A chemist ran the reaction and obtained 5.40 g of ethyl butyrate. What was the percent yield, The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield. How many grams would be produced from 7.45g of butanoic acid and excess ethanol?

Yeast converts glucose (C6H12O6) into ethanol (d=789g/mL) in a process called fermentation. An equation for the reaction can be written as follows: If 100.0g of glucose yields 50.0mL of ethanol, what is the percent yield for the reaction?

What are the number of moles CO2 obtained from the combustion of 1 mol of butane?

The number of moles of NaOH used is 0.5 and number of moles of methyl salicylate is 0.023 . What is the limiting reagent and please calculate the theoretical yield of the salicylic acid product in grams

Apidic acid (H2C6H8O4) is used to produce nylon. Apidic acid is made commercially by a reaction between cyclohexane (C6H12) and oxygen (O2).   What is the balanced reaction for this transformation? (Hint: Water is formed as a by-product.)    Assume that cyclohexane is the limiting reagent. You start with 25.0 g of cyclohexane. How much apidic acid could be produced? c.    In reality, you only made 33.5 g of apidic acid. What is your % yield for the reaction?

A chemist carries out this reaction using 10 moles of acetone and 16 moles of benzaldehyde and obtains 6 moles of dibenzalacetone. What is the percent yield for this reaction?

What is the total mass of products expected from the combustion of 20.3 g of ethane?

Citric acid (C6H8O7) is made by fermentation of sugars such as sucrose (C12H22O11) in air. Oxygen is consumed and water generated as a by-product.(a) Write a balanced equation for the overall reaction that occurs in the manufacture of citric acid from sucrose.(b) What mass of citric acid is made from 15.0 kg sucrose?

Aqueous hydrobromic acid HBr reacts with solid sodium hydroxide NaOH to produce aqueous sodium bromide NaBr and liquid water H2O . What is the theoretical yield of sodium bromide formed from the reaction of 5.7g of hydrobromic acid and 3.9g of sodium hydroxide?

Hydrogen cyanide gas can be made by a two step process. First, ammonia is reacted with oxygen gas to give nitrogen monoxide and water vapor. In the next step, nitrogen monoxide is reacted with methane (CH4) to give hydrogen cyanide gas. The by-products are water and hydrogen gas. Write the balanced equation for the two reactions.  When 21.6 g of ammonia and 28 g of methane are used, how many grams of hydrogen cyanide can be produced? (This is a limiting reactant problem)
