The radius of a tungsten atom is 137 pm. how many tungsten atoms would have to be laid side by side to span a distance of 3.51 mm?

Answers

Answer 1

2.5 × 10⁻⁷ atoms will occupy 3.51 mm.

Firstly converting the radius of a tungsten atom from picometer to millimeter.

As per the known fact, 1 pm = 10⁻⁹ mm

Radius in mm = 137 × 10⁻⁹ mm

Radius in mm = 1.37 × 10⁻⁷ mm  

Now, if atoms are laid side by side, then the distance occupied by each atom will be equal to it's diameter.

Now, 1.37 × 10⁻⁷ mm space is occupied by : 1 atom

Space occupied by 3.51 mm = (1÷ 1.37 × 10⁻⁷)×3.51

Performing multiplication and division

Space occupied by 3.51 mm = 2.5× 10⁻⁷ atoms

Hence, 2.5× 10⁻⁷ atoms will occupy 3.51 mm.

Explanation:

A cube 5.0 cmcm on each side is made of a metal alloy. after you drill a cylindrical hole 2.5 cmcm in diameter all the way through and perpendicular to one face, you find that the cube weighs 6.30 nn.

Answers

(a) The density of the metal is 7486.88kg/[tex]m^{3}[/tex]

(b)  The cube weigh 9.17N before we drill a hole in it.

The Newton's second rule, the definition of density, and the geometric relationships that enable us to calculate the volume of the given figures must all be applied in order to answer this problem.

The volume of a cube with equal sides is found in this situation by

[tex]V_{c} = l^{3}[/tex]

[tex]V_{c} = 5^{3}[/tex] = 125[tex]cm^{3}[/tex]

When it comes to perforated material, we know that its volume is determined by the cylindrical geometry, or

[tex]V_{d} = \pi r^{2} l[/tex]

[tex]V_{d} = \pi (\frac{2.5}{2}) ^{2} *5[/tex] = 12.5[tex]\pi cm^{3}[/tex]

The net volume would be in this case: ΔV = 125[tex]cm^{3}[/tex] - 12.5[tex]\pi cm^{3}[/tex] = 85.75[tex]cm^{3}[/tex] = 85.75×[tex]10^{-6}[/tex][tex]m^{3}[/tex]

Since we already know the weight and gravity, we can use Newton's second law to get the mass,

F = mg

[tex]m =\frac{6.3}{9.8}[/tex]

m = 0.642kg

Part(a) Based on the relationship between density and the mass and volume units, we must use;

ρ = m/v

ρ = [tex]\frac{0.642}{85.75*10^{-6} }[/tex]

ρ = 7486.88kg/[tex]m^{3}[/tex]

So, the density of the metal is 7486.88kg/[tex]m^{3}[/tex]

Part(b) Next, determine the cube's weight.

W = mg = Vρg

W = 125×[tex]10^{-6}[/tex] × 7486.88 × 9.8

W = 9.17N

The cube weigh 9.17N before we drill a hole in it.

Rolls of aluminu are 304 mm wide and 0.016mm thick. what maximum length of aluminum foil (in m) can be made from 1.10kg of aluminum? density of al 2.70g/cm'

Answers

Aluminum foil can be made to a maximum length of 87.76 meters from 1.10 kg of aluminum.

How do you compute density?

Density is defined as d = M/V, where d is density, M is mass, and V is volume.Though the SI unit of density is kg/m3, we use g/cm3 for solids, g/ml for liquids, and g/L for gases for convenience.Density is an important concept because it tells us which substances will float and which will sink when placed in a liquid. Substances float in general if their density is less than the density of the liquid in which they are placed.

By using the above formula for density

ρ = mass / volume

⇒ As given in the problem Rolls of aluminum foil are 304 mm wide and 0.016-mm thick.

the mass of the aluminum = 1.10-kg

mass = 1100 grams

the density of the aluminum = 2.70 g/cm3

density = 17/3

⇒ 2.70 g/cm3 = 1100 grams /volume

volume = 1100/ 2.70

            =407.40 cm3

volume = width ×thickness ×length

407.40 cm3 = 30.4 ×.0016 ×length

⇒ length = 8375.97 cm

              = 87.76 meters

Thus, the maximum length of aluminum foil that can be made from 1.10-kg of aluminum would be 87.76 meters.

What volume, in ml, of 6.0 m sodium hydroxide is required to fully react with the copper (ii) nitrate produced?

The question is incomplete as the mass of copper is also needed to solve this. The given mass of copper is 0.9075 g.

The volume of 6.0 M sodium hydroxide(NaOH) required to fully react with copper nitrate produced is 4.76 ml.

