Scientists believe continental drift over Earth’s geological history has had a significant impact on Earth’s cycles of warmer and cooler climates. Which statement describes a characteristic of Earth’s continents that is MOST likely to cause changes in global climate when continents drift? A. Continental plate depth determines its specific heat.
B. The location of the continent affects its surface reflectivity
C. The temperature of a continent is affected by its nearest ocean.
D. Continental drift absorbs large amounts of kinetic energy.

Balance this equation: n2 + h2 > nh3, write the following molar ratios: n2 / n2 / nh3 h2 /

Chen drew a diagram to compare the ways in which different organisms obtain nitrogen. which label belongs to the area marked z?

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.
