I need help ASAP please<br> Calculating pH<br> See chart below
laila [671]

Answer:

12, basic, 9, basic

Explanation:

pH = -log[H+]

Using the data in the table, you can calculate the pH:

-log[1e-12] = 12

-log[1e-9] = 9

To find out whether it is acidic, basic, or neutral, use a pH scale. Anything less than 7 is acidic, anything over is basic. Knowing this, both will be basic.

What is the equilibrium associated with ka3 for h3po4?
Vlad [161]
Phosphoric acid has 3 pKa values (pKa1=2.1,  pKa2=6.9, pKa3= 12.4) and after 3 ionization it gives 3 types of ions at different pKa values: 

H₃PO₄(aq) + H₂O(l) ⇌ H₃O⁺(aq) + H₂PO₄⁻ (aq)         pKₐ₁ 
<span>

</span>H₂PO₄⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + HPO₄²⁻ (aq)       pKₐ₂


HPO₄²⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + PO₄³⁻ (aq)          pKₐ₃ 

The last equilibrium is associated with the highest pKa value (12.4) of phosphoric acid. There the last OH group will lose its hydrogen and hydrogen phosphate ion (HPO₄²⁻) turns into phosphate ion (PO₄³⁻).

1. What is an isomer? How many possible isomers of hexane are there? What are the structural differences between these isomers?
UNO [17]
When two compounds have same molecular formula but different structural formula, they are said to be isomers of each other and this phenomenon is called as isomerism. 

Hexane has six isomers.

The isomers of hexane have a difference in their structure due to parent chain length (chain isomerism). They are also differentiated on the basis of straight chain as in n-hexane and branched chain as in remaining five. Structures along with names are shown below.
