Document Summary

The volume of the mixture is 19. 25 ml. A. k2cr2o4, b. h3p3o3, c. n2o4, c2h6, d. Kmno4: consider a solution of ethyl alcohol and water. A. heterogeneous mixture, b. homogeneous compound, c. pure element, d. homogenous mixture, e. none of the above: balance the following equation using the smallest whole numbers as stoichiometric coefficients. Calculate the sum of the coefficients of the reactants and the products. C2h2 (g) + o2 (g) co2 (g) + h2o (l: one formulation for rocket fuel uses hydrazine and dinitrogen tetroxide. They react according to the following balanced equation: Mm n2h4 +32. 05 g/mol, mm n2o4 = 92. 02 g/mol. 2n2h4 (l) + n2o4 (g) 3n2 (g) + 4h2o (l) How many grams of n2 can be produced from a mixture of 53. 2 g of n2h4 and 65. 3 g of. N2o4 if the percent yield for the reaction is 67%: a mixture of argon and helium contains 3 moles of helium and 2 moles of argon.
