Ethyl alcohol (CH3CH2OH) is converted to bromoethane (CH3CH2Br) by HBr according to the reaction: CH3CH2OH + HBr → CH3CH2Br + H2O If 10.23 g of bromoethane are produced when 5.00 g of ethanol is reacted with excess HBr, what is the percentage yield? ANSWER: 86.1%, just need steps thanks!!

PROBLEM Calcium chlorite and sodium hydroxide react according to the followingchemical equation: a) Balance the chemical equation.Ca(ClO2)2 + NaOH → Ca(OH)2 + NaClO2 b) Given 5.74g of calcium chlorite and 3.86g of sodium hydroxide, which of the reactants is the limiting reagent? c) What is the greatest molar amount of calcium hydroxide that can be made under these conditions? d) Using your answer from part c, calculate the mass in grams of calcium hydroxide produced.

Aspirin can be prepared from salicylic acid ( C7H6O3), which has a molar mass of 138.12 g/mol, and acetic anhydride (C,H§O3), which has a molar mass of 102.04 g/mol. The density of acetic anhydride is 1.082 g/mL. C7H6O3 + C4H6O3 → C9H804 + C2H3O2 What is the theoretical yield, in grams, of aspirin (C,H3O4), which has a molar mass of 180.15 g/mol, possible when reacting 3.01 g of salicylic acid with 3.73 mL of acetic anhydride? Type answer:

Pay attention to sig figs also. Upload your recording.  C4H8(g) +  6 O2(g)  ⟶⟶4 CO2(g)  +  4 H2O(g) Using the reaction above, show and explain on video how many liters of carbon dioxide can be created if I start with 0.2495 grams of C4H8 gas at STP?

Glucose oxidation is a chemical process that provided energy for an organism to carry out all of its regular activities.  The equation for the oxidation of glucose (C6H12O6) is: C6H12O6(aq) + 6O2(aq) →6CO2(aq) + 6H2O(ℓ) How many moles of O2 are needed to completely react with 15.39 g of C6H12O6 ? Answer to 2 decimal places.

For the reaction: 4N2H4(g)+2N2O4(g)→6N2(g)+8H2O(l) the theoretical yield of H2O is15.7g. Suppose that the actual yield of H2O is 11.0g, what is the percent yield?

Sulfuric acid, H2SO4, is an important industrial chemical, typically synthesized in a multi-step process. What is the percent yield if a batch of H,SO̟ has a theoretical yield of 3.9 kg, and 2.8 kg are obtained at the end of the process? Type answer:
