Why do scientist use chemical equations to explain chemical reactions?
Because it's fun
What is a purpose of a chemical equation?
A chemical equation lets humans explain a chemical reaction. When the same reaction occurs repeatedly, the equation serves to remind us of what happened in the reaction.
Explain how a catalyst aids chemical reaction to take place and identify the subsequent chemical changes in the reaction?
The role of a catalyst is to quicken the chemical reaction . On reacting, it subsequently appears as a product in the next step of the reaction.
What is the purpose of a equated?
A chemical equation lets humans explain a chemical reaction. When the same reaction occurs repeatedly, the equation serves to remind us of what happened in the reaction.
What is neutrailization explain with an example?
neutrallization is a chemical reaction of acid and alkali
Explain what a chemical change is?
a chemical change is a change which brings about a change in the chemical properties of a substance which cannot be reversed through physical means like heating or cooling.
What is the difference between an exothermic and an endothermic chemical reaction?
Nothing to explain; that is the way EXO- and ENDOthemic reactions are called by definition
Explain how wood burning in a fire place undergoes a chemical change?
Burning is an oxydation reaction so a chemical change.
Is berning methane a chemical racton explain?
Burning methane is a chemical reaction, because you are reacting it with oxygen. Work on your spelling as well.
Hydrogen peroxide breaks down into water and oxygen explain why this is a chemical reaction what are the reactants and products in the reaction?
This is considered to be a chemical reaction because it is not possible to rearrange water and oxygen to form hydrogen peroxide. This is science studied.

When water is boiled in a pot it bubbles Is this the result of a chemical reaction Explain why or why not?
It is a physical change because it is evaporation. Physical changes can be undone. If it was a chemical reaction it would be permanent like burning wood.
