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.
Equimolar quantities refer to having the same number of moles of different substances in a reaction or mixture. This ensures that the reactants or components are present in stoichiometric proportions, which is important for achieving desired chemical reactions or properties. Equimolar mixtures can help in accurately predicting the outcomes of chemical reactions.
Reversible reactions reach chemical equilibrium because the forward and reverse reactions occur at the same rate, leading to a balance in the concentrations of reactants and products.
Chemical reactions involve the formation of new substances with different chemical properties, such as rusting of iron. Physical reactions involve changes in the physical state or appearance of a substance without changing its chemical composition, like melting ice.
All the elements in the periodic table of elements are electrically neutral; they do not have charges as elements, although they have the potential to engage in chemical reactions that will turn them into charged ions, in most cases. The different groups tell you what kinds of chemical reactions the elements are capable of, not what kind of charge they have.
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.
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.
Different reactions may require different catalysts. Catalysts are specific to certain reactions based on their mechanism and the chemical reactions involved. Different reactions have different activation energies and pathways, so they may require different catalysts to facilitate the reaction.
Chemical reactions in cells are faster than the same reactions outside cells.
Electrolytes produce different voltages with the same metals because the specific type of electrolyte affects the chemical reactions that occur at the electrode-electrolyte interface. The concentration and mobility of ions in the electrolyte can also influence the voltage generated. Different electrolytes may facilitate different redox reactions, leading to variations in the overall voltage produced.
Chemical and physical reactions breaking down the rock are different.
Yes, chemical weathering involve chemical reactions.
Isotopes have the same number of protons and electrons, which determines their chemical behavior. Since chemical reactions involve the transfer or sharing of electrons, isotopes with the same number of electrons will exhibit identical chemical reactions. The differences in isotopic mass do not significantly affect their chemical behavior.
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
