Read this excerpt from Susan butcher and the Iditarod trail. the next morning seppala prepared to start again, but could find no trace of a land trail. the wind continued to blow almost at hurricane force. seppala could not even see the front of his team through this total "whiteout". it was togo who felt beneath the snow, found the trail, and started for the next relay point.

which conclusion can be formed based on the information in the excerpt?
a. Mushers and their dogs have little experience with severe winter storms.
b. mushers and their dogs are equally dependent on each other for survival.
c. mushers and their dogs depend mostly on their senses of sight on a trail.
d. mushers and their dogs often become lost during severe winter storms.

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.

Under which circumstances are kp and kc equal for the reaction aa(g)+bb(g)⇌cc(g)+dd(g)?

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
