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.

Explanation:

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]
