Make sandwiches or molecules and test your skills with different levels of challenge.5. Balancing and Stoichiometry: a. H 2 + Cl 2 ® HCl (needs balanced) How many grams of HCl can be produced if 7.25 g of Cl 2 is reacted with an unlimited supply of H 2? b. Al + Fe 2O 3 ® Al 2O 3 + Fe (needs balanced) How many grams of Fe can be produced when 10.0g of Al is reacted with an excess (unlimited) supply of Fe 2O 3? c. Pb(CH 3COO)17.0 g/mol NH3. 3H2(g) → 2NH3(g) a. Determine to one decimal place the molar mass of each substance and express each mass in grams per mole. b. There are six different mole ratios in this system. Write out each one. 3 mol H2:1 mol N2; 2 mol NH3:1 mol N2; 2 mol NH3:3 mol H2; or their reciprocals. 7.When it comes to installing a new asphalt driveway, one of the first questions that homeowners ask is, “How much will it cost?” The answer to this question can vary significantly b...To perform a stoichiometric calculation, enter an equation of a chemical reaction and press the Start button.

Baking soda (sodium bicarbonate): about 2.5 grams per lab group. A 1 lb box can be used for at least 180 groups. Vinegar (5% acetic acid): about 60 mL per lab group. A gallon can be used for at least 60 groups. Balance.Questions & Answers. This is an exploratory lab activity that introduces the conceptual understanding of stoichiometry and limiting/excess reactants. It starts by just building sandwiches with different ingredients and then …Stoichiometry is the accounting of atoms before and after a chemical reaction. It is an expression of the Law of Mass Conservation, in that elements are neither created nor destroyed in a chemical reaction, and that mass is an intrinsic property of every element.Thus, the numbers, types of atoms, and total mass exiting a chemical reaction …This reaction produces 1 mole of fructose with a molar mass of 180.16 g/mol, for a total mass of 180.16 g. This reaction uses 6 moles of carbon dioxide (44.01 g/mol) and 6 moles of water (18.01 g/mol) for a total mass of 372.12 g. The atom economy is: 180.16g 372.12g × 100 = 48.14. Exercise 4.2.6.The coefficients for the two reactants (ingredients) are used to make a conversion factor between ham slices and pickles. Step 2: Solve.
