What is the only sure evidence for a chemical reaction?
The only way to be sure a chemical reaction or change has occurred is to test the composition of a sample before and after a change.
What is the resut of a chemical reaction?
Some chemical reactions produce heat, these are called exothermic
What is the chemical compound of a fart?
Those have nothing to do with each other. Smelling is something your body does to take in orders, and a chemical reaction is a reaction that cannot be reversed. Thus, smelling does not have anything to do with a chemical reaction.
Hydrochloric acid is added to solid NaOH after the reaction is complete NaCl dissolved in water remains what are the products of this chemical reaction?
NaCl and H2O not sure if itz rite if not then improve if it is then WOW im smart.........not....XP
Mix calcium oxide with water and then what happens?
Well, The chemical reaction when calcium is placed with water is a fizzing. It fizzes and also "produces" heat. Not sure what the chemical formula would be called however. Calcium Hydroxide possibly

The only sure evidence for a chemical reaction?
If the item changes form and substance chemically.
How can you be sure that at least one chemical change has occurred?
Evidence that a chemical reaction has taken place usually include appearance of a precipitate, change in color, or production of a gas.
What form of evidence do you need to show that a chemical reaction has taken place?
You must video tape it and make sure the final result is either a physical change or a chemical change.
Is emission of light evidence of chemical reaction?
ask a friend, family member, teacher, chemist, scientist, but i'm 37 percent sure no
Is a volcanic eruption a chemical reaction?
sure why not
What is the only sure way to prove that a chemical reaction has occurred?
Signs of chemical reactions may be: - Gas was formed - Formation of a precipitate and water - Reactants disappeared - products were made - energy is released - properties of reactant and products are different
Is a chemical reaction life science?
i am not completely sure but i think it (chemical reaction) describes when two or more atoms bond together
Why does a chemical reaction not happen immediatlety?
well I'm not really sure but i think it needs time to mix in with each other and then it will cause a chemical reaction.
What is the chemical equation for the chemical reaction?
To construct an equation for a chemical reaction, put the reactants on the left, and the products on the right, and make sure that the number of atoms of each element is the same on each side.
What is it called if two or more elements are involved in a chemical reaction?
I think it is called a compound, but not sure
What is the resut of a chemical reaction?
Some chemical reactions produce heat, these are called exothermic
