The following data were obtained from experiments to find the molecular formula of procaine, a local anesthetic, which contains only carbon, hydrogen, nitrogen, and oxygen. complete combustion of a 3.54g sample of procaine with excess o2 formed 8.58 g of co2 and 2.70 g h2o. another sample of mass 2.35 g was found to contain 0.279 g of n. the molar mass of procaine was found to be 236.find the molar formula of procaine

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant

What volume would 2.25 moles of ne has occupy at stp?

Scientists are often interested in knowing the molar heat of combustion – the heat released during the combustion of one mole of a substance. use the periodic table to find molar masses. how many moles of ethanol are present in the sample?
