Find the concentration of H+ ions at a pH = 11 and
Black_prince [1.1K]

Explanation:

the pH of the solution defined as negatuve logarithm of H^+ ion concentration.

pH=-\log[H^+]

1. Hydrogen ion concentration when pH of the solution is 11.

11=-\log[H^+]

[H^+]=1\times 10^{-11} mol/L..(1)

At pH = 11, the concentration of H^+ ions is 1\times 10^{-11} mol/L.

2. Hydrogen ion concentration when the pH of the solution is 6.

6=-\log[H^+]'

[H^+]'=1\times 10^{-6} mol/L..(2)

At pH = 6, the concentration of H^+ ions is 1\times 10^{-6} mol/L.

3. On dividing (1) by (2).

\frac{[H^+]}{[H^+]'}=\frac{1\times 10^{-11} mol/L}{1\times 10^{-6} mol/L}=1\times 10^{-5}

The ratio of hydrogen ions in solution of pH equal to 11 to the solution of pH equal to 6 is 1\times 10^{-5}.

4. Difference between the H^+ ions at both pH:

1\times 10^{-6} mol/L-1\times 10^{-11} mol/L=9.99\time 10^{-7} mol/L

This means that Hydrogen ions in a solution at pH = 7 has 9.99\time 10^{-7} mol/L ions fewer than in a solution at a pH = 6

What is the specific heat of a substance if 25 grams rises in temperature from 10 degrees Celsius to 25 degrees with the additio
Marina86 [1]

Answer:

0.75 cal/g°c

Explanation:

for specific heat we have formula:

Amount of heat absorbed or released = mass x specific heat of a substance x change in temperature.

ΔQ=m x c x ΔT

where c= specific heat

m= mass of a substance

ΔT = total temperature

ΔQ = Amount of heat

so for specific heat,

c= ΔQ/mxΔT

c= 280/25x (25-10)

c= 280/375

c= 0.75 cal/g°c

Compare the boiling points of 1-pentyne and 1-octyne.
Elan Coil [88]
1-pentyne consists of a carbon chain of 5 carbons one with a triple bond. 1-octyne is a carbon chain of 8 carbons with a triple bond at some point. It is known that the longer the carbon chain the higher the boiling point since more energy will be required to break the bonds between carbons. Based on this it is predicted that 1-octyne will have a higher boiling point than 1-pentyne.
