Answer:

The correct answer is - anhydrous aluminum chloride is covalent whereas anhydrous magnesium chloride is ionic.

Explanation:

Anhydrous aluminum chloride is a covalent compound and we know that covalent compounds have less or no polarity. Organic compounds or solvents are mostly non-polar in nature. And it is a thumb rule that like-dissolves-like.

Thus they dissolve covalent molecules like anhydrous aluminum chloride.

Anhydrous magnesium chloride is an ionic compound that tends to interact with a polar solvent but not in a non-polar solvent such as organic solvents.

Anhydrous aluminum chloride is fairly soluble in the organic solvent while anhydrous magnesium chloride is insoluble​ because anhydrous aluminum chloride is covalent whereas anhydrous magnesium chloride is ionic.

AlCl3 quite simply accepts electrons from other atoms, in an try and get a full valence shell of eight electrons. It's why it normally behaves as a Lewis acid. In the response under, the Al atom accepts a lone pair of electrons from a Cl atom.

AlCl3 is hygroscopic and has a great affinity for water. Therefore, aluminum chloride dissolves in water partially.

V2= 1.03L

Explanation:

Start off with what you are given.

V^1: 1.00L

T^1: 23°C

V^2?

T^2: 33°C

If you know your gas laws, you have to utilise a certain gas law called Charles' Law:

V^1/T^1 = V^2/T^2

Remember to convert Celsius values to Kelvin whenever you are dealing with gas problems. This can be done by adding 273 to whatever value in Celsius you have.

(23+273 = 296)     (33+273 = 306)

Multiply crisscross

1.00/296= V^2/306

296V^2 = 306

Dividing both sides by 296 to isolate V2, we get

306/296 = 1.0337837837837837837837837837838

V2= 1.03L

[tex]V_2=120L[/tex]

Explanation:

Hello!

In this case, since Helium is undergoing a volume-pressure change, according the Boyle's law, we infer the following equation is used:

[tex]P_1V_1=P_2V_2[/tex]

Thus, since we are not given the volume at 0.25 atm, we can solve for V2 to do so:

[tex]V_2=\frac{P_1V_1}{P_2}[/tex]

Thus, we plug in to obtain:

[tex]V_2=\frac{1atm*30L}{0.25atm}=120L[/tex]

Best regards!

The final volume of the balloon at the given altitude is 120 L.

The given parameters;

The final volume of the balloon at the given altitude is calculated by applying Boyles law as follows;

[tex]P_1 V_1 = P_2 V_2\\\\V_2 = \frac{P_1V_1}{P_2} \\\\V_2 = \frac{30 \times 1 }{0.25} \\\\V_2 = 120 \ L[/tex]

Thus, the final volume of the balloon at the given altitude is 120 L.

a. 0.68 M NaCl solution

Explanation:

The tonicity of a solution can either be hypotonic, hypertonic and isotonic. Hypertonic solution is a solution which possesses a higher concentration of solute in relation to another solution.

According to this question, a solution is said to contain 0.15 M NaCl solute. This means that a solution that will be hypertonic to this solution will have a much more concentration of solute, which based on the options provided is the 0.68 M NaCl solution.

Answer:

1860 torr

Explanation:

In order to convert from kPa to torr, we are going to use the following conversion factor:

Now we multiply 248 kPa with this factor so that the kPa units cancel each other and only the torr units remain:

This means that the answer is 1860 torr.

Answer:

(a). 4°C, (b). 2.4M, (c). 11.1 g, (d). 89.01 g, (e). 139.2 g and (f). 58 g/mol.

Explanation:

Without mincing words let's dive straight into the solution to the question.

(a). The freezing point depression can be Determine by subtracting the value of the initial temperature from the final temperature. Therefore;

The freezing point depression = [ 1 - (-3)]° C = 4°C.

(b). The molality can be Determine by using the formula below;

Molality = the number of moles found in the solute/ solvent's weight(kg).

