What is the Bond Type OF CaCl2
1. What is the Bond Type OF CaCl2
Answer:
ionic bond
Explanation:
CaCl2 or Calcium Chloride is an ionic bond and not a covalent bond. Since there should be sharing of electrons between two atoms to be a covalent bonding. In case of calcium chloride, the calcium gives up an electron to each chlorine atom, becoming Ca2+ ions and chlorine become Cl– ions.

21. A solution is prepared by dissolving 23.7 g of CaCl2 in 375 g water. The density of the resulting solution is 1.05 g/ml. Calculate the (a) percent by weight CaCl2 ; (b) molality; (c) mole fraction of CaCl2 in the solution
(a) SOLUTION:
Step 1: List the given values.
[tex]\begin{aligned} & mass_{\text{solute}} = \text{23.7 g} \\ & mass_{\text{solvent}} = \text{375 g} \end{aligned}[/tex]
Step 2: Calculate the percent by weight.
[tex]\begin{aligned} \%(w/w) & = \frac{mass_{\text{solute}}}{mass_{\text{solute}} + mass_{\text{solvent}}} \times 100\% \\ & = \frac{\text{23.7 g}}{\text{23.7 g + 375 g}} \times 100\% \\ & = \boxed{5.94\%} \end{aligned}[/tex]
Hence, the %(w/w) of CaCl₂ is 5.94%.
------------------------------------------------------------
(b) SOLUTION:Step 1: List the given values.
[tex]\begin{aligned} & mass_{\text{solute}} = \text{23.7 g} \\ & MM_{\text{solute}} = \text{110.978 g/mol} \\ & mass_{\text{solvent}} = \text{375 g = 0.375 kg} \end{aligned}[/tex]
Step 2: Calculate the number of moles of solute.
[tex]\begin{aligned} n_{\text{solute}} & = \frac{mass_{\text{solute}}}{MM_{\text{solute}}} \\ & = \frac{\text{23.7 g}}{\text{110.978 g/mol}} \\ & = \text{0.213556 mol} \end{aligned}[/tex]
Step 3: Calculate the molality of solution.
[tex]\begin{aligned} m & = \frac{n_{\text{solute}}}{mass_{\text{solvent}}} \\ & = \frac{\text{0.213556 mol}}{\text{0.2029 kg}} \\ & = \text{0.569 mol/kg} \\ & = \boxed{0.569 \: m} \end{aligned}[/tex]
Hence, the molality of the solution is 0.569 m.
------------------------------------------------------------
(c) SOLUTION:Step 1: List the given values.
[tex]\begin{aligned} & mass_{\text{solute}} = \text{23.7 g} \\ & MM_{\text{solute}} = \text{110.978 g/mol} \\ & mass_{\text{solvent}} = \text{375 g} \\ & MM_{\text{solvent}} = \text{18.015 g/mol} \end{aligned}[/tex]
Step 2: Calculate the number of moles of each component.
• For solute (CaCl₂)
[tex]\begin{aligned} n_{\text{solute}} & = \frac{mass_{\text{solute}}}{MM_{\text{solute}}} \\ & = \frac{\text{23.7 g}}{\text{110.978 g/mol}} \\ & = \text{0.213556 mol} \end{aligned}[/tex]
• For solvent (water)
[tex]\begin{aligned} n_{\text{solvent}} & = \frac{mass_{\text{solvent}}}{MM_{\text{solvent}}} \\ & = \frac{\text{375 g}}{\text{18.015 g/mol}} \\ & = \text{20.816 mol} \end{aligned}[/tex]
Step 3: Calculate the mole fraction of solute.
[tex]\begin{aligned} X_{\text{solute}} & = \frac{n_{\text{solute}}}{n_{\text{solute}} + n_{\text{solvent}}} \\ & = \frac{\text{0.213556 mol}}{\text{0.213556 mol + 20.816 mol}} \\ & = \boxed{0.0102} \end{aligned}[/tex]
Hence, the mole fraction of CaCl₂ is 0.0102.

22. is CaCl2 covalent or not?
Answer:
Not
Explanation:
CaCl2 or Calcium Chloride is an ionic bond and not a covalent bond. Since there should be sharing of electrons between two atoms to be a covalent bonding.
23. 20g of CaCl2 is enough to dissolve in 56L.What is the molarity?
The answer is 3 M or 3 mol/L
solution:
MCaCl2= wt* solute/(MM* solute)(L of solution)
Note:
MCaCl2 is Molarity of CaCl2 ( I like to do my equations like this, I hope you don't mind )
MM is Molecular mass and wt is weight
- We'll be using this formula because the number of moles were not given.
MCaCl2= 20g/(111 g/mol)(56 L)
- Just cancel grams so you'll be left with mol/L
MCaCl2= 3.2175...
MCaCl2= 3 M or 3 mol/L
-It is only 3 because the least number of significant figures is 1. 20g is 1 SF, 56 L is 2 SF, and 111 g/mol is 3 SF.
I hope this help! Good Luck and listen well to your Chem teacher/professor it'll get harder especially when you guys go to Rate of Reaction, Chemical Equilibrium, Le Chatlier's principle and so on ( not scaring you guys but take this is as an advice XD )
24. 11. Determine the molar mass of CaCl2.
Answer:
Since the molar mass of Calcium is 40.08 g and the molar mass of Chlorine is 35.45, it would be 40.08g+35.45g+35.45g (with 2 Chlorines according to the subscript.) That leaves you with 110.98 g.

27. Calculate the molal concentration of a 20.0% aqueous solution of CaCl2
Good Day
Problem:
Calculate the molal concentration of a 20.0% aqueous solution of CaCl₂
Given:
20.0% aqueous solution of CaCl2
It means 20 grams of solute in 100 grams solution, thus it have
20 g of CaCl₂ and 80 g of water.
Moles of Solute :
1 mole of CaCl2 contains 110.98 grams
20 g × 1 mole/110.98 g = 0.18 moles
Kg of Solvent:
80 g of water
80 g × 1 Kg / 1000 g = 0.08 kg
Solution:
The formula for Molality: m = moles of solute / kg of sovent
m = moles of solute / kg of sovent
= 0.18 moles / 0.08 kg
= 2.25 m
Answer:
molal concentration of a 20.0% aqueous solution of CaCl₂ is 2.25 m

30. Solid lime (CaO) dissolves in HCl to form CaCl2 and H2O).How many grams of HClag) are needed to make 100 g of CaCl2s)?
Solution:
Step 1: Write the balanced chemical equation.
CaO (s) + 2HCl (aq) → CaCl₂ (s) + H₂O (l)
Step 2: Calculate the molar mass of HCl and CaCl₂.
For HCl
molar mass = (1.008 g/mol × 1) + (35.45 g/mol × 1)
molar mass = 36.458 g/mol
For CaCl₂
molar mass = (40.08 g/mol × 1) + (35.45 g/mol × 2)
molar mass = 110.98 g/mol
Step 3: Determine the mole ratio needed.
mole ratio = 2 mol HCl : 1 mol CaCl₂
Step 4: Calculate the mass of HCl needed using the mole ratio.
[tex]\text{mass of HCl = 100 g CaCl₂} × \frac{\text{1 mol CaCl₂}}{\text{110.98 g CaCl₂}} × \frac{\text{2 mol HCl}}{\text{1 mol CaCl₂}} × \frac{\text{36.458 g HCl}}{\text{1 mol HCl}}[/tex]
[tex]\boxed{\text{mass of HCl = 65.7 g}}[/tex]
