Write a ground state electron configuration for these ions. remember that ions have a
change in the total number of electrons (positive have lost electrons and negative have
gained). example: n3.is 1s 2s 2p. it has three extra electrons
11. 02-
13. b3+
15. k
12. fe2+
14. ni2+
16. co3+
17. if each orbital can hold a maximum of two electrons, how many electrons can each of the
following hold?
a. 2s
c. 4f
e. 4d
b. 5p
d. 3d
18) isoelectronic species have similar electron configurations. which of these are isoelectronic?
a) li*, h, he
b) ca2+, ne, s?

answer; /// i do believe that the correct answer is (a) boiling

no but i do not usually comment or use my voice that much when it comes to social media

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
