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.
A kind of chemical bond in the possible reaction products that did not exist in the reactants, or a kind of chemical bond in the reactants that does not exist in the possible reaction products.
The result of a chemical reaction is a change in the properties and composition of the reactants to form one or more products with different chemical properties. This change is due to the rearrangement of atoms and the breaking and forming of chemical bonds during the reaction.
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
When hydrochloric acid is added to solid sodium hydroxide, the acid-base neutralization reaction produces water and sodium chloride (NaCl) as products. The balanced chemical equation for this reaction is: HCl + NaOH → NaCl + H2O.
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.
If the item changes form and substance chemically.
You can be sure that a chemical change has occurred if there is a change in color, formation of a precipitate, evolution of gas, or absorption/release of heat during the reaction. These are all indicative of a chemical reaction where the substances are transformed into different compounds with new chemical properties.
The only sure way to prove that a chemical reaction has occurred is to demonstrate a change in the chemical composition of the substances involved. This can be done by analyzing the reactants and products using techniques such as spectroscopy, chromatography, or mass spectrometry to identify any new substances formed. Additionally, measuring physical changes such as color, temperature, gas production, or precipitate formation can also provide evidence of a chemical reaction taking place.
You must video tape it and make sure the final result is either a physical change or a chemical change.
Yes, emission of light can be evidence of a chemical reaction. Some reactions produce light as a byproduct, a phenomenon known as chemiluminescence. This occurs when the reaction releases energy in the form of light rather than heat.
A kind of chemical bond in the possible reaction products that did not exist in the reactants, or a kind of chemical bond in the reactants that does not exist in the possible reaction products.
i am not completely sure but i think it (chemical reaction) describes when two or more atoms bond together
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.
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.
Sure, could you please provide the reaction you would like to see a balanced chemical equation for?
I think it is called a compound, but not sure
