Which is true about reaction rates?
High reaction rates occur only in spontaneous reactions.
Low reaction rates occur only in nonspontaneous reactions.
Reaction rates are not dependent on high or low activation energies.
Reaction rates are not related to spontaneity.

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

Anions are negative charged ions
