One method to produce nitrogen in the lab is to react ammonia with copper (ii) oxide: nh3(
g. + cuo(s) cu(s) + h2o(l) + n2(
g. after using 40.0 grams of nh3, 15.5 grams of n2 are produced. what is the percent yield of nitrogen in the reaction?

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.

At 20°c, a sample of h2o liquid and a sample of co2 gas each have the same average kinetic energy. why is one a liquid and the other a gas at this temperature?

The number of moles of a given mass of a substance can be found without knowing its molecular formula or molar mass. true false
