Answer:
![T'=30^{\circ} C](https://tex.z-dn.net/?f=T%27%3D30%5E%7B%5Ccirc%7D%20C)
Explanation:
Initial pressure, P = 125 kPa
Initial temperature, T = 25.0°C
If new pressure is increased to P' = 150.0 kPa
We need to find new temperature. According to Gay-Lussac's law,
P ∝ T
or
![\dfrac{P}{T}=\dfrac{P'}{T'}\\\\T'=\dfrac{P'T}{P}\\\\T'=\dfrac{150\times 25}{125}\\\\=30^{\circ} C](https://tex.z-dn.net/?f=%5Cdfrac%7BP%7D%7BT%7D%3D%5Cdfrac%7BP%27%7D%7BT%27%7D%5C%5C%5C%5CT%27%3D%5Cdfrac%7BP%27T%7D%7BP%7D%5C%5C%5C%5CT%27%3D%5Cdfrac%7B150%5Ctimes%2025%7D%7B125%7D%5C%5C%5C%5C%3D30%5E%7B%5Ccirc%7D%20C)
So, the new temperature will be
.
Answer:
London dispersion forces (LDF)
Explanation:
I had a test about this, so it should be right. Good Luck :D
Answer:
Tell students that sometimes when two (or more) substances are mixed together, a change occurs and another substance (or substances) is created. This is called a chemical reaction. Gas may form, heat may be produced, and color may change. These types of changes indicate that a chemical reaction has occurred.
Well first of all the atomic mass is the number of protons + the number of neutrons this is the mass of the nucleus and meaning that the protons and neutrons make up the nucleus which is where all the mass is located. So the number of protons will be equal to the number of electrons if it is a neutral atom. So the atomic number of Lithium is 3 and this is equal to the number of protons. So if you want to find the number of neutrons you have to subtract the number of protons which in this case is 3, so you're going to subtract 3 from 6 (6-3) and this is going to leave you with 3 neutrons. So in this case there are 3 Protons, 3 Neutrons, And 3 Electrons.
Answer:
An aqueous solution of
will be an acid and have a pH of less than 7.
An aqueous solution of
will be a neutral solution and have a pH equal to 7.
An aqueous solution of
will be an base and have a pH of more than 7.
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
pH scale generally runs from 1 to 14 where pH = 7 represents neutral medium, pH < 7 represents acidic medium and pH > 7 represents basic medium.
Thus,
<u>An aqueous solution of
will be an acid and have a pH of less than 7.</u>
<u>An aqueous solution of
will be a neutral solution and have a pH equal to 7.</u>
<u>An aqueous solution of
will be an base and have a pH of more than 7.</u>
