Answer:
A. manganese change from +7 to +2
Explanation:
Reduction means a gain of electrons, which means the oxidation number will go down or the charge goes down basically or become more negative charge. On the left, Mn has +7 in MnO4-. On the right, it has 2+, so it has been reduced.
Because sucrase will react with product and lower his concentration, so measurement of product concentration will not be accurate.
Sucrase activity is greater when sucrose concentration went from 2.5 to 7.5 g/l, because difference (increase<span>) between two concentration (numbers) is greater.</span>
Answer:
they are molecules with normal bonds rather than partial bonds and can occasionally be isolated.
Explanation:
In chemistry, reaction intermediates are species that are formed from reactants and are subsequently being transformed into products as the reaction progresses. In other words, reaction intermediates are species that do not appear in a balanced reaction equation but occur somewhere along the reaction mechanism of a non-elementary reaction. They are usually short lived species that possess a high amount of energy. They may or may not be isolated.
They are often molecular species with normal bonds unlike activated complexes that are sometimes hypervalent species.
