At a certain temperature, the equilibrium constant, kc, for this reaction is 53.3 at this temp, 0.3000 mol of h2 and 0.300 mol of i2 were placed in a 1l container to react. what concentration of hi is present at equilibrium? h2+i2< -> 2hi

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. type your answer here. (score for question 4: of 5 points) make a general statement about the reactivity of the metals in this experiment. type your answer here.
