Chemical Reaction Quizzes & Trivia

Chemical reactions are part of our daily lives. From cooking in the kitchen, to driving a car, these reactions are commonplace. In a chemical reaction, the molecules of one substance break apart and join together with those of another substance to create a different compound (combination of molecules).

Many chemical reactions are non-reversible changes .You cannot turn a baked cake back into its raw ingredients. Some chemical reactions can be reversed, and re-formed into the original substances. These are reversible changes.

If you fancy one reaction or another, then you will most surely enjoy the questions of these quizzes: “The smallest particle of gold which still retains its characteristics is?”, “An atom containing 19 protons, 20 neutrons, and 19 electrons has a mass number of?”, and “What does all matter have?”.

Why is it exothermic it has a positive energy energy is getting absorbed so therefore shouldn't the energy level increase?
What are properties that do depend on the amount of matter present called?
C is the answer to this question. An extensive property is one of the properties of matter that will change depending on the amount of matter that it will be exposed to. Mass is one example of an extensive property. For example, you are going to plac
What is an example of a true solution?
In science, a true solution deals with the type of mixture and how it is dissolved. Also, it also has to comply with the measurements of the particle size. Specifically, a true solution’s particles can’t be larger than one nanometer. It a
