Answer:

Natural chemicals:

1) Water: H₂O

2) Oxygen: O₂

3) Nitrogen: N₂

Artificial chemicals:

1) PVC, polyvinil chloride (a plastic used in toys and hoses, among others)

2) PE, polyethilene (a plastic used in containers, among others)

3) Baquelite (a plastic used in pan handles, among others)

Explanation:

1) All the substances are chemicals, since chemist is the science of the elements and compounds, their properties, compositions and transformations.

2) Natural chemicals are those that you find in nature: the plants, the air, the water sources, the soils, all have chemicals, which are considered natural.

The oceans have sodium chloride, iodine, and other salts.

The air has nitrogen, oxygen, carbon dioxide, argon, methane.

The solid part of the Earth has salts, elements and minerals: gold, carbon, aluminum, silicon, phosphorus, among many others.

The plants elaborate sugar (glucose), oxygen and water.

So, the nature is the biggest chemical laboratory. And all those are natural chemicals.

2) Artifical chemicals are those created by the man.

The man creates chemicals to imitate the nature, tho enhance it, for scientific reasons, or just for fun.

Some of the chemicals made by the man are equal to those in nature (or almost equal). Some are simply purification of chemicals made by the nature. Others are great creations, even some are results of the luck, others are authentical result of well aimed work.

Artificial flavors, artificial fabrics, a huge divertity of plastics, food, medicines, detergents, soap, among other petrochemicals, are some artificial chemicals.

Both natural and artificial chemicals may be benefitcal or harmful. It is the use, the doses, and the intentions what may do the difference between good and bad chemicals; not the origin.

Plastic sheet is transparent or translucent?
Karolina [17]

Answer:

Translucent

Explanation:

Transparent vs Translucent

Transparent: When light comes in contact with transparent materials, nearly all of it goes straight through it

Translucent: When light comes in contact with translucent materials, only some of it will go through it such as plastics or frosted glass.

What does the name iron(ii) in a compound indicate about the cation?
bija089 [108]

Answer:- Fe^+^2

Explanations:- Transition elements shows variable oxidation states. So, while naming these compounds we use the roman numerals to tell their oxidation states.

For example, if someone writes just Iron oxide then it would not be correct since Iron could be in +2 or +3 states. So, it might be Fe^+^2 or Fe^+^3 . So, the right was is to mention the oxidation state of the transition metal.

If the name is written as Iron(II) in a compound then it means there is +2 charge on iron and it is Fe^+^2.

The Balmer series consists of the spectral lines from hydrogen for an electron making a transition from an excited state to the
MaRussiya [10]

Answer:

Wavelength of the first four spectral line:

\lambda_1=1216{\AA}

\lambda_2=1026{\AA}

\lambda_3=972.8{\AA}

\lambda_4=950{\AA}

Explanation:

Lman series when electron from higher shell number and jumps to 1st shell then all the possible lines is called as lyman series.

to calculate wavelength of first four spectral line:

For hydrogen Z=1;

by using rydberg equation

\frac{1}{\lambda} =RZ^2[\frac{1}{n_1^2} -\frac{1}{n_2^2} ]

1. n=2 to n=1

\frac{1}{\lambda} =RZ^2[\frac{1}{n_1^2} -\frac{1}{n_2^2} ]

\frac{1}{R} =912{\AA} =rydberg constant

\lambda=\frac{4}{3R}

\lambda_1=1216{\AA}

2. n=3 to n=1

\lambda=\frac{9}{8R}

\lambda_2=1026{\AA}

3. n=4 to n=1

\lambda=\frac{16}{15R}

\lambda_3=972.8{\AA}

4. n=5 to n=1

\lambda=\frac{25}{24R}

\lambda_4=950{\AA}

Which substance is the oxidizing agent in this reaction? 2CuO+C→2Cu+CO2 Express your answer as a chemical formula.
Alja [10]
The oxidizing agent is the one that is reduced in the reaction. In this reaction, the charge of Cu falls from +2 to zero charge (neutral atom in the right side). Hence, CuO is the oxidizing agent. The reducing agent, the one being oxidized is carbon from zero charge to +4. The answer is CuO.
