Sulfur dioxide is a main component of: photochemical smog, thermal inversion, industrial smog.

Answers

Answer 1

Answer:

Answer: industrial smog.

Explanation:

The industrial smog typically exists in the urban industrial areas where the large scale burning of the fossil fuels may lead to generation of huge amount of smoke and sulfur dioxide gas liberated into the atmosphere. These gaseous products gets mixed with the droplets of fog already present in the atmosphere. This lead to the formation of industrial smog. The industrial smog forms a thick blanket of smog or haze nearly close to the ground.

Answer 2

Answer:

Final answer:

Sulfur dioxide is a primary component of industrial smog and photochemical smog, but it does not directly influence thermal inversion. It is released into the atmosphere predominantly from burning fossil fuels.

Explanation:

Sulfur dioxide is a significant component in the creation of both industrial smog and photochemical smog, two serious urban air pollutants. During industrial activities, fossil fuels such as coal and oil that contain sulfur are burned, releasing sulfur dioxide into the atmosphere. This gas then reacts with water vapor and other compounds to form industrial smog. In the case of photochemical smog, when sulfur dioxide interacts with sunlight, volatile organic compounds, and nitrogen oxides, it contributes to the formation of this harmful type of smog. However, sulfur dioxide does not directly relate to the occurrence of thermal inversion, a weather-related phenomenon that can trap smog and other pollutants close to the ground.

Which compound has both ionic and covalent bonding?(1) CaCO3 (3) CH3OH
(2) CH2Cl2 (4) C6H12O6

Answers

The compound that has both ionic and covalent bonding is $\boxed{\left( 1 \right){\text{ CaC}}{{\text{O}}_3}}$ .

Further Explanation:

The attraction between different atoms, molecules and ions is known as a chemical bond. The formation of various types of compounds takes place as a result of these chemical bonds.

An ionic bond is formed as a result of the interaction between a metal and a non-metal. Metals have the tendency to lose electrons while non-metals tend to gain electrons. Due to this, metal atoms form cations by loss of electrons and non-metals become anions with the gain of electrons.

A covalent bond is formed by the mutual sharing of electrons between the bonded atoms. It is also called the molecular bond. Such bonds usually exist between two or more non-metals.

(1) ${\text{CaC}}{{\text{O}}_{\text{3}}}$

Its constituents are ${\text{C}}{{\text{a}}^(2 + )}$ and ${\text{CO}}_3^(2 - )$ ions. The bond between calcium and carbonate ions is an ionic bond. But the bond between the carbon atom and the oxygen atom of carbonate is formed by sharing of electrons so it is a covalent bond. So ${\text{CaC}}{{\text{O}}_{\text{3}}}$ has both ionic and covalent bonding and therefore this option is correct.

(2) ${\text{C}}{{\text{H}}_2}{\text{C}}{{\text{l}}_2}$

It has carbon, hydrogen and chlorine atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So ${\text{C}}{{\text{H}}_2}{\text{C}}{{\text{l}}_2}$ has only covalent bonds and therefore this option is incorrect.

(3) ${\text{C}}{{\text{H}}_3}{\text{OH}}$

It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So ${\text{C}}{{\text{H}}_3}{\text{OH}}$ has only covalent bonds and therefore this option is incorrect.

(4) ${{\text{C}}_{\text{6}}}{{\text{H}}_{{\text{12}}}}{{\text{O}}_{\text{6}}}$

It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So ${{\text{C}}_{\text{6}}}{{\text{H}}_{{\text{12}}}}{{\text{O}}_{\text{6}}}$ has only covalent bonds and therefore this option is incorrect.

Subject: Chemistry

Chapter: Ionic and covalent compounds

Keywords: chemical bond, ionic bond, covalent bond, CaCO3, CH2Cl2, C2H12O6, CH3OH, carbon, hydrogen, oxygen.

CaCO3 is the substance that contains both ionic and covalent bonds. Calcium ions (Ca2+) and carbonate ions (CO3-2) make up the salt known as CaCO3. Ionic bonds, which are created when one atom donates electrons to another atom, are what bind the calcium and carbonate ions together.

Three oxygen atoms and one carbon atom, linked together by covalent bonds, make up the carbonate ion. The three oxygen atoms and the carbon atom share electrons to create a covalent connection. Atoms exchange electrons to make covalent connections, whereas atoms give away electrons to produce ionic bonds.

In CaCO3, an ionic connection is created when the calcium atom donates electrons to the carbonate ion. The carbon atom shares electrons at the same moment.

Calculate the value of ?E in joules for a system that loses 115 J of heat and has 150 J of work performed on it by the surroundings.

Answers

Hey there!:

E = energy gained (input) - energy lost (output)

∆E = 150J - 115 J

∆E = 35 J

Hope that helps!

Final answer:

The change in internal energy (?E) of the system is 35 J based on the first law of thermodynamics.

Explanation:

This problem can be solved using the first law of thermodynamics, which states that the change in internal energy (?E) of a system is equal to the heat added to it (Q) minus the work done by it (W) - this is expressed as ?E = Q - W.

In this particular case, the system loses 115 J of heat, so Q equals -115 J (as it's lost, it's negative), and 150J work is performed on the system which equals +150 J (as work is done on it, it is positive). Therefore, substituting these values into the formula, we get: ?E = -115 J - (-150 J) = 35 J:

So, the change in internal energy of the system is 35 J.
