A face-centered-cubic cell contains 4 atoms, so the volume per atom is ...

  (389.80×10^-12 m)³/(4 atoms) ≈ 1.4725×10^-29 m³

Then the mass of 1 atom is ...

  (12020 kg/m³)(1.4725×10^-29 m³) ≈ 1.76995×10^-25 kg

Answer:

[tex]\boxed {\boxed {\sf \rho= 0.1 \ g/cm^3 }}[/tex]

Explanation:

Density is found by dividing the mass by the volume.

[tex]\rho=\frac{m}{v}[/tex]

The mass is 50 grams, but we have to find the volume.

Assuming this is a solid rectangular object, we can use this formula for volume:

[tex]v=l*w*h[/tex]

The length is 25 centimeters, the width is 10 centimeters, and the height is 2 centimeters.

[tex]v= 25 \ cm * 10 \ cm * 2 \ cm[/tex]

[tex]v= 250 \ cm^2 * 2 \ cm[/tex]

[tex]v= 500 \ cm^3[/tex]

Now we know the mass and volume:

[tex]m= 50 \ g\\v= 500 \ cm^3[/tex]

Substitute the values into the formula.

[tex]\rho = \frac{50 \ g}{500 \ cm^3}[/tex]

[tex]\rho= 0.1 \ g/cm^3[/tex]

The density of the object is 0.1 grams per cubic centimeter.

Answer:

2679.5 seconds  or 2679.5 / 60 = 44.66 minutes to produce 2 dm3 of chlorine gas.

Explanation:

To solve this we must be knowing each and every concept related to current. Therefore, it will take 44.66 minutes to produce  2 dm³ of chlorine gas by passing 6A current through concentrated sodium chloride solution.

When an electrical current continually runs in a single direction, it is said to be in direct current. Rectifiers, batteries, generators using commutators, and fuel cells all generate direct current. A flashlight or an appliance powered by batteries, for instance, both use direct current.

Among the most crucial subjects addressed in physics is AC, DC current. A form of electrical current known as an alternating current, sometimes known as an AC current, is one in which the direction of electron flow changes periodically.

2679.5 / 60 = 44.66 minutes to produce 2 dm3 of chlorine gas by passing a 6A current through concentrated sodium chloride solution.

Therefore, it will take 44.66 minutes to produce  2 dm³ of chlorine gas by passing 6A current through concentrated sodium chloride solution.

Lakes dry up. Shortage of water. Decrease in humidity.

Answer:

1.023 J / g°C

Explanation:

Mass, m = 37.9 g

Temperature increase (change) = 25.0°C

Heat = 969 J

Specific heat capacity ,  c= ?

The relationship between these quantities is given by the equation;

H = mcΔT

c = H / mΔT

c = 969 / (37.9 * 25)

c = 969 / 947.5 = 1.023 J / g°C

Explanation:

Answer:

EF = CH₂

Explanation:

The empirical formula of any compound would be the most simplified and simple chemical formula of a compound. To get this number, we need to get the data of how many moles of each atom of the compoud we have.

Analyzing the data, we just know that an unknown compound undergoes a combustion reaction and produces CO₂ and H₂O. As the compound only have Carbon and hydrogen, it's pretty easy to get the moles of each atom.

To get the moles of CO₂, we need the molar mass of CO₂, which is 44 g/mol, then the moles:

nCO₂ = 2.28 / 44 = 0.0518 moles of CO₂.

Now that we have the moles of CO₂, we can get the moles of Carbon. Since 1 mole of CO₂ is made of 1 mole of Carbon and 2 moles of oxygen, this means that we have 0.0518 moles of C.

Applying the same thing with the water, we have:

nH₂O = 0.702 / 18 = 0.039 moles of water

And 1 mole of water is made of 1 mole of oxygen and two moles of hydrogens, then the moles of Hydrogen are 0.078 moles.

With these moles, we can now calculate the empirical formula.

C = 0.0518 / 0.0518 = 1

H = 0.078 / 0.0518 = 1.51 ≅ 2

Now these two numbers, give us the number of atoms, in the empirical formula so:

Of course there is no compound that have only those number of atom, but remember that this is the empirical formula, so, it's a simplified or reduced formula of the molecular formula, which means that the real or whole molecular formula could have more atoms of C and H, but to know this, we need the molar weight of this compound, and the problem does not give this data.

Answer:

1.evaperation

2.condenstation

3.precipatation

Explanation:

So I guess condenstation leads to precipatation-

Answer:

Evaporation is when water/liquids changes state from a liquid to a gas. Which eventually with enough water water vapor (which is what forms when water evaporates), it turns into clouds. But when the clouds get too heavy and full of water. Rain/precipitation falls from those clouds.

The mass of one metal atom is [tex]1.770\times 10^{-22}[/tex]grams.

The metal atom is palladium.

Explanation:

Given:

A face-centered unit cell.

The density of the unit cell is [tex]12020 kg/m^3[/tex].

The edge length of the unit cell 389.08 pm

To find:

The mass of one atom of the metal

Solution:

The density of the unit cell = d = [tex]12020 kg/m^3[/tex]

The edge length of the unit cell = a = 389.08 pm

[tex]1 pm = 10^{-12} m\\a=389.08 pm=389.08\times 10^{-12} m=3.8908\times 10^{-10}m[/tex]

Total number of atoms in F.C.C unit cell = z = 4

The atomic mass of the metal atom = M

The density of the unit cell is given by:

[tex]d=\frac{z\times M}{N_A\times a^3}\\12020 kg/m^3=\frac{4\times M}{6.022\times 10^{23}mol^{-1}\times (3.8908\times 10^{-10}m)^3}\\M=0.106586 kg/mol\\1 kg=1000 g\\M=0.106586 kg/mol=0.106586 \times 1000 g/mol\\M=106.586 g/mol[/tex]

The mass of one mole of metal atom = 106.586 g

The mass of 1 atom of metal :

[tex]=\frac{106.586 g}{6.022\times 10^{23}}\\=1.770\times 10^{-22} g[/tex]

The mass of one metal atom is [tex]1.770\times 10^{-22}[/tex] grams.

The atomic mass of the metal atom is 106.586 g/mol which is close to the atomic mass of the palladium. Hence, the metal atom is palladium.

Explanation:

The general chemical equation for the complete combustion (or burning) of some hydrocarbon fuel is, in words, as follows:

hydrocarbon fuel and oxygen gas react to produce carbon dioxide gas and water vapor,

or, using chemical notation,

[tex]\mathrm{C_xH_y} + z\mathrm{O_2} \rightarrow \mathit{x}\mathrm{CO_2} + \frac{\mathit{y}}{2}\mathrm{H_2O}[/tex]

where

[tex]z = x + \frac{y}{4}.[/tex]

Don't worry if that looks daunting. In our case, we are given the identity of the fuel (methane, or CH₄), so our equations will be straightforward.

In words: Methane gas and oxygen gas react to produce carbon dioxide gas and water vapor (or methane gas + oxygen gas → carbon dioxide gas and water vapor).

In chemical notation:
