Answer:
on the surface of the cathode
Number one would be Decades
Nitrogen and oxygen do not react at ambient temperature. At high temperatures they have endothermic reactions and produces various oxides of nitrogen.
Explanation:
The difference between nitrogen and oxygen is the nitrogen has seven protons and seven electrons surrounding the nucleus. Whereas the oxygen has eight protons and electrons.
The atoms combines with one another to form molecules. The nitrogen is a inert, colorless gas with no smell or taste, its harmless to human beings.
The oxygen and nitrogen are abundant gases in the atmosphere and have similar physical properties. The oxygen (O2) is twice as soluble in water as nitrogen (N2).
B. Are produced only by living things
The appropriate answer is they decrease the potential energy difference between reactant and product. They do this by bringing products and reactants together at the active site on the enzyme molecule. Enzymes are biological catalysts. They increase the rate of a chemical reaction without being used up in the reaction itself. So one molecule of an enzyme is used many times to catalyze the reaction of other molecules.
