Calculate the composition, in weight percent, of an alloy that contains 105 kg of iron, 0.2 kg of carbon, and 1.0 kg of chromium.

Sodium hydrogen sulfate is used as a cleaning agent and as a flux (a substancethat promotes the fusing of metals and prevents the formation of oxides). Oneof the ways in which sodium hydrogen sulfate is manufactured is by reactingsodium dichromate, Na2Cr2O7, with sulfuric acid. This process also forms waterand chromium(VI) oxide, CrO3.a. Write a balanced equation for this reaction. (You do not need to includestates.)b. How many kilograms of sodium dichromate, Na2Cr2O7, are necessary toproduce 130.4 kg of sodium hydrogen sulfate?c. How many kilograms of chromium(VI) oxide are formed when 130.4 kg ofsodium hydrogen sulfate is made?d. What is the minimum volume of 18.0 M H2SO4 solution necessary toreact with 874.0 kg of sodium dichromate?e. What is the maximum mass of sodium hydrogen sulfate, NaHSO4, thatcan be formed from the reaction of 874.0 kg of sodium dichromate with400.0 L of 18.0 M H2SO4?