The reaction between copper(Cu) and nitric acid(HNO3) is as follows:

Cu + HNO3 = Cu(NO3)2

According to the above reaction

1 mole of copper produces 1 mole of copper nitrate

Or 63.5 g of copper produces 1 mole of copper nitrate

Thus, 0.9075 g of copper produces 1/63.5 x 0.9075 = 0.0143 moles of copper nitrate

The reaction between sodium hydroxide(NaOH) and copper nitrate {Cu(NO3)2} is as follows:

2NaOH + Cu(NO₃)₂ ---> 2NaNO₃ + Cu(OH)₂

From the above equation,

1 mole of copper nitrate fully reacts with 2 moles of sodium hydroxide

Thus, 0.143 moles of copper nitrate fully reacts with 2 x 0.143 = 0.286 moles of sodium hydroxide

The molarity of the given  NaOH solution is 6 M.

Hence its volume would be

Molarity = No. Of moles/Volume of solution(in liters)

6 = 0.286/ Volume

Volume = 0.0476 liters or 47.6 ml.

Hence, the volume of 6.0 M sodium hydroxide(NaOH) required to fully react with the copper nitrate produced is 4.76 ml.

Sound from the siren of an emergency vehicle has a frequency of 667.2 hz and moves with a velocity of 349.8 m/s, thus the distance from one condensation to the next is 0.52m.

Waves of sound exist. A disturbance of matter that is conveyed from its source outward is how sound is more precisely defined. Anything that is shifted out of its balance is considered a disturbance.

Some sound waves are classified as periodic waves, which means that the matter’s atoms move in a straightforward harmonic fashion.

Pressures are a little bit higher and lower as a result. Low pressure regions are rarefactions, and higher-pressure regions are compressions. The air is moved by the pressure anomaly.

The thickness of an anti-reflective coating is 96 nm.

Define Wavelength?

The wavelength in waves is defined as the distance between the crests and troughs. It can be calculated in the meter in the SI system. The crest is the upper part of the wave, and the trough is the lower part.

Given that,

The index of the anti-reflective coating is n = 1.3

The wavelength is denoted as  λ = 500 nm = 500×[tex]10^{-9}[/tex]m

The expression for interference can be written as

2t = (m+½)λf

m=0 is the minimum reflection order.

λf is referred to as the wavelength of the film.

By substituting the values in the above expression we get,

2t = (m+½)λf

2t = (0+½)λf

t = λf/4 (this will noted as equation 1 for more clarity )

The wavelength of the light in a medium with refractive index can be expressed as

λf = λ/n

By substituting the values in equation1 we get,

t = λf/4

t = (λ/n)/4

t = λ/4n = 500/(4×1.3) = 96 nm.

Kilopascal (kPa), a 1,000-fold increase in the meter-kilogram-second system’s measure of pressure and tension (the International System of Units [SI]).

Blaise Pascal, a French mathematician and scientist, is honored by its name.

How is kPa determined?

The formula below can be used to translate kg/cm2 into kPa:

A kPa equals 1000 pascals (Pa)

1 kg/cm2 is equal to 98066.5 pascals (Pa), or kPa value multiplied by 1000 Pa.

Thereafter,

T = 26°C

= 299K

P = 100kPa

P= 100/101.325

=0.986923 atm

mass = 3.25g

Atomic mas of H = 1.00784

molar mass of H2 gas = 2x10.00784

= 2.01568g/mol

mole of H2 in 3.25g = 3.25/2.01568 = 1.612359 mol

This gas provided in the question follows the ideal gas equation, so it can be written as

PV = nRT

⇒ V = nRT/P

= (1.612359x 0.0821x 299) / 0.986929

⇒ V = 40.104473

V = 40.1 L

Density = mass / volume

Thus, mass = density * volume

150.0mL H2O * (1.000 g/mL) = 150.0 g H2O.

Now simply add the two masses: 150g + 4.436g = 154.436g

Q = mcdT

Q = heat added or removed

m = mass of substance = 154.436g

c = specific heat of this solution is 4.06j/g C

dT = change in temperature

Q = 154.436g * 4.06 * 11.5

Q =7,210.62J

Q = 7.21kj

In the classical view of the atom, Bohr pictured electrons orbiting the positively charged nucleus similar to how the planets orbit the Sun. While this picture was not entirely correct, it provides a good framework in which to make calculations about the energies of electrons. Different from the predictions of Newtonian mechanics, which allows any energy to be possible, Bohr described the electron orbits (now called orbitals) as having specific energies. Rank the following electron energy states according to their electron energies. Rank from highest to lowest energies. I need help with this question please, my exam is tomorrow.
