Answer:
The eluting strength of a solvent is primarily related to how strongly it adsorbs onto the adsorbent and because typical adsorbents are highly polar; thus, eluting strength increases with solvent polarity.
Explanation:
The polarity of a solvent makes it more suitable for elution in a polar adsorbent. Hence the choice of solvents should be in order of increasing rather than decreasing polarity. polarity must increase and not decrease
Answer:
you have a 3.17molal solution: This is 3.17mol CaCl2 dissolved in 1 litre of water. Make this solution.
Molar mass CaCl2 = 110.9848 g/mol
3.17mol = 3.17*110.9848 = 351.822g
Total mass = 1000g H2O + 351.822g CaCl2 = 1,351.822g
Volume of this solution:
Volume = mass / density
Volume = 1,351.822/1.24
Volume = 1,090.2 mL
You have 3.17mol CaCl2 dissolved in 1,090.2 mL solution
Mol CaCl2 dissolved in 1000mL solution = 1000/1090.2*3.17 = 2.91 mol CaCl2
Molarity of CaCl2 solution = 2.91M
Explanation:
Solids more dense in comparison.
The name of that product is 1-nonene.
The sufix ene is because it is an alkene, which comes from the fact that it has a double bond.
The prefix none is because it has 9 carbon.
And the use of number 1 is because the double bond is in the carbon number 1.
Answer : The energy of a photon is .
Solution : Given,
Frequency of a photon =
Planck' constant =
Formula used :
where,
E = Energy of a photon
h = Planck's constant
= Frequency of a photon
Now put all the given values in above formula, we get
Thus, the energy of a photon is .
