4 Al (S) + 302(g) 2AI2O3(s) When 47.90 g of Al and 80.13 g of O, were reacted, 14.22 grams of aluminum oxide were obtained. What is the percent yield? (Hint: You need to determine which one is the limiting reactant and then the theoretical yield). Your Answer: Answer units

When propane (C3Hg) reacts with oxygen, carbon dioxide and water are produced. The balanced equation for this reaction is C3 Hs (g) + 502 (g) → 3CO2(g) + 4H2O(g) If 10 moles of oxygen react, The reaction consumes moles of propane (C3H8). The reaction produces moles of carbon dioxide and moles of water.

using the equation: 2Al(s)+3Cl2(g)=Al2Cl6(s) , calculate the mass of Al required to produce 34.2g of Al2Cl6.

Liquid nitroglycerine (CaHsNaO₂) is a powerful explosive. When it detonates, it produces a gaseous mixture of nitrogen, water, carbon dioxide and oxygen. If 5.55 g of nitroglycerine explodes and 2.98 g of CO₂ is collected, what is the percentage yield of carbon dioxide?

consider the following balanced equation 15O2(g)+2C6H5COOH(aq)  ___ 14CO2(g)+6H2O(I) if 11.6 moles of O2(g) and 2.34 moles of C6H5COOH(aq) are allowed to react, and the percent yield is 76.7% how many moles of H2O(I) will actually be produced?

A sample of 4.00g of methane (CH4) is mixed with 15.0g of chlorine (Cl2). Determine which is the limiting reactant according to the following equation: CH4(g) + 4Cl2(g)> CCl4(e) + 4HCl(g)

Ammonia is produced by the balanced chemical reaction: 3H2lg) + N2g) → 2NH3(g) How many grams of ammonia can be produced from 22.7g of hydrogen with excess nitrogen present? (Hint: This is a limiting reagent question. Do not forget your significant digits and your units.) How many grams of ammonia can be formed from 36.3g of nitrogen with excess hydrogen present? (Hint: This is a limiting reagent question. Do not forget your significant digits and your units.) This is a limiting reactant problem: How many grams of ammonia can be produced from 22.7 g of hydrogen and 36.3 g of nitrogen? (Hint: This is a limiting reagent question. Do not forget your significant digits and your units. Also note that this question should be easy of you have answered Part A and Part B successfully.)

[References] Ammonia gas can be prepared by the reaction of a metal oxide such as calcium oxide with ammonium chloride. CaO(s) + 2 NH, Cl(s) → 2 NH3 (g) + H. O(g) + CaCl, (s) If 102 g of CaO and 241g of NH, Cl are mixed, what is the limiting reactant, and what mass of NH3 can be produced? The limiting reactant is CaO Mass of NH3 = 6. Drag and drop your selection from the following list to complete the answer: NH3 NH, C1 CaCl, 23

Use the balanced equation, 4K + O2-->2K2O , to answer the following question. How many grams of  O2 are needed to react completely with  16.6 g of K ? Be sure your answer has the correct number of significant figures.

In a certain chemical reaction Compound A combines with Compound B to produce Compound C (and no other products). Measurements were taken of the amounts of A and B present before and after a reaction that produced some C: Compound initial amount final amount A 9.5 g 0 g 1.5 g 0.8 g Calculate the theoretical yield of C. Round your answer to the nearest 0.1 g. Suppose thẻ percent yield of C in this reaction was 55.%. Calculate the actual amount of C that was isolated at the end of the reaction. Round your answer to the nearest 0.1 g. Explañation Check O 2020 McGraw-Hill Education. All Rights Reserved. Terms of Use | Privacy Ace olo
