Question

1 Review Constants I Periodic Table Part B A chemical reaction in which reactants A and B form the product C is studied in the laboratory. The researcher carries out the reaction with differing relative amounts of reactants and measures the amount of product produced. Examine the given tabulated data from the experiment and answer the questions. The molar mass of A is 50.0 g/mol, and the molar mass of B is 75.0 g/mol. What are the lowest whole-number coefficients of A and B in the balanced chemical equation? Match the numbers in the left column to the appropriate blanks in the sentences on the right.

Answer 1

Molar man of A = 50 g/mol. a u " B - 75g/mol. from expl Man of zo.Jl. n B = 7.54 mole of A 2 0 .05. R 0.00 Lowest value of mole of A in whole coltfriental . from enpa Mar of Az i u mole of A z S.03 7:51 0.1006 Lowerf value of mote of A n whole coffinners Sinra according to the op Home, I in the lowent, Hence The coefficient in the balanced chemical canation for B is 1 The coefficient in the balanced chemical caration

The answer is 1 and 1 . Only experiment value of 1 and 2 are taken as because the question has the answer of lowest value 1 .
