Why are combustion reactions useful to humans?
Combustion reactions are useful to humans because they provide heat energy for cooking, heating, and generating electricity. They also power vehicles and machinery by converting chemical energy into kinetic energy.
Explain why complete combustion is desirable?
The advantages of a complete combustion reaction are that they don't release as harmful toxic pollutants. In an incomplete combustion Carbon dioxide, carbon monoxide and carbon is released. A complete combustion only releases carbon dioxide.
If you say 'oxygen gas supports combustion' are you talking about a chemical or physical reaction?
Combustion is a hemical reaction.
What is the maximum amount of useful work that can be accomplished under standard conditions by this reaction when 6 mol of C2H2 is burned?
To determine the maximum useful work from the combustion of 6 mol of C2H2 (acetylene), one must first consider the standard enthalpy change of the reaction. The combustion of 1 mole of C2H2 releases about -1300 kJ of energy. Therefore, for 6 moles, the total energy released is approximately -7800 kJ. Under ideal conditions, this energy can be converted to useful work, subject to efficiency losses, with the maximum work being close to 7800 kJ, assuming complete conversion and no energy losses.
How chemical change is useful to people?
Chemical change is useful because when it occurs, some desirable outcomes such as combustion occurs. Some reactions give off heat energy. Heat packs work by allowing certain chemicals to mix and give off heat.
Why are combustion reactions useful to humans?
Combustion reactions are useful to humans because they provide heat energy for cooking, heating, and generating electricity. They also power vehicles and machinery by converting chemical energy into kinetic energy.
Where is it useful for gases to be compressed?
Refrigerators, combustion engines, air cannons, SCUBA and submarines.
Does chlorine support combustion?
Chlorine gas supports the vigorous combustion of many elements to form their chlorides. For example, Sulphur and Phosphorus burn in the gas.
Why is coal combustion useful?
Coal combustion is useful because it generates electricity and heat, which are essential for industrial processes, residential heating, and power generation. It is a reliable and cost-effective energy source, particularly in countries with abundant coal reserves. However, coal combustion also releases pollutants and greenhouse gases, contributing to environmental and health issues.
Why is oxygen useful and how?
O is the gas that animals respirate. Also essential for combustion. It is a main component in organic matter.
How much useful energy does a gas boiler waste?
Probably about 25 percent of the heat of combustion goes up the stack
What are the uses of combustion?
a combustion engine perhaps?
What kind of energy isn't useful?
Virtually all forms and types of energy are useful in some way or another.
Petrol used in a car harmful or useful?
petrol is the same as gas for one. and two because it has a low combustion point making it easier to ignite. petrol is the same as gas for one. and two because it has a low combustion point making it easier to ignite.
Does water affect the heat of combustion of ethanol?
There are two angles to this question: 1. If your ethanol is contaminated with water it will reduced the amount of useful heat generated since the water will boil off while the ethanol is burning. 2. The water generated as a result of combustion is included as a term in the calculation of heat of combustion.
What are some small explosions that have useful purposes that the average person doesnt realize are explosions?
The power strokes occurring inside the cylinders of internal combustion engines.
Petrol is useed in a car engine-useful or harmful?
petrol is the same as gas for one. and two because it has a low combustion point making it easier to ignite. petrol is the same as gas for one. and two because it has a low combustion point making it easier to ignite.
