For a given reaction, which statement is true? a. The equilibrium constant is always the
same number, but the concentration of
reactants and products can vary at
equilibrium.
b. The equilibrium constant is always the
same number as long as the
temperature is held constant.
c. The equilibrium constant is always the
same number as long as the pressure is
held constant
d. The equilibrium constant is always the
same number as long as the
concentration of CO2​ is held constant

How will the emission of an alpha particle affect the atomic number of an atom

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.
