Which best describes what is occurring when a door is almost closed and rays of light fan out from the small opening? absorption interference refraction diffraction

Answers

Answer 1

Answer:

The correct answer is Option D (diffraction).

Explanation:

Diffraction has been known as a mechanism through which light rays divide across clusters of darkness and light rather than into the colors of the rainbow. That is the twisting of such an obstacle across the sun. In this case, the challenge has been the door from which the illumination moves and bends.

Other alternatives are not relevant to the specified case. So, the alternative above would be appropriate.

Rahul was given iron filings and sulphur powder. He prepared a compound of iron sulphide by heating the components in a china dish. What would be his observation if he adds a few drops of dilute sulphuric acid into the compound?

Answers

Answer:

A gas with a rotten egg smell is evolved

Explanation:

When iron fillings and sulphur were heated in the vessel, the following chemical reaction took place;

Fe(s) + S(s) -----> FeS(s)

This is a direct combination reaction.

Subsequently, when dilute H2SO4 is added, the following reaction takes place;

FeS(s) + H2SO4(aq) ------> FeSO4(aq) + H2S(g)

He immediately observes the evolution of a gas with a rotten egg smell.

A teacher performs a flame test lab experiment for various compounds. During the lab, the teacher mislabels one of the solutions. She needs to identify the unknown sample. Explain how the teacher can identify the unknown sample.

Answers

Answer: By performing the flame test

Explanation:

The flame test can be performed by the teacher to visually identify the substance in the solution. The metals give a characteristic color on burning. The heat of the flame causes the excitation of the electrons present in the metal ions this leads to release of energy along with the emission of visible wavelength of light. This visible light can be observed by human eye. For example, the copper produces the blue color in flame, barium gives green flame, and sodium gives yellow flame.

What are glasses ?

Glasses are visual eyewear that have lenses fixed in a frame that holds them in front of a person's eyes. The frame often has a bridge over the nose and arms that rest over the ears. Glasses are also known as eyeglasses or spectacles.

The term "glasses" likely originated from the word "spyglass," which was originally used to describe "a pair of eyeglasses" that had to be held up to the eyes in order to be fully effective.

Eyeglasses, often known as glasses or spectacles, are lenses that are mounted in frames and worn in front of the eyes to improve vision or to correct astigmatism, myopia, or hyperopia.

Thus,  Josh could dry them with a towel to keep the glasses from being slippery.

Complete and balance each of the following equations for gas evolution reactions HCl(aq)+ZnS(s)>

Answers

2HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)

Further explanation  

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

Reaction

HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)

1. give equation

aHCl(aq) + bZnS(s) ⇒ ZnCl₂(aq) + cH₂S(g)

2. make an equation

H, left=a, right=2c⇒a=2c(eq 1)

Cl, left=a, right=2⇒a=2⇒c=1(from eq 1)

Zn, left=b, right=1⇒b=1

So the equation :

2HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)
