Select the correct answer from each drop-down menu. Complete the passage about the nitrogen cycle. IF YOU POST FILE INSTEAD OF ACTUAL PHYSICAL ANSWER IM REPORTING YOU!
During nitrogen fixation, specialized bacteria living in Earth’s 1) convert nitrogen taken from the 2) onto ammonia. Another set of bacteria convert the ammonia to compounds called nitrates that plants and animals can use.

1. A. cryosphere, B. geosphere, C. atmosphere
2. A. hydrosphere, B. atmosphere, C. geosphere

1. explain hydrogen peroxide, h 2 o 2 properties and decomposition reaction. 2. describe how each of the following natural cycles plays a part in earth’s climate system. (a) the water cycle (b) the carbon cycle

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
