The pressure on a fixed ma decrease lease, orremalon a fixed mass of a gas is tripled at constant temperature. will the volume increase remain the same? 5.35 at what pressure does the gas occupy a volume of 5 0: 37 calculate the boyle's law constant at a volume of 2 l.? charles's law - 5.41, 5.43, 5.45, 5.49, 5.51 5.41 state charles's law in words. 5.43 explain why the kelvin scale is used for gas law calculations 5.45 the temperature of a gas is raised from 25°c to 50°c. will the volume double if mass and pressure do not change? why or why not? 5,49 a balloon containing a sample of helium gas is warmed in an oven. if the balloon measures 1.25 l at room temperature (20°c), what is its volume at 80'c?

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
