Is burning coal an example of a physical reaction or a chemical reaction?
Chemical. It is called combustion.
How is burning an example of a chemical property?
Burning is an example of a chemical property because it can only be observed during a chemical reaction called combustion.
What is a basic example of a chemical reaction?
Burning paper.
What type of chemical reaction is a flaming flask?
This is an example of hydrogen burning.
What is paper burning an example of?
A chemical reaction, and also a reaction in general.

If a candle burning example of?
Candle burning is the process called oxidation. This is, it's the reaction that takes place when a gaseous material reacts with oxygen, the wax needs to change to gaseous state for the reaction to take place.
What is an example of a chemical reaction that occurs quickly?
Ex.: burning of methane, reaction of calcium carbonate with acetic acid, reaction of sodium with water.
What kind of chemical reaction is an exothermic reaction?
Exothermic reaction: reaction with release of heat; for example burning of organic materials (oxydation of carbon) is a typical exothermic reaction.
Is the burning of phosphorus physical or chemical change?
Burning of anything is a chemical change. Combustion (burning) is a chemical reaction; it is simply where oxygen is added to, for example, an element, and turns it into an oxide. Burning phosphorus would result in phosphorus oxide. P + O2 --> P4010
How does changing the amounts of reactants in a chemical reaction change the chemical compositions of the products?
Yes, it is possible; for example complete or not complete burning.
Which is an exothermic chemical reaction?
An exothermic reaction is a reaction with release of heat. As an example the burning reaction of methane: CH4 + 2 O2 ------→ CO2 + 2 H2O
