Identifying Types of Chemical Reactions Identify the reaction type for each generic chemical equation.
A+B → AB:
AB - A+B:
Hydrocarbon + O2 + CO2 + H20:
AB + CD
AD + CB:

It's either 3 or that ,,but if not than choose 4

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
