2.9g of beta-napthol and 1.65g of KOH were dissolved in 20ml of methanol with 1.8 ml of etl in a 50ml in round bottom flask and reacted to form 0.47 g of nerolin.  What is the theoretical, actual and percent yield

A process by which zirconium metal can be produced from the mineral zirconium (IV) orthosilicate, ZrSiO4, starts by reacting it with chlorine gas to form zirconium (IV) 4» chloride. ZrSiO4 + 2 Cl2 → ZrCl4 + SiO2 + O2 If 862 g ZrSiO4 and 950. g of Cl, are available, what is the limiting reactant (blank 1, no subscripts needed)? What is the mass of ZrCl4 (blank 2, no decimal places, rounded to the nearest 100)?

30) What is the percent yield for the reaction below? Only 28.16 g of CO2 are observed to have formed even though stoichiometry would predict the production of 225.3 g of CO2 since 4.000 X100 moles of C3H18 and 8.000 moles of O2 were used. 2 C8H18+ 25 O2 → 16 CO2 + 18 H2O A) 12.50% B) 25.00% C) 50.00% 20.00%

Aqueous hydrobromic acid (HBr) reacts with solid sodium hydroxide (NaOH) to produce aqueous sodium bromide (NaBr) and liquid water (H2O). If 0.976g of sodium bromide is produced from the reaction of1.6g of hydrobromic acid and 1.4g of sodium hydroxide, calculate the percent yield of sodium bromide.

Aqueous hydrochloric acid  HCl  reacts with solid sodium hydroxide  NaOH  to produce aqueous sodium chloride  NaCl  and liquid water  H2O . If  0.226g  of sodium chloride is produced from the reaction of  0.73g  of hydrochloric acid and  0.43g  of sodium hydroxide, calculate the percent yield of sodium chloride.

If you are given 2.5g of C2H4 and 2.75g of O2 to conduct the combustion reaction below: C2H4 + 3O2 = 2CO2 + 2H2O What is the chemical formula for the limiting reagent?  What is the theoretical mass of CO2 formed in this reaction in grams?  When this reaction is run in the laboratory, only 1 g of CO2 are collected.  What is the % yield of this process?  Theoretically, how many grams of the reagent that is in excess is left after the reaction?

How many moles of NO₂ would be required to produce 2.23 moles of HNO₃ in the presence of excess water in the following chemical reaction? 3 NO₂(g) + H₂O (l) → 2 HNO₃(g) + NO(g). Round to right amount of sig figs.

Urea (NH2)2CO) is prepared by reacting ammonia with carbon dioxide according to the equation.  2NH3(g) + CO2(g)  ➡ (NH2)CO(s) + H2O(l) In one process, 632.2g of NH3 reacted with 1142g of CO2  Calculate the percentage of nitrogen in urea Will urea be soluble in water? Explain Suggest a possible use for urea

Aluminum reacts with bromine, producing aluminum bromide:                 2A1(s) + 3Br2(1) → 2A1Br3(s) In a certain experiment.20.0mL of bromine(density3.10g/mL) was reacted with excess aluminum to yield 50.3g of aluminum bromide. What is the percent yield for this experiment?
