What else can I help you with?
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.
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.
What chemical change is most likely to involve bubbling or an odor?
This is a chemical reaction.
If the chemical properties of the substance have not changed has a chemical reaction occurred?
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.
Do alkanes have a smell?
Most alkanes are odorless. However, some alkanes with longer carbon chains can have a slight odor that is often described as "oily" or "hydrocarbon-like".
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.
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.
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.
What are the chemical reactions with hydrogen?
Hydrogen can participate in various chemical reactions, such as combustion with oxygen to form water, reaction with halogens to form hydrogen halides, and reaction with metals to form metal hydrides. Hydrogen can also participate in hydrogenation reactions where it adds to unsaturated compounds, such as in the hydrogenation of alkenes to alkanes.
What is an important factor in all chemical reactions?
An important factor in all chemical reactions is the type and arrangement of atoms involved. The way in which atoms interact with one another dictates the outcome of a chemical reaction.
What is the most important concept in solving stoichiometry problems?
The most important concept in solving stoichiometry problems is understanding how to use mole ratios from a balanced chemical equation to convert between different substances involved in the reaction. This allows you to determine the amounts of reactants consumed or products formed in a chemical reaction.
What do most chemical reaction do?
do not break bonds
