The attraction forces between mercury atoms in liquid mercury are stronger than the intermolecular forces between water molecules because it has a higher surface tension than does water.

Surface tension is the propoerty of the surface of liquids by which they will shrink into the minimum possible surface area.

Surface tension of the liquid mercury is greater than the surface tension of water means cohesive attraction force between the molecules of mercury is greater than water molecules.

Hence option (A) is correct.

Explanation:

Answer:

C. The temperature at which the solution freezes is lowered.

The solubility of the gas if the pressure is changed to 100 kPa is 0.742 g/L

As the pressure of a gas increases, the solubility increases, and as the pressure of a gas decreases, the solubility decreases.

Thus, Solubility varies directly with Pressure

If S represents Solubility and P represents Pressure,

Then we can write that

S ∝ P

Introducing proportionality constant, k

S = kP

S/P = k

∴ We can write that

[tex]\frac{S_{1} }{P_{1} } = \frac{S_{2} }{P_{2} }[/tex]

Where [tex]S_{1}[/tex] is the initial solubility

[tex]P_{1}[/tex] is the initial pressure

[tex]S_{2}[/tex] is the final solubility

[tex]P_{2}[/tex] is the final pressure

From the given information

[tex]S_{1} = 0.890 \ g/L[/tex]

[tex]P_{1} = 120 \ kPa[/tex]

[tex]P_{2} = 100 \ kPa[/tex]

Putting the parameters into the formula, we get

[tex]\frac{0.890}{120}=\frac{S_{2}}{100}[/tex]

[tex]S_{2}= \frac{0.890 \times 100}{120}[/tex]

[tex]S_{2}= 0.742 \ g/L[/tex]

Hence, the solubility of the gas if the pressure is changed to 100 kPa is 0.742 g/L

The balanced chemical equation for the reaction between barium hydroxide, Ba(OH)₂ and HNO₃ to produce barium nitrate, Ba(NO₃)₂ is

Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + 2H₂O

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

Ba(OH)₂ + HNO₃ —> Ba(NO₃)₂ + H₂O

There are 2 atoms of N on the right side and 1 atom on the left side. It can be balanced by writing 2 before HNO₃ as shown below:

Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + H₂O

There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balanced by writing 2 before H₂O as shown below

Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + 2H₂O

The molar mass of gas sample whose mass is 7.9g at Standard temperature and pressure is 26.4 g/mol.

Molar mass of any substance will be calculated by using the below equation:

M = W/n, where

M = molar mass

W = given mass

n = moles

First we calculate the moles of gas by using the ideal gas equation:

PV = nRT, where

P = standard pressure = 1 atm

V = volume = 6.7 L

n = moles of gas?

R = universal gas constant = 0.082 L.atm/K.mol

T = absolute temperature = 273K

On putting values, we get

n = (1)(6.7) / (0.082)(273)

n = 0.299 moles

Now we get the molar mass of gas by putting values on the first equation, we get

M = 7.9g / 0.299mol = 26.4 g/mol

Hence molar mass of given gas is 26.4 g/mol.

Answer:

Explanation:

In PbO

2

​

, oxygen exhibits an oxidation number of −2 (since it's not a peroxide or superoxide).

Let the oxidation number of Pb be x. Then, for the compound to be neutral, the oxidation numbers of all atoms should add up to zero.

⇒x+(−2)+(−2)=0

     x=+4

So the oxidation no. of Pb is +4.

The lead (Pb) oxidation number in [tex]\rm PbO_2[/tex] is +4, whereas the oxygen (O) oxidation number is -2.

The idea of oxidation number, also known as oxidation state, is used in chemistry to describe the potential charge that an atom would have if electrons were completely transported in a chemical bond or reaction. It is a valuable instrument for tracking electron distribution in a chemical or ion and understanding redox (oxidation-reduction) reactions. Understanding redox processes, which involve the transfer of electrons between reactants, requires an understanding of oxidation numbers.

Oxidation number of Pb is given as:

(+x) + 2(-2) = 0

x - 4 = 0

x = +4

When a liquid is heated, the average kinetic energy of its particles will increase.

The ability to do work is called as energy. Work done is product of force and displacement. Energy is of different types as sound energy, kinetic energy, potential energy, electrical energy, light energy etc.

Law of conservation of energy states that energy can neither be created nor destroyed, but it can be transferred from one form to another.

Molecules can move so they show kinetic energy, molecules can be there at many positions so they can show potential energy, molecules can vibrate so they can show sound energy but molecules can only absorb light hence they can't have light energy.

Average kinetic energy = 3KT/2

If temperature increases, kinetic energy also increases.

Therefore, When a liquid is heated, the average kinetic energy of its particles will increase.
