Unit 3: Chemical Reactions Review

Front

What are the products of a combustion reaction?

Back

Carbon dioxide and water.

Front

What is the balanced equation for the reaction of BF3 and Li2SO3?

Back

2 BF3 + 3 Li2SO3 → B2(SO3)3 + 6 LiF.

Front

How do you calculate the number of moles in a solution?

Back

Moles = Molarity (M) × Volume (L).

Front

What are the products of the double replacement reaction AgNO3 + KCl?

Back

AgCl + KNO3.

Front

What is the molar mass of aluminum chloride (AlCl3)?

Back

133.341 g/mol.

Front

Define a combustion reaction.

Back

A chemical reaction that occurs when a substance combines with oxygen, producing heat and light.

Front

What is the formula for calculating molarity?

Back

Molarity (M) = Moles of solute / Volume of solution in liters.

Front

What is a double replacement reaction?

Back

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

Front

What is the significance of balancing chemical equations?

Back

It ensures the law of conservation of mass is followed, meaning the number of atoms remains the same before and after the reaction.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst speeds up a reaction without being consumed in the process.
