Calculate the equilibrium concentration of h₂. express your answer using three significant figures. use the following values in your calculations: molar mass of h₂ = 2.0159 g/mol and molar mass of br₂ = 159.81 g/mol. do not round any of your values in your calculations to the requested number of significant figures until the very last step.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
