What is the pH if the [H+] concentration is 3 x10^-13​

Chemistry
1 answer:
Shkiper50 [21]3 years ago
6 0

Answer:

pH = 12.52

Explanation:

Given that,

The [H+] concentration is 3\times 10^{-13}.

We need to find its pH.

We know that, the definition of pH is as follows :

pH=-log[H^+]

Put all the values,

pH=-log[3\times 10^{-13}]\\\\pH=12.52

So, the pH is 12.52.

A neutral atom possesses an atomic number of 15 and an atomic mass of 31. Three electrons are gained. What is the result of this
Katyanochek1 [597]

<em>Answer:</em> an anion will form with -3 charge.


<em>Explanation;</em>


The atomic number of the given atom = 15


Atomic number = number of protons


The number of protons of the given atom = 15


The atomic mass of the given atom = 31


Atomic mass = number of protons + number of neutrons

Hence,

   number of neutrons = atomic mass - number of protons

                                      = 31 - 15

                                      = 16


Since, the atomic number is 15, the given atom is P which has the atomic number as 15.


In the neutral compound,

           number of protons = number of electrons

Hence,

           the number of electrons of the neutral atom = 15


But, the atom has gained 3 electrons.


Gaining of electrons will form anions.


Hence, the atom will be converted into anion which has -3 charge on it.


But the atomic mass, atomic number, number of protons and number of electrons will not be changed

Imagine a pair of wet pants. Explain what will most likely happen to the pants' index of refraction when they dry out. Support y
aniked [119]

Plants maintain water balance by opening and by closing stomata.

Explanation:

When plants are not getting enough water the tips as well as the edges of the leaves start drying and ultimately it turns brown in color. And when all the leaves turn brown the plant ultimately dies.

When light is travelling from the air to the water , the movement slows down and thus there is a little change in the direction. Thus we can say a light bend occurs when the light moves towards denser medium.
