Which of the postulates of Dalton’s atomic theory explains why we can calculate a theoretical yield for a chemical reaction?
A newspaper article about the danger of global warmingfrom the accumulation of greenhouse gases such as carbondioxide states that “reducing driving your car by 20 milesa week would prevent release of over 1000 pounds of CO2 per year into the atmosphere.” Is this a reasonable statement?Assume that gasoline is octane (molecularFormula C8H18 ) and that it is burned completely to CO2 and H2O in the engine of your car. Facts (or reasonable guesses)about your car’s gas mileage, the density of octane, andother factors will also be needed.
When elemental carbon is burned in the open atmosphere, with plenty of oxygen gas present, the product is carbon dioxide. :math>C(s)+O2(g)CO2(g) wever, when the amount of oxygen present during the burning of the carbon is restricted, carbon monoxide is more likely to result. :math>2C(s)+O2(g)CO(g) at mass of each product is expected when a 5.00-g sample of pure carbon is burned under each of these conditions?
Hydrogen peroxide is used as a cleaning agent in the treatment of cuts and abrasions for several reasons. It is an oxidizing agent that can directly kill many microorganisms: It decomposes upon contact with blood, releasing elemental oxygen gas (which inhibits the growth of anaerobic microorganisms); and it foams upon contact with blood, which provides a cleansing action. In the laboratory, small quantities of hydrogen peroxide can be prepared by the action of an acid on an alkaline earth metal peroxide, such as barium peroxide. BaO2(s)+2HCl(aq)H2O2(aq)+BaCl2(aq) What amount of hydrogen peroxide should result when 1.50 g of barium peroxide is treated with 25.0 mL of hydrochloric acid solution containing 0.0272 g of HCI per mL?