Molality = ( 11.1 / 58) × (1000)/ ( 90.4 - 11.1) = 2.4 M.

(c). The mass of acetone that was in the decanted solution = 11.1 g.

(d). The mass of water that was in the decanted solution = 89.01 g.

(e). 2.4 = x/ 58 × (1000/1000).

x = 2.4 × 58 = 139.2 g.

(f). The molar mass of acetone = (12) + (1 × 3) + 12 + 16 + 12 + (1 x 3) = 58 g/mol.

Answer:

B.) P4

Explanation:

Step 1: Convert 25.0 grams of phosphorus into moles of phosphorous:

25 g P4 x 1 mol P4/123.90 g P4 = 0.202 mol P4

Step 2: Convert 0.202 mol P4 into moles of O2 using their stoichiometric ratios:

0.202 mol P4 x 5 mol O2/1 mol P4 = 1.01 mol O2

Step 3: Convert 1.01 mol O2 into grams of O2:

1.01 mol O2 x 31.98 g O2/1 mol O2 = 32.3 g O2

Because 25.0 grams of phosphorous only needs 32.3 grams of oxygen to react, phosphorous will be the limiting reactant, as after the 25.0 grams of phosphorous is used up, there will still be 17.7 grams of oxygen leftover (excess reactant).

Because the reaction cannot occur without more phosphorous to react with the 17.7 grams of oxygen remaining, P4 is the limiting reactant.

Answer:  B.) P4

Explanation:

        25 g P4 x 1 mol P4/123.90 g P4 = 0.202 mol P4

        0.202 mol P4 x 5 mol O2/1 mol P4 = 1.01 mol O2

        1.01 mol O2 x 31.98 g O2/1 mol O2 = 32.3 g O2

Because 25.0 grams of phosphorous only needs 32.3 grams of oxygen to react, phosphorous will be the limiting reactant, as after the 25.0 grams of phosphorous is used up, there will still be 17.7 grams of oxygen leftover (excess reactant).

Answer:

Explanation:

mole of HCl remaining after reaction with CaCO₃

= .3 M of NaOH of 32.47 mL

= .3 x .03247 moles

= .009741 moles

Initial HCl taken = .3 x .005 moles = .0015 moles

Moles of HCl reacted with CaCO₃

= .009741 - .0015 = .008241 moles

CaCO₃     +    2HCl   =   CaCl₂  +  CO₂  +  H₂O .

1 mole        2 moles

2 moles of HCl reacts with 1 mole of  CaCO₃

.008241 moles of HCl reacts with .5 x .008241 moles of  CaCO₃

CaCO₃ reacted with HCl =  .5 x .008241 = .00412 moles

the mass (in grams) of calcium carbonate in the tablet

= .00412 x 100 = .412 grams . ( molar mass of calcium carbonate = 100 )

We have that  the mass (in grams) of calcium carbonate in the tablet  is mathematically given as

mass of  CaCO₃= 0.412 grams

Question Parameters:

Generally the equation for the mole of HCl  is mathematically given as

mole of HCl = 0.3 M of NaOH of 32.47 mL

mole of HCl= 0.3 x 0.03247 moles

mole of HCl= 0.009741 moles

Therefore

Initial HCl taken = 0.3 x 0.005 moles

Initial HCl taken= 0.0015 moles

Moles of HCl reacted with CaCO₃

M_{hcl}= 0.009741 - .0015

M_{hcl}= .008241 moles

The Chemical Equation

CaCO₃     +    2HCl   =   CaCl₂  +  CO₂  +  H₂O .

Therefore, CaCO₃ reacted with HCl is

CaCO₃ reacted with HCl=  0.5 x 0.008241

 CaCO₃ reacted with HCl= .00412 moles

Hence,the mass of   CaCO₃ is

mass of   CaCO₃ = 0.00412 x 100

mass of   CaCO₃= 0.412 grams
