• It allows for the prediction of the products of a chemical reaction.

• It simplifies the chemical equation for easier understanding.

• It helps in determining the temperature at which a reaction occurs.

What is a synthesis reaction?

• A chemical reaction where two or more simple substances combine to form a more complex product.

• A reaction where a single compound breaks down into two or more simpler substances.

• A reaction that involves the exchange of ions between two compounds.

• A reaction that occurs only in the presence of a catalyst.
