4. Magnesium is the limiting reactant in this experiment. Calculate the theoretical yield of MgO for each trial.

• Trial 1:

• Trial 2:

5. Determine the percent yield of MgO for your experiment for each trial.

• Trial 1:

• Trial 2:

6. Determine the average percent yield of MgO for the two trials.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

ugh fiel iente of insistí is did kiwis jaj

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
