A chemical reaction is the change that takes place when two or more substances?
interact
Is decomposition reaction a chemical reaction?
It depends on the nature of the decomposition. if you are talking about biodegradeability in a substance, then no, its decomposition is mainly due to bacteria that will break down the various particles in the substance ("eat" them). There are, however certain chemical reactions which take place within the bacteria as the substance is being broken down, (much like those that happen in the human body) and the possibility of there being other products in the vicinity which may react to the substance (and degrade it) is always present. It could be said that decomposition is therefore a chemical reaction (or rather a series thereof), but with biodegradeability in mind it is not generally thought of as such.
One of 5 things have to happen for a chemical reaction to take place?
the requiredactivation energy is the basic factor for a reaction to start.

What would you expect to happen if you mixed argon and sodium together?
Since argon is a noble gas, I wouldn't expect much to happen; specifically, I wouldn't expect any chemical reaction.
Explain what it means for a reaction to be endothermic and what would happen to the temperature recorded by a thermometer in an endothermic reaction?
An endothermic reaction absorbs heat energy from the system. In an endothermic reaction a thermometer measuring the reactants and products would register a decrease in temperature.
What take place during a chemical reaction?
During a chemical reaction the breaking of the older bonds and formation of the new bonds take place.
