In a lab experiment, 6.9 g of Mg reacts with sulfur to form 16.0 g of magnesium sulfide. (a) Use the equation below to calculate the percentage by mass of Mg in magnesium sulfide. % X component = amount of component x.. total amount 4.9 % (b) How many grams of sulfur reacted? 49 How do you know? O law of constant composition O law of definite proportions O law of multiple proportions O law of conservation of mass

The correct formula form sometimes in this experimenti 0.9 Mg to 1.0 0) In that case, it mean sium oxide is MgO, a 1.0 to 1.0 ratio. But periment the ratio of Mg to O comes out too low. (Example se, it means that there was too much oxygen relative 1 f magnesium. At other times it comes out that the ratio is too large A vould be: 1.2 to 1.0 (Mg to O). In such a case it must...

Mass of Magnesium strip Use the length of your magnesium strip and the mass per m provided by your TA to calculate the mass of your magnesium strip. Make sure to convert so that your units match! Mass of magnesium strip Moles of magnesium used Convert the mass of each magnesium strip into moles using the molar mass. Moles of magnesium Moles of hydrogen produced (n) Use the mole ratio from the balanced chemical equation to convert the moles magnesium...

Model 4: Using Moles of Limiting Reagent in Stoichiometry The above pictures are not realistic because they involve so very few molecules. In a "real-world" sample, you are likely to have on the order of 10 molecules. Consider the following: Suppose you have a reaction vessel initially containing 13.5 moles of sulfur dioxide and 11.2 moles of oxygen mol SO, required to react with all O2 = 11.2 mol O2 x 2 mol SO 22.4 mol SO, 1 mol O2...

1. Balance the following reaction equation. Note: in Organic Chemistry, a standard balanced reaction equation not only balances all the elements on the left vs. the right, but also shows molecular structures. Formulas such as "C.H.O." are normally not used, because they don't identify a specific isomer. conc. HCI conc. HCI X 2. Complete the following table, using your actual measured...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
