8. Given the following six figures (at room temperature). Match them to the following compounds/molecules: HI, P₂H4, Fe₂O3, Na2S (cation dark sphere, anion open sphere), CaF2(cation dark sphere, anion open sphere), KF.

Another important piece of information we can get from the chemical formula is if the compound is ionic or covalent. Ionic compounds, generally, have elements that gain or lose electrons to hold opposite charges to create an attraction, while covalent have only nonmetals that share their electrons. This is a pretty important distinction and for the most part, ionic compounds are going to be made from metals and a nonmetal or a metal and a polyatomic ion - seeing a metal in the formula is a pretty good indicator if the substance is ionic or not. Given the compounds below, which one is most likely to be ionic?   Options:   Cl2   CO2   Na3PO4   C6H12O6

We've spent quite a bit of time thinking about the interactions between atoms or molecules, one of which is called London dispersion forces. The stable interactions between two atoms we briefly discussed, in this case a covalent bond. We will explore more about this type of interaction in a minute. But let's say for now that it takes 348 kJ/mol to break 1 mole of C-C bonds (that is, 6.022 * 1023 C-C bonds). What would be the minimum frequency of a photon that could break a single (1) C-C bond? What region of the EM spectrum would this light be in? Enter your answer here

As seen in the table, compounds containing an integer ratio of elements depend on how many cations combine with how many anions to form a stable compound. For example, in table 1, to form a NaCl compound, first Na ionizes from the Na+ cation which is having +1 positive charge, which will lose 1 electron, it is having +1 charge, this electron then goes to Cl and it will change to Cl- anion by gaining the electron, so here 1:1 ratio charge which means 1 Na+ combines with 1 Cl-1 to form NaCl. So here integer ratio is 1:1 for this sodium chloride compound. As listed in table 2, Mg(OH)2, the integer ratio is 1:2 which means, Mg is a neutral atom that loses 2 electrons and forms an Mg+2 cation, which combines with OH which gains 1 electron to form OH- anion, So here Mg2+ can combine with 2 OH- anion,  so they both combine to form Mg(OH)2 which has integer ratio as 1:2 . Thus, atom forms as ions by losing or gaining electrons and combines together in whole number ratio to form stable…
