Will mark brainliest in the diagram, the black line represents the concentration of a reactant and the green line represents the concentration of a product.

which statement best describes the reaction rate?

the reactants maintain an constant concentration in the first half of the reaction.

at the end of the reaction, both product and reactants are of an equal concentration.

the product maintains an constant concentration in the first half of the reaction.

at the end of the reaction, both product and reactants are of a constant concentration.

Which statement best explains the relationship between an area is geography and the temperature of its surface water

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.
