what is the molality of a solution in which 0.145 mol co2 (molar mass = 44.01 g/mol) is dissolved in 591 g water?

Answers

The molality of the solution is 0.010mole/kg.

Molality of a solution is the amount of the substance dissolved in the solvent. It is defined as the molar mass of the solute per 1kilogram of a solvent. Molar mass of the solvent is the amount of the compound divided by the amount of the substance .It is measured in moles.

We can calculate molality by dividing the amount of the solute by the mass of the solvent. Here amount of the solute calculated in moles and the mass of the solvent in grams.

          Molality= amount of the solute/mass of the solvent

      here, amount of the Co2 is 0.145 mole , molar mass is 44.01g/mole and   mass of the water is 591 g(0.59kg).

so, substituting all value in the expression of molality, we get,

            Molality=0.145* 0.044 /0.59kg

                           =0.010mole/kg

Answers

0.402 is the mole fraction of NaCl in a mixture of 0.564 g of NaCl, 1.52 g of KCl and 0.857 g of LiCl.

What is Mole Fraction ?

Mole fraction is defined as the given amount of moles divided by the total amount of the component in a mixture.

The formula for finding the mole fraction is

Mole Fraction = Moles of Component / Mole of total components

First we have to find the mole of NaCl

Moles of NaCl = Given Mass of NaCl/ Molar Mass of NaCl

= 0.564 gram/58.4 gram/mole

= 0.00965 mole

Now we have to find the mole of KCl

Moles of KCl = Given Mass of KCl/ Molar Mass of KCl

= 1.52 gram/74.55 gram/mole

= 0.0204 mole

Now we have to find the mole of LiCl

Moles of LiCl = Given Mass of LiCl / Molar Mass of LiCl

= 0.857 gram/42.39 gram/mole

= 0.0202 mole

Mole Fraction of the NaCl = Moles of NaCl/ Mole of NaCl + LiCl + KCl

= 0.00965/0.00965 + 0.0204 + 0.0202

= 0.192

Thus, from the above conclusion we can say that 0.402 is the mole fraction of NaCl in a mixture.

When gasoline is burned in a car engine, ________ energy is converted into _________ energy.





Answers

When gasoline is burned in a car engine, thermal energy is converted into mechanical energy.

What is energy conversion?

Energy conversion is the process by which energy is changed from forms supplied by nature to forms used by people.

For this goal, a huge variety of tools and systems have been created over the years. A few of these energy converters are really straightforward. Early windmills, for instance, used wind's kinetic energy to drive machinery that pumped water and ground grain.

Many of the forms that energy takes can be employed in natural processes. It also performs mechanical work to run the machines and offers various services to society, such as lighting, heating, and refrigeration. By applying pressure to the pistons and exerting work on them, the internal combustion engine of a car transforms the potential chemical energy in gasoline and oxygen into thermal energy, which is then translated into mechanical energy that drives the vehicle (raising its kinetic energy).

You can see that the vehicle engine converts the chemical energy that is contained in the fuel into the kinetic energy of expanding gas through combustion in the engine and the wheels. This is a practical energy transfer.

If a neutral atom loses one or more electrons, it will attain a positively charged cation whereas if a neutral atom gains one or more electrons, it will have a negatively charged anion.

Cations are positive ions. They are positively charged because they have lost one or more number of electrons and that's why it has more protons than electrons. Anions are negative ions.

Answers

The enthalpy of combustion of magnesium is -602KJ/mol

A combustion reaction is a reaction in which a substance reacts with the oxygen gas, releasing energy in the form of light and heat. Combustion reactions generally involves O2 as one reactant.

Heat capacity is defined as the amount of heat required to raise the temperature of the substance by one degree Celsius. Whereas the specific heat capacity of a substance is defined as the heat capacity per unit mass and it is measured in joules per kilogram per degree.

To calculate the heat absorbed by the calorimeter we use;

q = C × ΔT

q = 5760 × 0.570

q = 3283.2 J

So, 0.1326 grams of Magnesium releases energy q = 3283.2 J

Then 1 gram of Magnesium releases = 3283.2 ÷ 0.1326 = 24760 J/g

1 mol Mg = 24.31 grams

Hence, 1 mol Mg releases energy = 24.31 × 24760 = 601916 J/mol

⇒ 601.92 KJ/mol ≈ 602KJ/mol

Heat of combustion is always negative so, q = -602KJ/mol.

CF₄  is a tetrahedron with carbon at the center and fluorine at the four points. The dipole moments of the individual bonds cancel each other out.

Each of the other molecules is also a tetrahedron. Fluorine is more electronegative than chlorine, which is more electronegative than hydrogen. The dipole vector for each bond is the difference between the polarities of the two atoms. The dipole moment of the entire molecule is the vector sum of all of the individual bond dipole moments.

CF₄ and XeF₄ cancels itself out and has no dipole.

SF₄ on the other hand have The lone pair of electrons causes this compound to have a net dipole moment. It has no opposite pair of electrons that could cancel its pull, this results in it being polar.

therefore, CF₄ and XeF₄ are nonpolar compounds (have no net dipole moments) while SF₄ is polar (has a net dipole moment)

Element X is an element in period 5. Identify X given that in the molecule XF2, it exhibits hybridization sp3. Indicate the symbol and not the name of the element. Explain.

Answers

Group 5 Element X in the molecule XF2 is Sb.

Periodic table is the arrangement of the row and columns of the chemical elements. In the periodic table, period 5 contain 18 elements. These are Rb, sr, Y, Zr, Nb, Mo, Tc,Ru,Rh,Pd,Ag,Cd,In,Sn,Sb,Te,I,Xe.

The Sb atoms are hybridizes with sp3 to form a stable hexagon ring structure. Sb can act as a central atom in SbF2. In this structure it is bonded with 3 F molecule. This has no lone pair of electrons. Sb is a toxic chemical element. Its atomic number is 51.this is the additives for chlorine and bromine found in many commercial and domestic products.it improves the properties of the alloy.
