The first step in the Ostwald process for producing nitric acid is as follows:4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g).If the reaction of 15.0 g of ammonia with 15.0 g of oxygen gas yields 8.70 g of nitric oxide, what is the percent yield of this reaction?

Aluminum reacts with bromine to form aluminum bromide (used as an acid catalyst in organic synthesis).Al(s) + Br2(l) → Al2Br6(s) How many moles of Al are needed to form 2.43 mol of Al2Br6?

Methanol (CH3OH) is converted to bromomethane (CH3Br) as follows:CH3OH + HBr → CH3Br + H2OIf 12.23 g of bromomethane are produced when 5.00 g of methanol is reacted with excess HBr, what is the percentage yield?

What mass of sodium fluoride (used in water fluoridation and the manufacture of insecticides) is required to form 485 g of sulfur tetrafluoride?3SCl2(l) + 4NaF(s) → SF4(g) + S2Cl2(l) + 4NaCl(s)

One way of obtaining pure sodium carbonate is through the decomposition of the mineral trona, Na3(CO3)(HCO3)·2H2O.2Na3(CO3)(HCO3)·2H2O(s) → 3Na2CO3(s) + CO2(g) + 5H2O(g)When 1.00 metric ton (1.00 × 103 kg) of trona is decomposed, 0.650 metric ton of Na2CO3 is recovered. What is the percent yield of this reaction?
