Why are most anions basic in H2O? Give formulas of four anions that are not basic.
AVprozaik [17]

Answer:

The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.

How many bonds can sodium form
Tresset [83]

it exists as atom or ion but not as sodium molecule. So there is no any sodium sodium bonding between two sodium atoms. Sodium combines with other element or group to form compounds of sodium like sodium chloride ,sodium carbonate ,sodium sulphate etc. Sodium has symbol Na and its atomic no. is 11 .

based on what you wrote in the table in part a, what effect do lone pairs have on the bond angle? why do you think this happens?
umka21 [38]

Because they are more in close proximity to the core atom's nucleus than lone pairs are, lone pairs reject other lone pairs more strongly than bonding pairs do effect the bond angle.

When a single pair of electrons at the central atom begins to resist the bound pair of electrons, the bond angle decreases and the bonds are slightly shifted inward. It moves existing atoms closer together and modifies their geometry. It's equivalent to include an atom. When there is an increase in back bonding, the bond angle rises. Because the lone pair electrons of the two atoms reject one another, adjacent atoms in a molecule that have lone pair electrons will not be kept together in their bond as securely.

Please help with this chemistry question!
marusya05 [52]

Hey there!

Compounds with ionic bonds have higher melting points because of the forces needed to break through the strong forces of attraction holding it together.

Compounds with covalent bonds have lower melting points because less energy is needed to break the weaker forces of attraction.  

So, your answer is C. Compound 1 is ionic, and compound 2 is molecular.

Hope this helps!

The average atomic mass of copper is 63.55 amu. If the only two isotopes of copper have masses of 62.94 amu and 64.93 amu, what
IgorLugansk [536]

Explanation:

Let relative ratio of one isotope (62.94 u) be X

Then, relative ratio of other isotope (64.93) will be (1 - X)

Now,

(62.94)x + (64.93)(1 - x) = 63.55

1.99x = 1.38

X = 0.69

<u>Relative Abundance</u> :

(62.94 u) isotope = 69 %

(64.93 u) isotope = 31 %
