Answer:
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.

Answer:
~.1058 Moles
Explanation:
The formula for this question is the following.
1 mole of a compound/molar mass of the compound.
First we need to find the molar mass of H2O, which is the atomic mass on the periodic table. Hydrogen is 1.01, Oxygen is 16.00. Add those together to get the molar mass of the compound and you'll get an equation that looks like this.
1 mole of H2O/ 17.01 g/mol H2O
We now know that in 1 mole of H20 there is 17.01 g.
Take 1.8g and divide it by 17.01, you get your answer.
Here are the solutions:
For NaCl, there would be one electron transferred from the sodium atom, now producing a cation to the chlorine atom resulting in a chlorine anion. Forming ionic bond.
For CaS, there would be 2 electrons transferred from an atom of Ca to S, this can be obtained by simply looking at the ionic charges and or combining capacities of Ca.
For BaO, likewise, 2 electrons that are valence electrons are transferred from Ba to Oxygen.
In the ionic compound of KBr, the atom of K, potassium donated its one valence electron to Br, in need of it to achieve a stable octet, and produce the chemical bond.
Finally, LiF, a single valence electron is transferred from a metal atom of Li to F, for both of the atoms that would form the ionic bond to achieve a stable octet, and or full electron shell.
a...if you had the fully extended periodic table, these elements would be between La and Hf in period 6 and Ac and Rf in period 7
