Can you stop a chemical reaction from happening?
no... chemical reactions happen in nature however you can stop the two objects from combining
What are the special properties of enzymes?
Enzymes reduce the activation energy of a reaction. They accomplish this feat by altering the local chemical environment of the substrates while typically bringing the reactants into close proximity and even stabilizing conformers that promote reaction.
Is adding salt to water a reversible change?
No it is not reversible because the salt disolves and cannot come back !
What does the study of chemical reactions have to do with classification and prediction?
we must classify its human nature to organize. and also to predict
What is the difference between a chemical reaction and a physical one?
Physically mixing ingredients together will not change the properties of any of the ingredients. Chemical reactions make a new substance, and energy will be absorbed or given off by the reaction.?æ
Why can a chemical physical change not be reversed?
1. The chemical nature of the chemicals was modified; but reversible chemical reactions exist.2 . During a physical change the molecular structure of chemicals is not changed.
The majority of spontaneous chemical reactions in nature are?
exothermic

What is meant by the term chemical change Give 2 examples?
A chemical change is a change that imply the change of the nature of molecules. Examples: neutralization of an acidic solution, thermal decomposition and generally all chemical reactions.
Why did nature choose the specific 20 amino acids?
It is my belief that at that time when chemical reactions began nature chose the specific 20 amino acids because of the composition of the atmosphere of the early earth.
Is melting of wax reversible change?
You can easily un-melt it, i.e., wait for it to cool down and get hard again. However, the energy required for melting can't be recovered (useful energy gets converted into unusable energy), so in that sense, this process (and most processes in nature) are irreversible.
What element speeds up chemical reactions?
1) Something that speeds up a chemical reaction but that is not changed by the reactions is called a catalyst.2)An element is a pure substance (not a compound) and while some elements (such as platinum) can speed up chemical reactions (eg platinum in a car exhaust catalytic converter), by far the most common catalysts are in fact compounds not elements. These compounds are organic in nature and called enzymes.
What useful reactions do you look for?
