Bromthymol blue indicator--write color last column Water directly out of tap pH =7.2 pH=5.1 pH after exhaled air is blown through a straw into water for 5 min. pH=5.8 pH after a snaishas lived in water for three days pH with 2mL of bleach pH=9.4 added to the water pH with instant coffee pH=5.0 added to the water pH after an aquatic plant pH=7.7 is grown in water for three days in bright sunlight​

Much of the general structure and physical properties of the interior of the earth are inferred from: a)deep oil and gas bore holes b)geologic investigations c)analysis of seismic waves d) study of volcanoes

What diagram shows the ionic compound of magnesium oxide

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.
