How is vacuum filtration completing the purification of your sample? Where are the impurities at this point? For a recrystallization lab in organic chemistry
A sample of a substance (containing only C, H, and N) is burned in oxygen. 8.696 g of CO 2 , 2.225 g of H 2 O and 4.446 g of NO are the sole products of combustion. What is the empirical formula of the compou ...
What are Transition Metals and what specifically happens to transition metals that results in solutions that give off distinct colors?
A student weighed out 1.74 grams of sodium hydroxide pellets and added them to 48.0 grams of water in a calorimeter. Extrapolating back to the time of mixing yielded a temperature change at the time of mixing equal to 9. ...
