How many electrons are present in a benzene?
Expert
30 electrons are in a benzene. This comprises 6 hydrogen electrons and 24 carbon electrons. In this 12 electrons shared among C and H, and 18 among C and C. (6 electrons in ring, 6 in down ring and 6 among C and C).
Relative humidity is the ratio of the partial pressure of water in air to the partial pressure of water in air saturated with water at the same temperature, stated as a percentage: Relative = Q : What are heterogenous catalysis? Give When the catalyst exists in a different phase than that of reactants, it is said to be heterogeneous catalyst, and the catalysis is called heterogeneous catalysis. For example, SO2 can be oxidized to SO3
