Aliter of the gas mixture at equilibrium contains 0.0045 mol of n2o4 and 0.030 mol of no2 at 10c. write the expression for the equilibrium constant (keq) and calculate the value of the constant for the reaction.

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold
