What is an excothermic change?
An exothermic change is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature. This type of reaction gives off energy in the form of heat as the reactants are converted to products. Examples include combustion reactions and many types of oxidation reactions.
What is combusion?
Combustion is a chemical reaction between a fuel and an oxidizing agent, typically oxygen, resulting in the release of heat and the formation of products such as water and carbon dioxide. It is a form of exothermic oxidation reaction.
What does a combustion reaction produce?
Carbon dioxide
What properties are used to identify substances?
Chemical composition, chemical reactions, color, crystalline structure, melting point, boiling point, hardness, odor, magnetic properties, etc.
How many kilojole per hr in 62.7 kilomol per hr of natural gas?
Since both units are per hour, we can omit them, that leaves us with ? kJ / 62.7 kmol nat. gas. Natural gas is usually a combination of gases, primarily methane, with some parts ethane and propane, and trace amounts of heavier hydrocarbons, sulfur, and other compounds. You also need to specify which type of "energy" you are after. In chemical engineering, we use several different definitions. The one you are probably after is how much heat you would get if you burned the gas, its heat of combusion. So, assuming that natural gas is almost completely methane, and you want to know how much energy you get from burning it, you can find through a site like NIST Chemistry Webbook. In this case, we'll use (delta)Hc = -890.7 kJ/mole. Solve for: -890.7 kJ/mol * 62.7 kmol * 1000 mol/kmol = x kJ If you are instead looking for how much energy is contained in the gas, you can lookup methane's specific enthalpy. Be aware that this number changes with temperature, pressure and phase. Oh, and lastly -- the unit is kiloJoule. A jole is a different and very obscure unit.
What is the formula which is the combusion of magnesium?
2Mg + O2 --> 2MgO
What is the proper name for burning a substance with oxygen?
first one is combusion
Can co2 be produced by non-living things?
of course,combusion of non living things produce CO2.
After which inventor is the internal-combusion engine named?
"internal combustion" means just that. It isn't named after anyone in particular.
What is exhaust gases of vehicles?
The primary exhaust gasses of the internal combusion vehicle are carbon dioxide, carbon monoxide, and water vapor.
What is fuel injected?
A system of fuel delivery where a precise amount of atomized fuel is fed into each combusion chamber at a specific time.
How does combustion of fossil fuels influence ground level ozone?
Combusion of fuels produce hydrocarbons. These cause global warming and thus ozone depletion.
In a gasoline engine the area in the cylinder head where the air and fuel mixture is burned is call the?
the answer is b cylinder just took the test its not the combustion chamber
What are used to identify substances?
odour,melting/boling point,solubility in water,sooty or non- sooty flame on combusion,sodium fusion test,colour on adding KMnO4..
What has the author D K Clark written?
D. K. Clark has written: 'Fuel, its combustion and economy' -- subject(s): Fuel 'Fuel: it combusion and economy' -- subject(s): Fuel
How do you make carbon doixide?
Probably the simplest way would be a simple combusion reaction.Take:2CH2 + 3O2 -> 2CO2 + 2H2OAny combustion reaction follows the form:Combustant + Oxygen -> Carbon Dioxide and Water.
What type of engine is a Wankel engine?
The Wankel engine is a type of internal combusion engine that uses a unique design to convert pressure into a rotational motion. It was invented by a German, Frank Wankel, and was first patented in 1929.
