Answer : The electronic configuration of argon (Ar) is, 
Explanation :
Element is, Argon (Ar)
Atomic number of argon = 18
The number of electrons = 18
As we know that the number of electrons is equal to the number of protons and the number of proton is equal to the atomic number.
Electronic configuration : It is defined as the arrangement or distribution of electron of atom in a atomic orbital.
Hence, the electronic configuration of argon is,
Yea ion know i just want sun point lol o m g is it rekutten ;)
Answer:
Explanation:
1. Find the molar concentration
Assume that we have 100 mL solution.
Mass of NaCl = 0.90 g
2. Find the osmotic pressure
The formula for osmotic pressure (Π) is
Π = icRT
T = (37 + 273.15) K = 310.15 K
Answer:
A
Explanation:
an element contains only one kind of particle
Answer is: A. solute
.
Solvation is the interaction of solvent (in this example water) with molecules or ions (in this example carbon dioxide)) in a solute.
Solvent (usually a liquid, but can also be a solid or a gas) is a substance that dissolves a solute (dissolved in the solvent).
Solvent is always the same state of matter as the solution. In this example, soft drink is a liquid, so water is a solvent.
