Calculate the ph of a solution having [OH-] = 8.2 x 10 ^-8M

Chemistry
1 answer:
egoroff_w [7]2 years ago
8 0

Answer:

<h2>6.91 </h2>

Explanation:

To find the pH we must first find the pOH

The pOH can be found by using the formula

pOH = - log [ {OH}^{-} ]

We have

pOH =  -  log(8.2 \times  {10}^{ - 8} )  \\  = 7.086186...

pOH = 7.09

Next we use the equation

pH = 14 - pOH

We have

pH = 14 - 7.09

We have the final answer as

<h3>6.91</h3>

Hope this helps you

Find the molarity of 750 ml solution containing 346 g of potassium nitrate
Zinaida [17]
Given mass of KNO₃=346g
Molar mass of KNO₃=(39.098)+(14)+(15.99*3)=101.068gmol⁻¹
Volume of Solution=750ml=0.75dm³

Molarity=(mass of solute/molar mass of solute)*(1/volume of sol. in dm³)
            =(346/101.068)*(1/0.75)
            =4.56 mol dm⁻³

Specify the hybridization at the atoms labelled a-d.
Nata [24]

The orbitals where you can find each of the bonds;

a - sp3

b - sp3

c - sp2

d- sp3

<h3>What is hybridization?</h3>

The term hybridization is the term that is used to describe the mixture of atomic orbitals which can be used to combine with other orbitals of relevant energy.

Let us recall that in some cases, the energy that is required in bonding could only be obtained by the hybridization of orbitals in which orbitals are mixed. The mixed orbitals are orbitals that are very close to each other in energy and help in the formation of bond.

Now let us try to write the orbitals where you can find each of the bonds;

a - sp3

b - sp3

c - sp2

d- sp3

Which sequence represents the relationship between temperature and volume as explained by the kinetic-molecular theory? higher t
Aleksandr-060686 [28]

Answer:

higher temperature → more kinetic energy → more space between particles higher volume

Explanation:

Kinetic Molecular Theory states that gas particles exhibit perfectly elastic collisions and remain in constant motion. Absolute temperature  is directly proportional to the average kinetic energy of gas particles.

The following sequence represents the relationship between temperature and volume as explained by the kinetic-molecular theory:

higher temperature → more kinetic energy → more space between particles higher volume
