Period 6 ( 2025) Balancing & Predicting products of reactions

Front

What is a single-replacement reaction?

Back

A single-replacement reaction is a chemical reaction where one element replaces another in a compound, resulting in a new element and a new compound.

Front

What is the general form of a single-replacement reaction?

Back

A + BC → AC + B, where A is a single element and BC is a compound.

Front

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

Back

Identify if the single element can displace the element in the compound based on reactivity series.

Front

What is a double-replacement reaction?

Back

A double-replacement reaction is a chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is the general form of a double-replacement reaction?

Back

AB + CD → AD + CB, where AB and CD are compounds.

Front

What is the role of the reactivity series in predicting reactions?

Back

The reactivity series ranks metals by their ability to displace other metals from compounds; more reactive metals can replace less reactive ones.

Front

What is the balanced equation for the reaction of magnesium with aluminum hydroxide?

Back

2 Al + 3 Mg(OH)₂ → 3 Mg + 2 Al(OH)₃.

Front

What are the products of the reaction between potassium carbonate and barium chloride?

Back

K₂CO₃ + BaCl₂ → 2 KCl + BaCO₃.

Front

How do you balance a chemical equation?

Back

Adjust the coefficients of the reactants and products to ensure the same number of each type of atom on both sides of the equation.

Front

What is the product of hydrogen reacting with sulfur?

Back

H₂ + S → H₂S.
