If Earth is in between the sun and the Moon in both Image 1 and Image 2, why do you think a lunar eclipse is only happening in Image 2?

Answer:

required diameter is 7.65 mm

Explanation:

Given the data in the question;

F = 6660 N

l₀ = 380 mm = 0.38 m

E = 110 GPa = 110 × 10⁹ N/m²

Δl = 0.50 mm = 0.0005 m

So, lets assume the deformation is elastic;

d₀ = √(  [4l₀F] / [πEΔl] )

we substitute

d₀ = √(  [4 × 0.38 × 6660] / [π × (110 × 10⁹) × 0.0005]] )

d₀ = √( 10123.2 / 172787595.947 )

d₀ = √( 5.85875 × 10⁻⁵ )

d₀ = 0.007654 m

d₀ = ( 0.007654 × 1000 )mm

d₀ = 7.65 mm

Therefore, required diameter is 7.65 mm

Molecular geometry of o3

Ozone has three electron groups around the central oxygen, so has the trigonal planar electron geometry. The molecular geometry is bent: The Effect of Lone Pairs (contd.) With four electron groups (tetrahedral electron geometry), there can be one or two lone pairs around the central atom.

Explanation:

a)

[tex]k _{sp} = [Ag {}^{ + } ][Cl {}^{ - } ] \\ but \: [Ag {}^{ + } ] = [Cl {}^{ - } ] \\ k _{sp} = [Ag {}^{ + } ] {}^{2} \\ [Ag {}^{ + } ] = \sqrt{k _{sp}} \\ = \sqrt{1.8 \times {10}^{ - 10} } \\ = 1.34 \times {10}^{ - 5} mol {dm}^{ - 3} [/tex]

b)

It has not reached equilibrium because the silver concentration is not yet equal to the value of Ksp.

Answer:

4 electrons/atom

Explanation:

The conductivity of the lead σ = neμ where n = electron density, e = electron charge = 1.602 × 10⁻¹⁹ C and μ =  electron mobility of lead = 2.3 cm²/(V·s) = 2.3 × 10⁻⁴ m²/(V.s)

Making n subject of the formula, we have

n = σ/eμ

Since σ = 4.90 × 10⁶ (Ω·m)⁻¹

Substituting the values of the variables into the equation, we have

n = σ/eμ

n = 4.90 × 10⁶ (Ω·m)⁻¹/(1.602 × 10⁻¹⁹ C × 2.3 × 10⁻⁴ m²/(V.s))

n = 4.90 × 10⁶ (Ω·m)⁻¹/(3.6846 × 10⁻²³ Cm²/(V.s))

n = 1.33 × 10²⁹ electrons/m³

We now find the number of moles of lead present in 1 m³ of lead.

So n' = ρ/M where ρ = density of lead = 11.4 g/cm³ = 11.4 g/cm³ × 10⁶ cm³/m³ = 11.4 × 10⁶ g/m³ and M = atomic weight of lead = 207 g/mol

So, n' = ρ/M

N = 11.4 × 10⁶ g/m³/207 g/mol

n' = 0.0551 × 10⁶ mol/m³

n' = 5.51 × 10⁴ mol/m³

Since n' = N/N' where N = number of atoms of lead in 1 m³ of lead and N = Avogadro's constant = 6.022 × 10²³ mol⁻¹

N = n'N' = 5.51 × 10⁴ mol/m³ × 6.022 × 10²³ mol⁻¹

N = 33.18 × 10²⁷ atoms/m³

N = 3.318 × 10²⁸ atoms/m³

So, the number of electron per atom is N" = n/N

= 1.33 × 10²⁹ electrons/m³ ÷ 3.318 × 10²⁸ atoms/m³

= 0.4 × 10¹ electrons/atom

= 4 electrons/atom

Answer:

Electrons in sigma bonds remain localized between two atoms. Sigma bond results from the formation of a molecular orbital by the end to end overlap of atomic orbitals. Electrons in pi bonds can become delocalized between more than two atoms. Pi bonds result from the formation of molecular orbital by side to side overlap of atomic orbitals.

Answer:

[tex]T_2=400.73K[/tex]

Explanation:

From the question we are told that:

Activation energy [tex]E_a= 51.02 kJ/mol.=>51.02*10^3J/mol[/tex]

Reaction Ratio [tex]\triangle K=4.50[/tex]

Initial Temperature [tex]T_1=365K[/tex]

Generally the equation for Final Temperature [tex]T_2[/tex] is mathematically given by

 [tex]log \triangle K=\frac{E_a}{2.303R}*(\frac{T_2-T_1}{T_1T_2})[/tex]

Where

 [tex]R=Gas constant[/tex]

 [tex]R =8.3143[/tex]

Therefore

 [tex]log 4.50=\frac{51.2*10^3}{2.303*8.31432}*(\frac{T_2-365}{365*T_2})[/tex]

 [tex]log 4.50=7.328*\frac{T_2-365}{T_2}[/tex]

 [tex]0.0892=\frac{T_2-365}{T_2}[/tex]

 [tex]0.0892T_2=T_2-365[/tex]

 [tex]365=T_2-0.0892T_2[/tex]

 [tex]365=0.91T_2[/tex]

 [tex]T_2=\frac{365}{0.91}[/tex]

 [tex]T_2=400.73K[/tex]

Answer:

A. Summers are mild to hot, B. Winters are cold.

V = 3.9 L

Explanation:

Given:

T = 23°C + 273 = 296K

n = 0.16 mol He

P = 101 kPa = 0.997 atm

R = universal gas constant = 0.08205 L-atm/mol-K

V = ?

Using the ideal gas law,

PV = nRT

V = nRT/P

= (0.16 mil He)(0.08205 L-atm/mol-K)(296K)/(0.997 atm)

= 3.9 L

Answer:

Amount of iron fillings in mixture = 60 mg

Explanation:

Given:

Total mass of mixture = 100 mg

Amount of salt in mixture = 10 mg

Amount of sand in mixture = 30 mg

Find:

Amount of iron fillings in mixture

Computation:

Using Law of Conservation of mass;

Total mass of mixture = Amount of salt in mixture + Amount of sand in mixture + Amount of iron fillings in mixture

100 = 10 + 30 + Amount of iron fillings in mixture

100 = 40 + Amount of iron fillings in mixture

Amount of iron fillings in mixture = 100 - 40

Amount of iron fillings in mixture = 60 mg
