STOICHIOMETRY:

1. Solutions of ammonium chloride and potassium hydroxide are mixed. Ammonia, potassium chloride, and water are produced. You have 1.46g of ammonium chloride in solution and 1.08g of potassium hydroxide in solution. If the experiment yields 0.406g of water, what is the percent yield?

(I don't how to start, help!)

An exothermic reaction is conducted in an insulated calorimeter filled with water. the calorimeter is then sealed so that there is no heat exchanged between the contents of the container and the surrounding air. which of the following statements is true about the reaction?

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?

Click the button that shows the correct relationship of the electron affinities of the elements sodium and phosphorus. sodium’s electron affinity value is more negative than the electron affinity value of phosphorus. phosphorus’ electron affinity value is more negative than the electron affinity value of sodium. this information cannot be determined using the periodic table. answer is b on e2020.
