Carbon tetrafluoride, CF, contains four identical C-F bonds. Fluorine is more electronegative than carbon. How will this impact each of the bonds between carbon and
fluorine?
a. The electrons in each C-F bond will be more attracted to the carbon atom.
b. The electrons in each C-F bond will be attracted equally to both atoms.
C. The electrons in each C-F bond will be more attracted to the fluorine atom.
d. The electrons in each C-F bond will separate easily.

What problem would a person have if the nucleic acid in one of his or her cells were damaged?

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.

Precision can be defined as the o exact center of a data set. o reproducibility of a measured value. o correlation between two variables that are measured in a data set agreement between a measured value and an accepted value.
