Re: Oxoacids

Yes, oxoacids are acids which contain one more oxygen atoms. They are treated as a different category I believe because in acids with oxygen, their strength is affected by the number of oxygen atoms in the acid since more oxygen atoms will cause more electrons to be pulled away, making the acid stro...

Re: Temperature in PV=nRT

Temperature has to be in Kelvin always. Unlike P or V in the PV=nRT equation, where P can be in atm/Pa/etc or V can be L/m^3/etc or they can both be combined into eV/J/cal, T always has to remain in K (similar to n, which always has to remain in mol).

Re: Value of R

Yes, R in the equation PV=nRT is a constant so it is always equal to the same value. However, you have to match the value of R in terms of the units of the other values in the equation (P, V, n, and T). The units of R when it is equal to 0.082 is L/atm/K^-1/mol^-1, so in order to use .082 for R, V m...

Re: Monatomic Anions and cations

When we think of ions usually we think of monoatomic ions where an atom of one element transfers or loses an electron to an atom of another element, creating two charged particles. However, there are also compounds that are covalently/ionically bonded that are composed of multiple atoms yet have a s...

Re: Polar covalent bonds

In a covalent bond, the two atoms share the electrons. However, if one of the atoms has a higher EN/Electron Affinity than the other, then that means that particular atom will have a stronger pull on the electron(s) and therefore the bond created will not be equal- the electrons will be closer to th...

Re: Which is more Ionic

If you look at the actual EN differences between the two compounds LiH and HCl, then you would be able to see Li and H have an actual greater difference than between H and Cl. Also, Li and H would form an actual ionic bond, since Li is a metal and H is a nonmetal, whereas H and Cl are both nonmetals...

Re: Metals

Metals in general have low Electronegativities and low Electron affinities, and this is because their valence shells aren't as complete as compared to nonmetals, so for them to achieve stability it is easier to lose the little amounts of valence electrons they have than to try and gain a lot of vale...

Re: cation vs anion

Every ionic bond will result in the formation of an anion and a cation. The anion is the atom which receives the electron (usually the nonmetal with a large EN) and the cation is the atom which donates the electron (usually the metal with a low EN). Because of this, we can say that as EN increases g...

Re: Ionic vs Covalent vs Metallic Bonds

Generally, a covalent bond is between a nonmetal and a nonmetal (which is why they have to share electrons since both usually have high electronegativities and are unwilling to fully give up an electron), an ionic bond is between a metal and a nonmetal (the large difference in electronegativities al...
