- A Commercial sodium "hydrosulfite" is 90.1% Na2S2O4. The sequence of reactions used to prepare the compound is Zn(s) + 2 SO2(g) ZnS2O4(s) ZnS2O4(s) + Na2CO3(aq) ZnCO3(s) + Na2S2O4(aq) (a) What mass of pure Na2S2O4 can be prepared from 125 kg of Zn, 500. g of SO2, and an excess of Na2CO3? (b) What mass of the commercial product would contain the Na2S2O4, produced using the amounts of reactants in part (a)?arrow_forwardA sample of an iron alloy contains 92.1 g Fe. 2.59 g C. and Cr. Calculate the percent by mass of each component present in the alloy sample.arrow_forwardWhat number of atoms of nitrogen are present in 1.00 g of each of the compounds in Exercise 51?arrow_forward
- What does it mean to say an equation is balanced? Why is it important for an equation to be balanced?arrow_forwardA 1.500-g sample of a mixture containing only Cu2O and CuO was treated with hydrogen to produce 1.252 g of pure cupper metal. Calculate the mass percent of Cu2O in the original mixture.arrow_forwardcertain transition metal ion (Mn+) forms a compound with oxygen (MxOy) . The molar mass of the compound is 250.2 g/mol.

- A substance X2Z has the composition (by mass) of 40.0% X and 60.0% Z. What is the composition (by mass) of the compound XZ2?arrow_forward3.87 Nitric acid (HNO3) can be produced by the reaction of ni- trogen dioxide (NO2) and water. Nitric oxide (NO) is also formed as a product. Write a balanced chemical equation for this reaction.arrow_forwardChalky, white crystals in mineral collections are often labeled borax, which has the molecular formula Na2B4O7 10H2O, when actually they are partially dehydrated samples with the molecular formula Na2B4O7 5H2O, which is more stable under the storage conditions. Real crystals of borax are colorless and transparent. (a) Calculate the percent mass that the mineral has lost when it partially dehydrates. (b) Is the percent boron by mass the same in both compounds?arrow_forward
- The compound As2I4 is synthesized by reaction of arsenic metal with arsenic triiodide. If a solid cubic block of arsenic (d = 5.72 g/cm3) that is 3.00 cm on edge is allowed to react with 1.01 1024 molecules of arsenic triiodide, what mass of As2I4 can be prepared? If the percent yield of As2I4 was 75.6%, what mass of As2I4 was actually isolated?arrow_forwardIf you had a mole of U.S. dollar bills and equally distributed the money to all of the people of the world, how rich would every person be?
