Consider two reactants (A and B) that when mixed form a precipitate C, which can be filtered, dried, and then weighed. Carlos attempts to find the stoichiometric ratios in which A and B mix, by mixing different volumes of the same concentration of solutions of A and B (0.50 M). He records the following data:
Run Vol A (mL) Vol B (mL) Mass C (g)
1 10.0 10.0 1.17
2 20.0 10.0 2.33
3 30.0 10.0 3.50
4 40.0 10.0 3.50
Assuming that the products of the reaction are C and D, and that the stoichiometric coefficients for C and D are 1 and 2 respectively, the balanced chemical reaction will be
( ) A + ( ) B â 1 C + 2 D

Jason combines the two intermediate steps shown. na(g)+o2(g) -> 2no(g) 2no(g)+o2(g) 2no2(g) which best describes what jason should do with the oxygen molecules? place two of them as products. place two of them as reactants. cancel them out because there is one in each equation. double them because there is one in each equation.
