The grid-table indicates the level of impact that each of the five drivers have had on biodiversity over the last century. The arrows indicate the current trend of each driver on various ecosystems. One driver impacting the biodiversity in all
ecosystems is climate change. Scientists continue to predict the continued rise of global temperatures that result in
ice melt and the rise of sea level. Given this new information, predict which arrows should be changed for future
trends and how. ALL BUT ONE could apply.

The drawing represents the movement of particles in a substance. what changes of state can this substance undergo

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.

What happens to the temperature of a substance when the average kinetic energy of its particles increases?
