... An inventory of atoms on each side of the equation shows that there are one N and three O on the left side of the arrow and one N and two O on the right. To balance O we must increase the number of O atoms on the right while keeping the coefficients for NO and NO2 equal. Sometimes we need to go back ...

... The following ionic compounds contain polyatomic ions (ions like NO31-, SO42- or OH1- which are made up of several atoms bonded together). Whenever a polyatomic ion needs to be doubled or tripled in a formula, parentheses must be used to avoid confusion. For example: magnesium nitrate = Mg(NO3)2 [no ...
