"c) Petrol and diesel are used as fuels for cars. The emissions from three similar sized cars were investigated.
The first car was the oldest, had no catalytic converter and used petrol
The other two cars were only a few years old.
One of these was fitted with a catalytic converter and used petrol and the other
car used diesel
Figure 9 shows the emissions in grams for each kilometre travelled by these three cars.

Particles vibrate in a rigid structure and do not move relative to their neighbors.

What happened to the amount of carbon dioxide in the atmosphere from 2010–2017?

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.
