Reducing activation energy select one: a. is accomplished by the action of catalysts on reactants. b. requires higher temperatures than those found within cells. c. is a violation of the laws of nature. d. occurs only when reactants are quickly added to the reaction mixture.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
