Answer:

0.468 m

Explanation:

From the question given above, the following data were obtained:

Mass of napthalalene (C₁₀H₈) = 30 g

Mass of toulene = 500 g

Molality =?

Next, we shall determine the number of mole in 30 g of C₁₀H₈. This can be obtained as follow:

Mass of C₁₀H₈ = 30 g

Molar mass of C₁₀H₈ = (12×10) + (8×1)

= 120 + 8

= 128 g/mol

Mole of C₁₀H₈ =?

Mole = mass / molar mass

Mole of C₁₀H₈ = 30 / 128

Mole of C₁₀H₈ = 0.234 mole

Next, we shall convert 500.0 g of toulene to Kg. This can be obtained as follow:

1000 g = 1 Kg

Therefore,

500 g = 500 g × 1 Kg / 1000 g

500 g = 0.5 Kg

Finally, we shall determine the molality of the solution. This can be obtained as follow:

Mole of solute (C₁₀H₈) = 0.234 mole

Mass of solvent (toulene) = 0.5 Kg

Molality =?

Molality = mole of solute / Kg of solvent

Molality = 0.234 / 0.5

Molality = 0.468 m

Answer:

The key to understanding water's chemical behavior is its molecular structure. A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons

Answer:

20.02 Liters

Explanation:

Mass = 35g

Volume = ?

Temperature = 301K

Pressure = 1.35 atm

The relationship between the quantities is given as;

PV =  nRT

n = mass / Molar mass = 35 / 32 = 1.09375 mol

V = nRT / P

V = (1.09375 * 0.0821 * 301) / 1.35

V = 20.02 L

Answer:

b. proton

Explanation:

The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1, which is equal but opposite to the charge of a proton, which is +1.

Answer:

Mass of the second spaceship is 3.10 × 10⁴ kg 0r 31000 kg

Explanation:

From Newton's law of universal gravitation, the force of attraction , F, between two bodies is directly proportional to the product of their masses and inversely proportional to the square root of the distance between them.

F = Gm₁m₂/d²

m₁ = 24000 kg

m₂ = ?

d = 300 m

F = 5.51 × 10⁻⁷ N

Gravitational constant,  G = 6.67 × 10⁻¹¹ N.m²/kg²

Making m₂ subject of the formula : m₂ = F × d² / G × m₁

m₂ = 5.51 x 10⁻⁷ × 300 × 300 / 6.67 × 10⁻¹¹ × 24000

m₂ = 3.1 × 10⁴ kg

Therefore, Mass of the second spaceship is 31000 kg

Answer:

moist air is less dense than dry air because water has a lower molecular weight than nitrogen and oxygen

Answer:

Water vapor is a relatively light gas when compared to diatomic Oxygen and diatomic Nitrogen. Thus, when water vapor increases, the amount of Oxygen and Nitrogen decrease per unit volume and thus density decreases because mass is decreasing.

Answer:

Soil is a mixture of minerals, dead and living organisms (organic materials), air, and water.

Explanation:

Dead organisms decompose(kind of like fertilizer)

water comes from nearby watersheds, precipitation processes, etc.

Answer:

Soil is made up of three main components – minerals that come from rocks below or nearby, organic matter which is the remains of plants and animals that use the soil, and the living organisms that reside in the soil. The proportion of each of these is important in determining the type of soil that is present.

Explanation:

Radiation from alpha decay has the least energy.

Alpha decay is the name for the nuclear process that releases alpha particles. Two protons that were lost by the uranium atom are present in the alpha particle. Additionally, the two protons have a +2 charge. The particle's mass, or the sum of its protons and neutrons, is represented by the top number, 4, in this case. Alpha particles must also have two neutrons because they have two protons, making a total of four protons and neutrons. Two protons and two neutrons are the constant components of alpha particles.

A nuclear process known as "alpha decay" releases a particle made up of two protons and two neutrons when an unstable nucleus transforms to another element. The helium nucleus that is being ejected is known as an alpha particle.

Answer:

The appropriate alternative is option C "[tex]5.09\times 10^{14} \ s[/tex]".

Explanation:

The given value is:

Energy of photon,

E = [tex]3.37\times 10^{-19} \ J[/tex]

As we know,

h = [tex]6.626\times 10^{-34} \ Js[/tex]

Now,

The frequency of the light will be:

⇒  [tex]E=hv[/tex]

On substituting the given values, we get

⇒  [tex]3.37\times 10^{-19}=6.626\times 10^{-34}\times v[/tex]

On solving, we get

⇒                    [tex]v=5.09\times 10^{14} \ s[/tex]

If the energy of a photon of light is 3.37 x 10⁻¹⁹ J, then the frequency of the light is 5.09 x 10¹⁴ per sec.

Frequency of light will be calculated by using the below formula:
E = hυ, where

E = energy of photon = 3.37 x 10⁻¹⁹ J

h = plank's constant = 6.626 × 10⁻³⁴ Js

Putting these values on the above equation and calculate for the frequency as:

υ = 3.37 x 10⁻¹⁹ J / 6.626 × 10⁻³⁴ Js = 5.09 x 10¹⁴ per sec

Hence, option (C) is correct i.e. 5.09 x 10¹⁴ per sec.
