If what you get is the same, chemically, as what you started with, then no, it's not a chemical reaction (be careful to take side effects into account: a series of reactions can yield the same molecule you started with, but make changes in other molecules in the process). If it's not chemically identical, then even if the properties are similar, it IS a chemical reaction.
If the right procedures to create that chemical process are followed, then yes. If not, then the incorrect elements have been added to a mixture.
Yes, some are not as intense as others, like Diet Coke and mentos are tougher than lemon juice and baking soda is just one of the many examples.
In different chemical reactions different gases are obtained; but this is not a general rule, because frequently the released gases are identical.
not all of them
Equilibrium occurs when the forward and backward reactions happen at the same rate
In chemical reactions, the number of atoms stays the same, yet they may recombine into different types of molecules. That is why some chemical reactions use two compounds to create a different coumpound.
A mixture
Assuming that you are referring to chemical reactions, we know that atoms are not changed by chemical reactions (except for their oxidation states). That means that all the same types of atoms are present after the reactions as were there before the reactions. The type of an atom is determined by the number of protons in its nucleus.
False! Not all chemical reactions take place at the same rate.
Yes. It is possible when the charge on the ions are different. For example the reactions will be different for Fe2+ and Fe3+
all reactions are different. therefore, different amounts of products are produced.
No. They are just two different terms that mean the same thing.
Chemical reactions in cells are faster than the same reactions outside cells.
Chemical and physical reactions breaking down the rock are different.
Elements in the same group have similar chemical properties because they have the same number of valence electrons that are used in chemical reactions.
Yes, chemical weathering involve chemical reactions.
Yes, it is a chemical change. It only takes one experience with a rotten egg to learn that they smell different that fresh eggs. When eggs and food spoil, they undergo a chemical change. The change in odor is a clue to the chemical change Chemical Reactions Chemical Changes are also called Chemical Reactions. Chemical reactions involve combining different substances. The chemical reaction produces a new substance with new and different physical and chemical properties. Matter is never destroyed or created in chemical reactions. The particles of one substance are rearranged to form a new substance. The same number of particles that exist before the reaction exist after the reaction.
You can't write a chemical equation for entire organisms; there are too many different reactions going on at the same time.
Not necessarily. Some reactions do have the same number of moles, and some do not.Examples: NaCl + AgNO3 ==> NaNO3 + AgCl same # of moles N2 + 3H2 ==> 2NH3 different # of moles
We call these enzymes but there are ones in chemical reactions which do the same but are called catalysts.
They have same atomic number
