The given question is incomplete. The complete question is:
A chemist prepares a solution of barium chloride by measuring out 110 g of barium chloride into a 440 ml volumetric flask and filling the flask to the mark with water. Calculate the concentration in mole per liter of the chemist's barium chloride solution. Round your answer to 3 significant digits.
Answer: Concentration of the chemist's barium chloride solution is 1.20 mol/L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L
moles of 
(solute) = 
Now put all the given values in the formula of molality, we get
Therefore, the molarity of solution is 1.20 mol/L
The attraction of an 
ion leads to the formation of an ionic bond with 
<h3>What is an ionic bond?</h3>
Ionic bond, also called an electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.
Since the question asking among all these options:
(a) The attraction of a noble gas
(b) The attraction of a 
ion
(c) The attraction of a group 1 element
(d) The attraction of a ion
An ionic bond can be formed after two or more atoms lose or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons.
Hence, option D is correct.

Answer:
<u>The amount of energy required to increase temperature 275°C to 385°C is ΔQ =3.95208kJ</u>
Explanation:
Given :
- <em>The mass of the water vapour is 18 g</em>
- <em>The initial temperature : 275°C</em>
- <em>The final temperature : 385°C</em>
According to the formula :
Δ
Δ
Where ,
- <em>Δ
is the heat supplied</em> - <em>
is the mass of the substance (water vapour) = 18g</em> - <em>
is the specific heat of the substance ( water vapour) = 
</em> - <em>Δ is the change in temperature =
</em>
∴
ΔQ = 
⇒ΔQ =3.95208kJ
