At sunset the light from the sun grazes across the surface of the earth, passing through a long column or pathlength of atmosphere. During its passage through the atmosphere the blue components of the light are reduced in intensity, making the transmitted beam of sunlight more yellow or even red in color.

hope this helps ^^

Answer:

Here ya go ;)

Small particles of dust and pollution in the air can contribute to (and sometimes even enhance) these colors, but the primary cause of a blue sky and orange/red sunsets or sunrises is scattering by the gas molecules that make up our atmosphere. ... In this way, clouds act as a screen on which nature's colors are painted.

Answer:

three chlorine atoms

Explanation:

We know, molecular mass of sucrose is 342 g/mol.

So, number of moles in 18 g is :

[tex]n_1 = \dfrac{342\ g/mol}{18\ g}\\\\n_1 = 0.053 \ moles[/tex]

Also, number of moles of water is :

[tex]n_2 = \dfrac{180}{18} \\\\n_2 = 10 \ moles[/tex]

We know, 1 mole of sucrose contain 11 moles of oxygen.

So,

[tex]n' = 0.053\times 11\\\\n'= 0.583\ moles[/tex]

1 mole of water contain 1 mole of oxygen .

So, moles of oxygen in water are :

[tex]n'' = 10\ moles[/tex]

Total number of moles, [tex]n' + n'' = 10.583 \ moles[/tex] .

Number of oxygen atoms are :

[tex]N = 6.022 \times 10^{23}\times 10.583\\\\N = 6.37 \times 10^{24}[/tex]

Hence, this is the required solution.

Single replacement/displacement

Given

Type involves free element

Required

Type of reaction

Solution

Single replacement/displacement occurs when a more active element replaces another less active element in the compound to form a new compound

The activity of this element can be seen from the voltaic series

Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au  

The more to the left, the element is more reactive (easily release electrons) and the stronger reducing agent  

The general formula for single replacement :

A + BC ⇒ AC + B

From this general formula shows that there are 2 free elements on both sides (reactants and products)

Answer:

When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot. To convert minutes to hours, the appropriate conversion value is 60 minutes equal 1 hour

Answer:

The balanced chemical reaction is written as follows:

bacl2 + na2so4 → baso4 + 2nacl

Therefore, the number of chlorine atoms in the reactants side and the products side would be 2 atoms in both sides which should be the case because the number of atoms in each side should have the same number.

The appearance of the three stars is compared by their colors and sizes.

In the image you can see the stars of the constellation Orion.

According to the above, it can be inferred that the three stars differ in their colors and sizes. Their colors can be determined by the chemical composition of them, while their sizes by the distance that separates them from the Earth, making the farthest ones look smaller and the closest ones, bigger.

Answer:

R = 40 ohms

Explanation:

Two bulbs have a resistance of 20 ohms when working normally.

When they are placed in series, the combined resistance is given by :

R = R₁ + R₂

We have, R₁ = R₂ = 20 ohms

R = 20 +20

= 40 ohms

Hence, the combined resistance of the two bulbs is 40 ohms.

Half-life = 28.8 years

Explanation:

The radioactive decay of an atom follows the equation:

Ln[A] = -kt + ln[A]₀

Where [A] is actual amount of isotope after time t; k is decay constant and [A]₀ initial amount of isotope

Solving for k:

Ln[0.393g] = -k*10yrs + ln[0.500]

-0.2408 = -k*10yrs

0.02408yrs⁻¹ = k

Half-life, is:

Half-life = ln 2 / k

Half-life = ln 2 / 0.02408yrs⁻¹

Half-life = 28.8 years

The isotope [tex]38Sr^{90}[/tex] is one of the extremely hazardous species in the residues from nuclear power generation. The strontium in a 0.500-g sample diminishes to 0.393 g in 10.0 yrs, the half-life is - 28.78

Formula:

radioactive decay follows first-order kinetics,  

k = [tex]\frac{1}{t}ln\frac{a}{x}[/tex]

Given:  

a = initial amount = 0.5 g  

x = amount of isomer after 10 years = 0.393 g  

t= time   = 10 years

Solution:  

k =  [tex]\frac{1}{10}ln\frac{0.5}{0.393}[/tex]

   = 0.02408  

k = [tex]\frac{0.693}{t/2}[/tex]  

T(1/2) = half-life time

= [tex]\frac{0.693}{k}[/tex]

=   [tex]\frac{0.693}{0.02408}[/tex]

= 28.78 years.

Thus, The isotope [tex]38Sr^{90}[/tex] is one of the extremely hazardous species in the residues from nuclear power generation. The strontium in a 0.500-g sample diminishes to 0.393 g in 10.0 yrs, the half-life is - 28.78
