To begin the experiment, 1.5g of methane ch4 is burned in a bomb calorimeter containing 1,000 grams of water. the initial temperature of water is 25°c. the specific heat of water is 4.184 j/g°c. the heat capacity of the calorimeter is 695 j/°c . after the reaction the final temperature of the water is 37°c. using the formula qcal =ccal • δt, calculate the heat absorbed by the calorimeter. show work.

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally

Scientific evidence tells us that the cause of earths four season is the tilt of earth as it revolves around the sun. the student is instructed to illustrate this information in a science notebook. how will the student illiterate winter in the northern hemisphere?

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.
