What else can I help you with?
What are substances that change when the become involved in chemical reaction?
Rust is formed by the chemical reaction of oxygen to iron. This process is called oxidation and occurs when ever iron (or some other materials) are exposed to oxygen. The result makes a new substance: rust.
What is the law of indestructibility of matter?
No weight is ever gained or lost in a chemical reaction.
Is a mixture ever evidence of a chemical reaction?
Just because one has mixed chemicals together doesn't mean one will get a chemical reaction. The two chemicals could stay neutral when mixed. So, no just because a chemical is mixed it doesn't have to have a reaction.
Would it ever be true that matter and energy may be created or destroyed in a chemical reaction?
No, the law of conservation of matter and energy states that matter and energy cannot be created or destroyed in a chemical reaction. They can only be converted from one form to another.
Have you ever wondered how energy participates in chemical reactions?
I wonder about a lot of things, yes.
What is a chemical reagent?
Reagent bottle is a bottle designed to contain chemical reagents. Bottles are made generally from glass, plastic coated glass, polyethylene. The volumes are extremely variable, from 1 mL to liters.
What is the slowest rate of reaction ever recorded?
The slowest rate of reaction ever recorded is called a "first-order reaction," which is a type of chemical reaction where the concentration of reactants decreases exponentially over time. These reactions can take an extremely long time to complete, with some reactions having half-lives of millions or even billions of years.
What chemical reaction takes place when bleaching a stain?
Bleaching stains typically involves the chemical reaction of the bleach (usually chlorine-based compounds like sodium hypochlorite) breaking down the chromophores in the stain molecules. This process disrupts the bonds that give the stains their color, effectively decolorizing them.
How ever many protons there are in an object is there that many neutrons?
Neutrons = Rounded Atomic Mass - Amount of Protons
Do the number of protons in a specific atom ever change?
no. because if the number of protons changes, then the element changes
Does the number of protons of carbon ever change?
No, the number of protons in an atom of a specific element like carbon does not change. Carbon always has 6 protons.
Can two elements be combined chemically to make another element?
they are 2 completely different substances usually- If they combine they make a compound or a molecule. this is 2 substances together. Example- H2O=Oxygen+2 Hydrogin atoms(water)
