Homework Answers
To write empirical formula , firstly we will see the smallest unit and then we will devide all number of compounds by this unit as shown below:
5.a) C8H18
Here 8 is the smallest unit ,divide it to both the compound numbers.
Empirical formula : C1H(2.25)
5.b) Hg2Cl2
Here 2 is smallest unit .
Empirical formula : Hg1Cl1
5.c) C3H8O3
Here 3 is smallest unit.
Empirical formula : C1H(2.7)O1
6.) Electronic configuration of an atom of gold :
Au: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 4p14 5d10 6s1
7) Electronic configuration of selenide ion:
Selenium : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4
Selenide ion = Se 2- : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6
