Hi I need help with this math problem: The plane that contains the points (8,3,1), (2,6,3), and (4,6,2) has an equation of the form ax + by + cz = d. Find coefficients for this equation, trying two different approaches to the problem. One method uses vectors, another does not...

**Limiting Reagents**

in the synthesis of FeC2O4 (dot) 2H2O, which reagent would be the limiting reagent? FeSO4(NH4)2SO4 (dot) 6H2O - 2.68g. H2C2O4 (dot) 2H2O - 1.99g. I just want to know how the H2Os would effect finding the limiting reagent. As in do they change the ratio? The molecular mass? ...
