calculate the mass (g) of the excess reactant after thereaction is complete e. calculate the theoretical yeild (g) of 2,2dibromopropane
what will the final mixture contain if 14.0 g of N2 and 35.5 g of Cl2 react to completion and the balanced equation is: N2+3Cl2--->2NCl3
What is a meniscus? Why do some liquids develop a meniscus? How do we read the liquid level in a volumetric measuring device
This indicates that the unknown material is a pure compound? Not be a pure compound, suggest an alternate procedure to verify the purity of the sample
