In what respect does an atom of magnesium differ from a magnesium ion (mg^{2+})?
(a)the ion has a more stable electronic arrangement than the atom.
(b)the positive charge on the nucleus of the ion is two units greater than the nuclear charge on the atom.
(c)the ion has two more protons than the atom.
(d)the ion will react more readily with free cl₂.
(e)the ion has two more planetary electrons than the atom.
can anyone explain this one?

What must happen before a body cell can begin mitotic cell division

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.
