A solution has a pH = 4.63. What is the [H3O+] concentration?

Chemistry

LUCKY_DIMON [66]3 years ago
7 0

Explanation:

The pH of a solution can you be found by using the formula

pH = - log [ { H_3O}^{+}]

Since we are finding the [H3O+] , substitute the value of the pH and find it's antilog

We have

4.63 =  -  log[ { H_3O}^{+}] \\ [ { H_3O}^{+}]   =  {10}^{ - 4.63}  \\   \\  = 2.344 \times  {10}^{ - 5} mol {dm}^{ - 3}

Hope this helps you

Determine the hybrid orbital of this molecule.
Pavel [41]

The hybrid orbital of this molecule is sp^3. Hence, option C is correct.

<h3>What is hybridisation?</h3>

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

In this compound, sp^3 a hybrid orbital makes I-O bonds. Due to sp^3hybridization iodate should have tetrahedral geometry but because of the presence of lone pair of electrons the shape of IO^{3-} the ion is pyramidal.

The hybrid orbital of this molecule is sp^3. Hence, option C is correct.

Which type of change is represented?
pentagon [3]
The correct answer is A. The image shows a nuclear fission. This takes place in any of the heavy nuclei after capture of a neutron. This is the opposite of nuclear fusion. In this case, nuclei are broken down into two.
