If the initial concentrations of NO is 0.175 M. What are equilibrium concentrations of NO, N2, and O2? Read about different types, how to do double replacement reactions, and examples. a It is a precipitation reaction. However, \(Fe(OH)_3\) is insoluble, because hydroxides are insoluble (rule 6) and \(Fe\) is not one of the cations which results in an exception. These are the ions that appear on both sides of the ionic equation.If you are unsure if a precipitate will be present when writing net ionic equations, you should consult a solubility table for the compound. All replies. Label each compound (reactant or product) in the equation with a variable to represent the unknown coefficients. What will be the time taken for 6 0 % of the reaction?
