Brainliest if correct

I believe that there is a spectrum of light in which we can see. When the white light enters the prism, it is refracted and bends into the visible light we can see of the spectrum.

The reason we always see the spectrum in the same order is because it is how our brain perceives it. Animals could see it in a different order, etc. This is just how the human brain sees it.

Light is distorted, or refracted, as it travels through a prism, by the angles and plane faces of the prism, and each wavelength is refracted by a significantly different number. As a result, all of the colors in the sun's white light split into the different color bands that make up a rainbow.

Which application of hydrates best relies on the anhydrous compound’s ability to both absorb water and retain water?

anzhelika [568]

Answer : Option A) Diaper.

The main component in manufacturing of diaper is natural fibre or man made fibre both mixed, which acts as an absorber and storer of water. There are also better variations available in market which induces the more absorption and storage of fluids by using certain hydrates along with the fibres.

In the reaction below, 22 g of H2S with excess

BartSMP [9]

Answer:

24%

Explanation:

From the question, the limiting reactant is H2S.

The reaction equation is;

2H2S + O2 → 2S + 2H2O

Number of moles of H2S reacted = 22g/34 g/mol = 0.647 moles

According to the reaction equation;

2 moles of H2S yields 2 moles of sulphur

0.647 moles of H2S yields 0.647 moles of sulphur

So;

Theoretical yield of sulphur = 0.647 moles * 32 g/mol = 20.7 g

Actual yield = 5 g

% yield = actual yield/theoretical yield * 100

% yield =5 g/20.7 g * 100

% yield = 24%

1. What is an isomer? How many possible isomers of hexane are there? What are the structural differences between these isomers?

UNO [17]

When two compounds have same molecular formula but different structural formula, they are said to be isomers of each other and this phenomenon is called as isomerism.

Hexane has six isomers.

The isomers of hexane have a difference in their structure due to parent chain length (chain isomerism). They are also differentiated on the basis of straight chain as in n-hexane and branched chain as in remaining five. Structures along with names are shown below.
