When might a galaxy appear redshifted and why?

1 answer:

6 0

Redshift is said to be experienced when the light or any other electromagnetic radiations from an object undergo an increase in the wavelength but it does not mean that the light literally becomes red.

Redshift occurs due to the expansion of space. It means the farther away the galaxy is from us, the more space it has expanded in the time.

Because as the light left the galaxy, more of the light has been stretched and so more redshifted the light is.

Barrier island refers to the large sandbars along the coastline that form

from deposition of sand over long period of time.

<h3>Features of a Sandy environment </h3>

The features of a sandy environment include the following:

Spits

Barrier islands

Tombolos

Barrier Island are formed when sand is deposited over a long time and this

helps to prevent erosion along the coastline area.

a compound is found to contain 31.1% sulfur and 68.9% chlorine determine the empirical formula for the sulfur and chlorine sampl

ollegr [7]

Answer:

Empirical formula = S₁Cl₂ = SCl₂

Explanation:

The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound.

This compound contains 31.1% sulfur and 68.9% chlorine.

That is 100g of the compound contains 31.1 g of sulfur and 68.9 g of chlorine.

Convert the mass of each element to moles using the molar mass from the periodic table.

Moles of Sulfur = $\frac{31.1}{32.065 } \\$

= 0.9699

Moles of Chlorine= $\frac{68.9}{35.453 } \\$

= 1.9434

Divide each mole value by the smallest number of moles calculated.

Units of sulfur = $\frac{0.9699}{0.9699} \\$

= 1

Units of Chlorine = $\frac{1.9434}{0.9699} \\$

= 2

Empirical formula = S₁Cl₂ = SCl₂
