Starting with 2.2 mol NO, calculate how many moles and how many grams of O2 are required for complete reaction. Calculate what mass of NO2, in grams, is produced.arrow_forward
- The catalytic converter that is standard equipment on American automobiles converts carbon monoxide (CO)to carbon dioxide (CO2) by the reaction 2CO + O2 2CO2 What mass of O2, in grams, is needed to react completely with 25.0 g of CO?arrow_forwardBoron forms an extensive series of compounds with hydrogen, all with the general formula BxHy. To analyze one of these compounds, you burn it in air and isolate the boron in the form of B2O3 and the hydrogen in the form of water. You find that 0.1482 g BxHy gives 0.4221 g B2O3 when burned in excess O2. Determine the empirical I formula of BxHy.arrow_forwardYou take 1.00 g of an aspirin tablet (a compound consisting solely of carbon, hydrogen, and oxygen), burn it in air, and collect 2.20 g CO2 and 0.400 g H2O. You know that the molar mass of aspirin is between 170 and 190 g/mol. Reacting 1 mole of salicylic acid with I mole of acetic anhydride (C4H6O3) gives you 1 mole of aspirin and 1 mole of acetic acid (C2H4O2). Use this information to determine the molecular formula of salicylic acid.arrow_forward
