Explain wat is meant by saying that the sharing of electrons b/w atoms falls on a continuum...?

Question

Explain wat is meant by saying that the sharing of electrons b/w atoms falls on a continum frm covalent -> ionic bonds.

How many of these elements are found nxt to each other (sideby side) on the periodic table?

a) 1 group of 2

b) 2 groups of 2

c) 1 group of 2 and 1 group of 3

d) 1 group of 3

e) all

H2CO3 <----> HCO3 1- + H+

in which direction will this rxn proceed

a) when ph of solution begins to fall?

b) when ph rises above normal lvl?

Answer 1

H2CO3 &lt;----&gt; HCO3 1- + H+

in which direction will this rxn proceed

a) when ph of solution begins to fall? as th e pH falls , it gets more acidic...

more H+ shifts the reaction away from the H+ to the left:

H2CO3 &lt;= &lt;= &lt;=  HCO3 1- + H+

b) when ph rises above normal lvl?

when the pH rises. the solution is less acidic,

less H+ ion causes a shift to the right to restore the lost H+ :

H2CO3 =&gt; =&gt; =&gt;  HCO3 1- + H+
