Some indicators of a chemical reaction are:
- change of color
- change of odor
- release of a gas
- change of the temperature
- change of the viscosity
- formation of a precipitate
- change of general appearance
- possible explosion
- possible chemiluminescence -formation of new compounds

What will happend if two contental plate collides?
It forms mountains
How is a precipitate evidence for a chemical reaction?
A precipitate forms when two aqueous solutions react to produce an insoluble solid. The formation of a precipitate indicates that a chemical reaction has occurred, as the reactants have undergone a change in chemical composition to produce a new substance with different physical properties. This is observable evidence of a chemical change taking place.
What is an example of the formation of a precipitate?
Formation of a precipitate is evidence of a chemical reaction.
What is most likely sign that a chemical change has happend?
The most likely signs of a chemical change include the production of gas (bubbles or odor), color change, temperature change (heat or light released), and the formation of a precipitate (a solid that forms from a solution). These indicators suggest that new substances have been created as a result of the chemical reaction.
What kind of reaction forms when a chemical bond breaks and a new bond forms?
Chemical duhhh
Which change forms a new substance?
The change were new material is produce is called chemical change.
What two forms of evidence did new England courts recognize as proof that a person was a witch?
Two forms of evidence that New England courts recognized as proof that a person was a witch were spectral evidence and effluvia.
What is a substance or molecule that forms in a chemical equations?
A substance or molecule that forms in a chemical equation is a product. Products are the result of a chemical reaction between reactants, and they are found on the right side of a chemical equation.
What is the evidence that a chemical reaction occured in silver nitrate and potassium iodide?
The evidence that a chemical reaction occurred in the reaction between silver nitrate and potassium iodide is the formation of a yellow precipitate of silver iodide. This precipitate forms due to the exchange of ions between the two reactants, resulting in the creation of a new compound with different chemical properties than the original substances.
What type of rection forms one large molecule from two or more smaller one?
A condensation reaction forms one large molecule from two or more smaller molecules. This process involves the removal of a smaller molecule, such as water, as two molecules combine to form a larger product.
Darwins opinion that living forms must be descended from extinct forms?
It was based on fossil evidence
How many forms of digestion are there?
There are two forms of digestion: mechanical and chemical digestion.
