Identify the relative molar amounts of the species in 0.10 M NaBr(aq). If equal, place the species in the same box. H2O OH- H30+ Br- Na+ NaBr
In an experiment, equal volumes of 0.00200M FeCl3 and 0.00200M NaSCN were mixed together and reacted according to the equation:
If 0.80g of gas occupies 295 mL at 25 degrees celsius and 680 mm Hg of pressure, what is the molar mass of the gas?
If you add a solvent called "dioxane" to water, a homogenous mixture forms. Dioxane and water have the same boiling point (100oC). How do you explain that the mixture of the two compounds shows a boiling point that is lower than the one found for ..
