Explain the three types of cumbusion ??​
Alik [6]

Answer:

Complete Combustion

One of the types of combustion is Complete Combustion. Complete combustion occurs in an unlimited supply of air, oxygen in particular. Also, complete combustion is also known as clean combustion. Here the hydrocarbon will burn out completely with the oxygen and leave only two byproducts, water, and carbon dioxide.

An example of this is when a candle burns. The heat from the wick will vaporize the wax which reacts with the oxygen in the air. The two products of the reaction are water and carbon dioxide. In an ideal situation all the wax burns up and complete combustion takes place

2] Incomplete Combustion

Incomplete combustion takes place when the air is in limited supply. And as opposed to complete combustion it is otherwise known as dirty combustion. Due to lack of oxygen, the fuel will not react completely. This, in turn, produces carbon monoxide and soot instead of carbon dioxide.

An example is burning of paper. It leaves behind ash (a form of soot) as a byproduct. In a complete combustion, the only products are water and carbon dioxide. Also, incomplete combustion produces less energy than complete combustion.

3] Rapid Combustion

Another type of combustion is Rapid Combustion. Rapid energy needs external heat energy for the reaction to occur. The combustion produces a large amount of heat and light energy and does so rapidly. The combustion will carry on as long as the fuel is available.

An example is when you light a candle. The heat energy is provided when we light the candle with a matchstick. And it will carry on till the wax burns out. Hence it is a rapid combustion

4] Spontaneous Combustion

As the name suggests the combustion occurs spontaneously. This means that it requires no external energy for the combustion to start. It happens due to self-heating. A substance with low-ignition temperatures gets heated and this heat is unable to escape.

The temperature rises above ignition point and in the presence of sufficient oxygen combustion will happen. The reaction of alkali metals with water is an example.

5] Explosive Combustion

Explosive Combustion happens when the reaction occurs very rapidly. The reaction occurs when something ignites to produce heat, light and sound energy, The simple way to describe is it to call it an explosion. Some classic examples are firecrackers or blowing up of dynamite.

Determine the direction that each of the reactions will progress. Assume that the reactants and products are present in equimola
xxMikexx [17]

Answer:

It would move either left or right

Explanation: Taking assumption that,

Fructose + ATP fructose - 6 - phosphate + ADP (The standard free energy of hydrolysis for fructose-6-phosphate is - 15.9 kJ/mol.) 3 - phosphoglycerate + ATP 1,3 - bisphosphoglycerate + ADP (The standard free energy of hydrolysis for 1,3-bisphosphoglycerate is - 4 9.3 kJ/mol.) pyruvate + ATP phosphoenolpyruvate + ADP (The standard free energy of hydrolysis for phosphoenolpyruvate -is -61.9 kJ/mol.)

What are the names of the following three compounds (see attached)
balu736 [363]

Answer:

1. 4-ethyl-1-heptene

2. 6-ethyl-2-octene

3. 1-butyne

Explanation:

The compounds are named according to IUPAC rules.

Compound 1:

  • Identify the longest carbon chain. This chain is called the parent chain.
  • Identify all of the substituents (groups appending from the parent chain).
  • The parent chain is numbered so that the multiple bonds have the lowest numbers (double has the priority over alkyl substituents).
  • The longest chain contains 7 carbon atoms, so taken the name hept.
  • The double bond between C1 and C2, so take no. 1 and add the suffix ene to hept "1-heptene".
  • The ethyl group is the alkyl substituent on position 4.
  • So the name is 4-ethyl-1-heptene.

Compound 2:

  • Identify the longest carbon chain. This chain is called the parent chain.
  • Identify all of the substituents (groups appending from the parent chain).
  • The parent chain is numbered so that the multiple bonds have the lowest numbers (double has the priority over alkyl substituents).
  • The longest chain contains 8 carbon atoms, so taken the name oct.
  • The double bond between C2 and C3, so take no. 2 and add the suffix ene to oct "2-octene".
  • The ethyl group is the alkyl substituent on position 6.
  • So the name is 6-ethyl-2-octene.

Compound 3:

  • Identify the longest carbon chain. This chain is called the parent chain.
  • Identify all of the substituents (groups appending from the parent chain), there is no substituents.
  • The parent chain is numbered so that the multiple bonds have the lowest numbers (Triple bond here take the lowest number).
  • The longest chain contains 4 carbon atoms, so taken the name but.
  • The triple bond between C1 and C2, so take no. 1 and add the suffix yne to but "1-butyne".
  • So the name is 1-butyne.
