Given in the QUESTION :-⇒

Molar MASS of NITROBENZENE =123

Here 12.3 nitrobenezene Mole= 6×12.3 / 123

= 0.6 

CHARGE = 0.6 × 96500 

=57900

As 50% efficiency 

So, 2 × 57900

=115800 C .

Answer:

The CONDUCTIVITY of semiconductors may easily be modified by INTRODUCING impurities into their crystal lattice. The process of adding controlled impurities to a semiconductor is known as doping. The AMOUNT of impurity, or dopant, added to an intrinsic (pure) semiconductor varies its level of conductivity.

A combination reaction is a reaction in which two reactants COMBINE to form one product

Combination reactions are of three types

Similarly, non-metals MAY react with HIGHLY active metals to form covalent compounds. Example, sulphur reacts with oxygen gas to form gaseous sulphur dioxide

Reaction between two or more ELEMENTS:An example of this type of combination reaction is the reaction between a metal and a non- metal. Most metals react with non-metals to form ionic compounds. A good example of this would be:

Reaction between elements and compounds: An element and a compound react to form another compound. Example, carbon monoxide reacts with oxygen gas to form carbon dioxide.

Reaction between two compounds: Two compounds react with each other to form a new compound. Example, calcium oxide (quick LIME) reacts with carbon dioxide gas to form calcium carbonate (lime stone).

Explanation:

Acid rain is a rain or any other FORM of precipitation that is unusually acidic, meaning that it has elevated levels of HYDROGEN ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen OXIDE, which react with the water molecules in the atmosphere to produce acids. Some governments have made efforts since the 1970s to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes, and sulfur dioxide is produced by volcanic ERUPTIONS. Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing insect and aquatic life-forms, causing paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health.

Explanation:

2Cu + O₂ -> 2CuO

ANSWER:

answer (A) is a WRITE ANSWERS in this QUESTION

Answer:

Here is your explanation

Explanation:

MAINLY exchange of ION take place in positively ions likely metals. Highly charged ion replaces less charged ion for EG:-

CuSO4 + Na - - - - - > NaSO4 + Cu

Copper Sulphate + sodium - - - - - -> sodium Sulphate + copper

Here,

Highly reactively ELEMENT is sodium which replaces less reactive element which is copper.

This reaction shows change of ions

Change of ions occur in EVERY reaction.

Explanation:

The 4rth state of MATTER :plasma.

Natural applications:

1. Used as a starter of nuclear reaction inside the sun.

2. May also be produced inside earth. If it does, it is responsible for FORMING magnetic FIELD which protects earth.

Artificial uses:

NONE.

Because of its extremely high temperature, plasma is very difficult to store, because everything would melt when it would come in contact with the surface. Efforts are now being MADE to contain plasma in a "container" made by a field of million volts.

5th state of matter: Einstein-Bose condensate.

Natural uses:None. It is naturally impossible to reach absolute zero temperature.

Artificial uses: Till date, none. 5th state is only theoretically known. Till now, it has not been achieved.

Answer:

Explanation:

We store copper sulphate SOLUTION in a silver vessel because silver is less REACTIVE than copper.

So no displacement REACTION OCCURS.

Silver nitrate solution is not STORED in copper vessel because copper is more reactive than silver

ANSWER:

AgCl + 2NH4OH → [AG(NH3)2]Cl + 2H2O

Explanation:

NOTE. This is "silver diammine" and not "silver diamine". There are two of the letter "m". "Amine" refers to the -NH2 group. If it contains ammonia, then "ammine" has two m's.

Silver Ammonium Chloride. This is a complex compound and considered not to be a TRUE salt.

Silver chloride react with ammonium hydroxide to produce diamminesilver chloride and water. Silver chloride - SOLID. Ammonium hydroxide - concentrated SOLUTION.

A neutralization reaction is when an acid and a BASE react to form water and a salt and involves the combination of H+ IONS and OH- ions to generate water. ... When a solution is NEUTRALIZED, it MEANS that salts are formed from EQUAL weights of acid and base.

Answer:

Lithium.

Explanation:

LI is the smallest of these ELEMENTS REGARDLESS of the CHARGE on the respective ions. This is because Li is in 2nd PERIOD and all the others are in 3rd period.

Answer:

Explanation:

Zn + HCL = H2 + ZnCl2

It is a single displacement reaction where -

Zinc is oxidised (it becomes positive) and water is neutralized. It is a reduction-oxidation reaction where one of the REACTANTS loses oxygen and the other one gains.

So, answering your question, we get hydrogen GAS and a salt.

Hydrogen gas, is identified by EXPOSING it to a burning flame. It explodes (a bit,) with a pop sound. This is because Hydrogen is HIGHLY explosive.

Answer:

Energy Transformations

An energy transformation is the change of energy from one form to ANOTHER. Energy transformations occur everywhere every SECOND of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical. Because the law of CONSERVATION of energy states that energy is always conserved in the UNIVERSE and simply changes from one form to another, many energy transformations are TAKING place constantly.

Examples of Energy Transformations:

1. A toaster transforms electrical energy into thermal energy.

2. A blender transforms electrical energy into mechanical energy.

3. The sun transforms nuclear energy into ultraviolet, infrared, and gamma energy all forms of electromagnetic energy.

4. Our bodies convert chemical energy from food into mechanical and electrical energy to allow us to move.

5. A natural gas stove converts chemical energy from burning into thermal energy used to cook food.

EXPLANATION:

(1)This PHENOMENON is called evaporation.

(2)The liquid takes HEAT from its surroundings (this results in the increase in temperature of the liquid ). This heat is used by the liquid to increase the  kinetic energy between the particles (as kinetic energy increases with an increase in temperature). Now, as we know that the kinetic energy is highest in gases, the increase in kinetic energy results in the conversion of the liquid into GAS.

(3)The three factors are - surface area, humidity, wind speed.
