Lewis Structures
Here's one of my problems:
1. Draw the Lewis structures for the following molecules or polyatomic ions:
a.) NH3
b.) SiO2
c.) OH-1
how do you do this?
-------------------------------
problem 2:
Find the Hybridizations, shapes, and expected bond angles of the central atoms in the following molecules:
a.) SiO2
b.) CH2O
c.) OF2
how do you do these problems?
---------------------------------------
Problem 3:
how do you find Molar Mass?
--------------------
Problem 4:
Find the molar mass of the following compounds:
a.) Na2SO4
b.) nitrogen trichloride
c.) fluorine
i am new at chemistry so this is all a blur, i need step by step answers!
