Is burning of gasoline in the car a chemical change?
Gasoline burning is an oxidation reaction, a reaction with oxygen.So, burning is a chemical change. And fire was the most important discovery of human beings.
In what kind of reaction can the products form the reactants?
The type reaction that changes the reactants into products is called a chemical reaction. Most chemical reactions can run forward or backward.
Is charcoal burning in a grill physical or chemical?
Its a chemical change because the properties of charcoal are changing when fire makes contact with it. It is realising energy and that is one of the most important signs to know if it is a chemical reaction.
Which part of a chemical reaction is most changed by enzyme activity?
Reaction equilibrium
What chemical change is most likely to involve bubbling or an odor?
This is a chemical reaction.
What is the most important chemical reaction of all?
Photosynthesis
What is needed to begin a chemical reaction?
The most important: to have the reactants !
What is the most important sign that a chemical reaction is occuring?
The most important sign is when you smell an odor . when you began to smell and odor that is a automatic chemical change.

What is the most important characteristic of a nuclear reaction?
Nuclear reactions involve the reaction of nuclei and does not involve transfer of electron as in regular chemical reactions.
In what kind of reaction can the products form the reactants?
The type reaction that changes the reactants into products is called a chemical reaction. Most chemical reactions can run forward or backward.
What do most chemical reaction do?
do not break bonds
What change will most likely increase the rate of a chemical reaction?
Factors which can increase the rate of a chemical reaction:- temperature- pressure- concentration of reactants- stirring- if solids are involved the dimension of particles is important- the type of reaction- the order of reaction- presence of catalysts- influence of external factorsetc.

What is the biggest chemical reaction from homemade stuff?
How big is the biggest chemical reaction depends on what you mean by "big." Is it a reaction with the most spectacular result, the most ingredients, the most steps, or the most of something else? One suggestion was making Luminol, which is an 8 step reaction, and each step is a chemical reaction its self. Look at NurdRage video on how to make it on YouTube
