Balancing Chemical Equation Quiz

15 Questions

Quiz Description

This particular quiz of the gcse chemistry quiz is basically all about the fundamentals of science which is chemical reactions and how they are balanced. The quiz is composed of 15 questions which have been set to cover a majority of what is done in the topic at the gcse level. Each question has four possible answers but just one and only one of these options is correct. 

Chemical reactions are simply changes made to the arrangement of the atoms and molecules found in materials and they are all around us in fireworks and explosions, cooking, etc chemical reactions, involving the combination of two or more compounds known as the reactants to form other compounds which are known as the product(s). 

Balancing these equations comes into handy when we wish to know the number of reactants that will come together to form the product. It is important to note that the balancing of chemical equations is done using positive whole numbers.

You can now go ahead and test your knowledge with our quizzes.
