If 139.05 g of iron (iii) oxide are added to 268.10 g of chlorine gas, calculate...
9) Iron(III) chloride can decompose forming iron(II) chloride and chlorine gas. Write and balance the equation for the decomposition reaction. How many mL of chlorine gas are formed if 1.00 g of iron(III) chloride decomposes at 45oC and 1.0 atm?
Calculate w (in kJ) when 445 g iron (III) oxide (MM = 159.7 g/mol) reacts with excess carbon to produce carbon dioxide gas at 458 K: 2Fe2O3(s) + 3C(s) + 4Fe(s) + 3CO2(g) Answer: 511.64 x
Write a balanced chemical equation describing the oxidation of chlorine gas by the copper (III) ion to form the chlorate ion and copper (II) in an acidic aqueous solution. Use the smallest whole number coefficients possible. I have tried the following answers and I have no idea what to do to make it correct: Thank you so much for your help! Here is the hint I was given: One way to determine the balanced equation for a redox reaction is...
Chlorine gas can be prepared in the laboratory by the reaction of hydrochloric acid with manganese(IV) oxide. 4 HCI(aq) + MnO2(s) MnClj(aq) + 2H20) +C2(g) A sample of 38.7 g MnO2 is added to a solution containing 41.3 g HC. What is the limiting reactant? O HCI O Mno, What is the theoretical yield of Cl2? theoretical yield: g Cl If the yield of the reaction is 78.9%, what is the actual yield of chlorine? actual yield: gC2 Chlorine gas...
