What is the pH of a 3.9•10-8 M OH- solution

Mice21 [21]

POH will be -log[conc of OH]
-log (3.9E-08) = 7.409
pH = 14- pOH
pH = 14 - 7.409
pH = 6.59

For the reaction: 2H2O2 --> 2H2 + 2O2, what is the total number of moles of O2 produced from the complete decomposition of 8

Softa [21]

2 H₂O₂ --> 2 H₂ + 2 O₂

2 moles H₂O₂ ------> 2 moles O₂
8 moles H₂O₂ ------> ?

moles O₂ = 8 x 2 / 2

moles O₂ = 16 / 2

= 8 moles

Answer C

g If the titration of a 10.0-mL sample of sulfuric acid requires 28.15 mL of 0.100 M sodium hydroxide, what is the molarity of t

Leona [35]

Answer:

$M_{acid}=0.141M$

Explanation:

Hello,

In this case, the reaction between sulfuric acid and hydroxide is:

$H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O$

We can notice a 1:2 molar ratio between the acid and the base respectively, therefore, at the equivalence point we have:

$2*n_{acid}=n_{base}$

And in terms of volumes and concentrations:

$2*M_{acid}V_{acid}=M_{base}V_{base}$

So we compute the molarity of sulfuric acid as shown below:

$M_{acid}=\frac{M_{base}V_{base}}{2*V_{acid}} =\frac{0.100M*28.15mL}{2*10.0mL}\\ \\M_{acid}=0.141M$

Best regards.
