If 100.0g of nitrogen gas (N2) is reacted with 100.0g of hydrogen gas (H2) what is the limiting and excess reactants?
Hint: convert grams to moles for each reactant and then convert to moles of NH3. You need your balanced equation from answer 1 to determine the mole relationship between each reactant and the product NH3. Use the periodic table to determine the molar mass of all chemical formulas. Fill in the “?” Blanks below to show your work.
Please please please fill in the blanks...
Molar mass of H2= g/mol
100.0g H2 • 1 mol H2/? g H2 • ? Mol NH3/ ? Mol H2 = ? Mol NH3
Molar mass of N2= ? g/mol
100.0g N2 • 1 mol N2/ ? g N2 • ? Mol NH3/ ? Mole N2 = ? Mol NH3
Molar mass of NH3 = ? g/mol
100.0g N2 • 1 mol N2/ ? g N2 • ? Mol NH3/ ? Mol N2 • ? g NH3/ 1 mole NH3 = g NH3

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
