How many g of mg are present in a sample that contains 8.9x10^24 atoms of mg?

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

What is the correct lewis dot structure for arsenic?

Magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. trial 1: trial 2: data mass of empty crucible with lid trial 1: 26.688 trial 2: 26.681 mass of mg metal, crucible, and lid trial 1: 26.994 trial: 2 26.985 mass of mgo, crucible, and lid trial 1: 27.188 trial 2: 27.180
