Lithium has an oxidation of +1, and Fluorine an oxidation of -1, therefore if they reacted they would only need one atom of each to become stable. Question 4 options:
True
False

If Magnesium and chlorine reacted, it would require two Magnesium and one chlorine to become stable.

Question 5 options:
True
False

If Calcium reacts with Nitrogen, the proper ratio of atoms to become stable would be 3 calcium's and two Nitrogen's.

Question 6 options:
True
False

When water forms, two hydrogen atoms covalently bond with one oxygen atom, and Hydrogen through this electron sharing takes on the electron configuration of helium, and oxygen takes on the electron configuration of Neon.

Question 7 options:
True
False

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.

Compare and contrast physical changes with chemical changes.

Imagine that twenty i.u.’s of enzyme z were catalyzing the above reaction for one minute, under vmaxconditions, in a 3.00 ml assay volume. the assay is buffered with 20 mm phosphate buffer, ph 7.60. what will the ph be at the end of that one minute?
