What is the pOH of a 7.5 x 10^-2 M H+ solution?

1 answer:

3 0

Well to go from H+ to pOH, you have to convert H+ to pH first.

H+ = <span>7.5 x 10^-2

Formula to get pH = pH= -log(H+)
Plug H+ in: pH= -log(7.5x10^-2)

pH= 1.125

now to get pOH we convert pH to pOH

formula for pOH= pOH=14-pH
plug pH in: pOH= 14- 1.125

Answer: 12.875

Hope this helps :)</span>

Calculate the poh of this solution. round to the nearest hundredth. ph = 1.90 poh =

Viktor [21]

Answer:

The answer is 5.10

Explanation:

<h3><u>Given</u>;</h3>

pH = 1.9

pOH = ?

We know that

pH + pOH = 7

pOH = 7 – pH

pOH = 7 – 1.90

pOH = 5.10

Thus, The pOH of the solution is 5.10

How did the surface area of the metal strip expose to the solution affect the

frez [133]

Answer:

See explanation below

Explanation:

In an electrochemical cell, electricity is obtained by the gradual deterioration of the anode.

Hence, surface area of the metal will affect the length of time within which the electrochemical cell works.

The greater the surface area of the metal, the longer the electrochemical cell can function and the greater the quantity of electricity produced, hence the answer above.

Draw the Lewis structure for the compound with the formula COCl2COCl2. Use lines to show bonding electrons.

stira [4]

Answer : The Lewis-dot structure of $COCl_2$ is shown below.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, $COCl_2$

As we know that carbon has '4' valence electrons, chlorine has '7' valence electron and oxygen has '6' valence electrons.

Therefore, the total number of valence electrons in $COCl_2$ = 1(4) + 2(7) + 1(6) = 24

According to Lewis-dot structure, there are 8 number of bonding electrons and 16 number of non-bonding electrons.
