Part 2 (30 points) The Chemistry teachers at Durango High School discovered two new elements Below are the
boxes that will be added to the periodic table based on their discoveries
120
Du
Durandium
317
148
BZ
Blazerium
379
1. How many protons are in durandium?
2. How many neutrons are in durandium?
3. How many electrons are in a neutral durandium?
4. How many protons are in blazerium?
5. How many neutrons in blazerium?
6. How many electrons are in a neutral blazerium?

Durandium is an alkali earth metal and blazerium is a halogen.
7. What type of bonding would these elements have I f they are bonded together?
8. How many valence electrons are in durandium durandium?
9. How many valence electrons are in blazerium?

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.
