(100 POINTS!!!!) In one to two sentences, describe the process by which the ionic compound, LiCl, would dissolve in the polar solvent, CH3COCH3

Answers

Answer 1

Answer:

LICL as an Ionic compounds has covalent ability and they are soluble in polar solvent such as CH3COCH3 but they are insoluble in non-polar solvents. Due to their polarity, CH3COCH3 will decreases the electrostatic forces of attraction thereby resulting in free ions in aqueous solution.

Water is the known as a polar solvent that can dissolve an ionic compounds very easy and as a polar solvent, the arrangement of oxygen and hydrogen atoms in water is in bent shape.

Ionic compounds like LICL that is very polar is soluble in the polar solvent water.

Polar solvents like CH3COCH3 will dissolve polar and ionic solutes because of the attraction of the opposite charges on the solvent and solute particles.

How many grams of sodium chloride are dissolved in 375 ml of a 0.90% saline solution?

Answers

Answer:

337.5 g NaCl

Explanation:

.90% saline solution = 90g saline (NaCl)/100mL water (H2O)

1. Use 375 mL to find mass

375 mL × (90 g NaCl/100 mL) = 337.5 g NaCl in 375 mL .9% saline solution

The amount of sodium chloride dissolved in 375 ml of a 0.90% saline solution is 337.5 g.

What is the concentration of the solution?

The concentration can be calculated when we have the molecular formula and its molecular weight. The concentration of the solution is calculated as the weight of a solute divided by the volume of the solution.

The weight/volume percentage of the solution is determined in the following way.

W/v (%) = weight of the solute/Volume of the Solution ( in mL)

Given, the concentration of the saline solution = 0.90 %

0.90 % saline solution means 90 g of NaCl is dissolved in 100 ml of water.

Given, the volume of solution = 375 ml

100 ml of saline solution containing NaCl = 90 g

Then 375 ml of saline solution containing NaCl = 90 ×375/100 = 337.5 g

Therefore, the amount of NaCl is equal to 337.5 g.

a hot air balloon has a volume of 875L. what is the original temperature of the balloon if its volume changes to 955 L when heated to 56

Answers

Answer:

using Charles law

v1/t1= v2/ t2

Explanation:

875/t1=955/56+273

t1= 329* 875/955

t1= 302.82k

The initial temperature of the hot air balloon can be calculated from Charles's law. The initial temperature of the balloon was, 51.3 °C.

What is Charles's law?

According Charles's law, at constant pressure, the temperature and volume of a gas is in direct proportionality. Thus volume increases with an increase in temperature. Therefore V/T = a constant.

Let V₁ and T₁ be the initial volume and initial temperature and V₂ and T₂ be the final volume and temperature respectively. Thus we can write the relation as:

V₁ /T₁  = V₂/T₂ .

Given that the initial and final volume are 875 L and 955 L respectively. The final temperature is 56 °C. Thus the initial temperature is calculated as :

T₁ = V₁T₂/V₂

   = (875 L × 56 °C )/955 L

   = 51.3 °C.

Hence, the initial temperature of the hot air balloon was 51.3 °C.

Magnesium metal is reacted with hydrochloric acid to produce hydrogen gas. A sample of hydrogen gas is collected over water in a eudiometer at 28.0°C. The atmospheric pressure is 786 mmHg. Determine the pressure (in atm) of the hydrogen gas produced.

Answers

The pressure of hydrogen gas produced is 0.997 atm

Using the standard table of temperature and water vapour pressure;

At 28.0°C, the water vapour pressure = 28.3 mmHgThe pressure of hydrogen gas (H₂) collected over water is:= [tex]\mathbf{P_{moist\ gas } = 786 mmHg}[/tex]

Recall that:

[tex]\mathbf{P_{moist \ gas} = P_{dry \ gas} + P_{water vapor}}[/tex]

where;

the dry gas = hydrogen gas

[tex]\mathbf{ P_{dry \ gas} = P_{moist \ gas} - P_{water vapor}}[/tex]

[tex]\mathbf{ P_{dry \ gas} = (786- 28.3) mmHg}}[/tex]

[tex]\mathbf{ P_{dry \ gas} = (757.7) mmHg}}[/tex]

We know that 1 atmospheric pressure = 760 mmHg

757.7 mmHg will be:

[tex]\mathbf{=\dfrac{757.7 \ mmHg \times 1 \ atm}{760 \ mmHg}}[/tex]

= 0.997 atm

Therefore, we can conclude that the pressure of hydrogen gas produced is 0.997 atm

Did all the silver ions get consumed in the reaction? The molar mass of silver is 107.87 g/mol. Justify your answer.

Answers

This problem is asking for the consumption of silver ions when silver nitrate is reacted with copper. In such a case, since no masses are given, we can use the following from similar problems:

Mass of empty beaker: 110.000 g

Mass of beaker with silver nitrate (after all additions) and copper: 331.634 g.

Mass of beaker with silver: 113.395 g.

This means we can write the following chemical equation:

[tex]Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag[/tex]

And thus calculate the mass of silver nitrate that will produce the following mass of silver:

[tex]m_{Ag}^{produced}=113.395g-110.000g=3.395g[/tex]

Next, we use the 2:2 mole ratio of silver to silver nitrate (silver ions source):

[tex]3.395gAg*\frac{1molAg}{107.87gAg}*\frac{2molAgNO_3}{2molAg} *\frac{169.87gAgNO_3}{1molAgNO_3} = 5.35gAgNO_3[/tex]

The step will be defined for the given mass of available silver nitrate which will be compared to 5.35 g (consumed mass) to see if they are the same (all consumed) or different (partial consumption).

8) What mass of chlorine reacts with 20.0 g of iron to form iron(III) chloride?​

Answers

Answer:

38.3 g

Explanation:

8) What mass of chlorine reacts with 20.0 g of iron to form iron(III) chloride?​

first write, then balance the equation

Fe + Cl2-------------> FeCl3

2Fe + 3Cl2----------> 2FeCl3

2 moles of Fe require 3 moles of Cl2

the atomic mass of Fe is 56

20/56= 0.36 moles of Fe

this requires o.36 X 3/2 = 0.54 moles of Cl2

Cl2 has a molar mass of 35.5 X 2=71

1 mole of Cl2 is 71g

0.54 moles is 0.54 X 71 g= 38.3 g

The mass of chlorine reacts with 20.0 g of iron to form iron(III) chloride is 38.3 g.

What is mass?

Mass is defined as a numerical representation of the fundamental characteristic of all matter, inertia.

It can also be defined as a dimensionless number used to describe the mass of a particle or item.

[tex]\rm 2Fe + 3Cl_2\rightarrow2FeCl_3[/tex]

As per the reaction 3 mole of chlorine is required for 2 mole of fluorine.

Atomic mass of fluorine = 56

Moles of Fe = 20 / 56

                    =  0.36 moles

This require 0.36 x 3/2 = 0.54 moles of Cl₂

Molar mass of Cl = 35.5

So for Cl₂ = 2 x 35.5 = 71 moles

For 1 mole of Cl₂ = 71 moles is needed

So, for 0.54 moles = 71 x 0.54

                               = 38.3 g

Thus, the mass of chlorine reacts with 20.0 g of iron to form iron(III) chloride is 38.3 g.
