An engineer was trying to minimize greenhouse gases from car exhaust and was studying the gases that come from the trail pipe of a car at 800K. He discovered that 2 moles of carbon dioxide can react to form carbon monoxide gas and oxygen gas. He collects 5.00 L of an equilibrium mixture of the exhaust and determines that he has 5.23 M CO2, 0.125 M CO, and 0.256 MO2. In an attempt to minimize the polluting carbon monoxide he adds to the mixture 0.250 moles of oxygen gas. What will the new concentration of carbon monoxide be?
A. Liquids have very strong attractive forces holding them together B. Liquids have moderately strong attractive forces holding them together C. Liquids have very weak attractive forces holding them together.
How many silver atoms can be produced if 0.00350g of Cu are reacted with excess AgNO3, according to the equation :Cu + 2AgNO3 yields 2Ag + Cu(NO3)2
