Answer:
Vapor pressure of water = 23.14torr
Explanation:
When you made a solution, vapor pressure decreases following Raoult's law:

<em>Where P is vapor pressure and X mole fraction</em>
As vapor pressure of water is 23.77torr we must find the mole fraction of water knowing the solution is 1.500m glucose (That is 1.500 moles of glucose per kg of water = 1000g of water).
1000g of H₂O are, in moles (Molar mass: 18.02g/mol):
1000g H₂O ₓ (1mole / 18.02g) = 55.5 moles of H₂O.
As we know now the solution contains 55.5 moles of water and 1.5 moles of glucose. Thus, mole fraction of water (Solvent) is:

Replacing in Raoult's law, pressure of water above the solution is:


<h3>Vapor pressure of water = 23.14torr</h3>
Answer: The electronic configuration of Chlorine will be ![[Ne]3s^23p^5](https://tex.z-dn.net/?f=%5BNe%5D3s%5E23p%5E5)
Explanation: Chlorine is an element which belongs to the P-block of the periodic table. Its atomic number is 17.
Atomic Number = Number of electrons
Number of electrons = 17
The nearest noble gas which lies to Chlorine is Neon which has 10 electrons. Rest of the 7 electrons are filled in the 3s and 3p orbitals. Hence, the electronic configuration of Chlorine is
![[Cl]=[Ne]3s^23p^5](https://tex.z-dn.net/?f=%5BCl%5D%3D%5BNe%5D3s%5E23p%5E5)
Bello,
I think the answer is A

Catalysts are substances that speed up the rate of a chemical
reaction. It is important to know that reacting species must first possess a
minimum amount of energy equal to the activation energy for the reaction
to proceed. The catalyst works in a way that lowers the activation energy
required for the reaction to proceed. In this way, the reaction occurs at a
faster rate than without a catalyst. Catalysts do not react with
the chemical species in the reaction, thus, they are not consumed. However, over
time, catalysts tend to degrade and their function is also reduced. When this
happens, new catalysts replace the poisoned ones. Catalysts are widely used
today since they bring an increase in the production rate of commercial chemicals.
