From the balanced equation: 1 mol CO reacts with 2 mol H2 to produce 1 mol CH3OH Molar mass CO = 12+16 = 28 g/mol Mol CO in 356 g = 356 g /28 g/mol... Which reagent is the limiting reagent? In an experiment, 1.25 g of NH3 are allowed to react with 3.50 g of O2 02 NH3 NO H2O there is no limiting reagent in this reaction ANSWERS: 1. a) yes b) yes c) .59g K2O 2.a) 16g NaOH b) Na2O 3. a) 3.5 mol CH4 b) 6.7g CH4 4. If you do not know what products are, enter reagents only and click 'Balance'. The answers are given for your reference Take the reaction: NH3 + O2 → NO + H2O. 3) Perform the stoichiometry using the limiting reagent as the “given” quantity Q - How many g NO are produced if 20 g NH3 is burned in 30 g O2? Balance the equation for this reaction: ___NH3 (l) + ___O2 (g) ( ___ NO (g) + ___H2O (g) b. In an experiment, 3.25 g of NH3 are allowed to react with 3.50 g of O2. Nitric oxide is made from the oxidation of ammonia. a. If 4.95 g of ethylene (C2H4) are combusted with 3.25 g of oxygen. a. How many grams of NO are formed? a. 2) Divide by coefficients of balanced equation: (is this balanced?) The reactant that produces a lesser amount of product is the limiting reagent. c. How much of the excess reactant remains after the reaction? b) How much NO is formed? Mass of NH3 = 3.25g Molar mass of NH3 = 14+3 = 17g/mol Moles of NH3 = mass/molar mass = 3.25g/17g/mol =0.191mol Moles of NH3 = 0.191mol Mass of O2=... Step 1: 21.6 g NH3 and excess O2 produce 1.90 mol H2O. Oxygen is the limiting reagent. 4 NH3 + 5 O2 ––––> 4 NO + 6 H2O. In an experiment, 3.25 g of NH3 are allowed to react with 3.50 g of O2. Limiting Reagent Before and After Reaction. Limiting Reagents. Extra Practice 1. C2H4+3O2--->2CO2+2H2O a. C2H4 b. O2 9. Examples: What would be the limiting reagent if 78 grams of Na2O2 were reacted with 29.4 grams of H2O? nh3 o2 no h2o. What is the limiting reagent? is the mole relationship between two specific chemicals: Example: The mole ratio between H2/H2O is: 2 mole H2 = 2 mole H2O. 6 mol H 2 O 2 mol C 2 H 6! NH3 (g) + O2(g) → NO(g) + H2O(l) If 2.00 g of ammonia is reacted with 4.50 g of oxygen. For O2: n = m/M = 40.5g/32.00gmol^-1 = 1.27mol. Convert 21.6 g NH3 to moles, then find the corresponding amount of H2O. If you do not know what products are, enter reagents only and click 'Balance'. Guided problems as well as a randomized calculation activity… Remaining excess reagent(NH3) = 3.25–1.49 = 1.76 g You can use parenthesis or brackets []. STOICHIOMETRY 2C2H6 + 7O2 4CO2 + 6H2O What volume of H2O would be produced by 1.40 mol of O2 and sufficient ethane iven: mole ratio of O2:H2O = 7:6 moles of O2 = 1.40mol 6 mol H2O = x 7 mol O2 1.40 mol O2 0.8571 = x 1.40 x = 0.8571 x 1.40 = 1.20 mol of H2O But the question asked for volume!!!
