What are the chemical reactions in internal combustion engine?
Internal combustion engines usually use some kind of hydrocarbon fuel (gasoline for example). The fuel is burned together with the oxidizer (atmospheric air in most cases with the exception of rocket engines). The result of the chemical reaction between the hydrocarbon fuel and air is H2O, CO2 and, in smaller quantities (depending on the proportions in which the fuel and air are mixed into the combustion chamber), some radicals like CO, OH, O, H maybe even C solid particles (also known as soot). The process is not as simple as it is taught in high school chemistry as there's no single reaction leading from reactants to final products. There are many reactions leading from the decomposition of the gasoline and air molecules to the formation of the final products (all of this reactions form the reaction mechanism). You can read more about reaction mechanisms in the related link.
Why temperature increases when combustion occures?
All combustion reactions are exothermic; that is, they release heat to their surroundings. The reason for this: a certain amount of energy is released when the chemical bonds holding the fuel together break. Some of this energy is used to form the products of combustion, which are generally water vapor and carbon dioxide. However, this recombination doesn't use up all of the energy, so the excess gets passed along to the environment, which registers as a release of heat and light.
Synthesis and decomposition reactions in an organism are called .?
All of the decomposition reactions in an organism taken together is called catabolism, while the synthesis reactions are called anabolism.
Which types of reactions are characterized by two reactants?
Bimolecular reactions involve two reactant molecules coming together to form a new product. This can include reactions such as addition, substitution, and some types of elimination reactions.
Is the sun fire or lava?
Neither. The sun is made of superheated gas, mostly hydrogen and helium. It is similar to fire in some respects, but it is not actually burning. At its core the sun carries out nuclear fusion, a process that releases many times more energy than combustion does.
Is Combustion 2 chemicals acting together?
Yes: oxygen and fuel compound react together.
Which category of chemicals reactions comes from a term that means to put things together?
Synthesis.
What are some examples of an experiment?
Experiment can be scientific or psychological. They can use samples and observations to gain insight or mix chemicals together to demonstrate reactions.
When methane is burned in the presence of oxygen the two chemical react together what is the combustion reaction?
CH4+2O2 -> 2 H2O + CO2 My caps lock is not stuck
What arer dangerous chemicals mixed together?
Mixing dangerous chemicals together can result in hazardous reactions that may release toxic gases, cause fires or explosions, or produce harmful byproducts. It is essential to follow proper handling and storage procedures for chemicals and never mix them unless you are trained to do so in a controlled environment.
Why is it necessary for humans to eat vitamins?
Everything that a human body does, all of the processes which together add up to the phenomenon that we know as life, are the result of many different chemical reactions. In order for these chemical reactions to occur in the right way, we have to have the right chemicals. Of the many chemicals which make possible the chemical reactions of life, there are some that the human body can manufacture for its own use, and others that it is not able to manufacture, and which it therefore has to obtain by eating them. Vitamins are in the latter category.
Things that produce heat?
Heating systems such as furnaces and radiators. Electrical devices like hair dryers and toasters. Chemical reactions like combustion. Friction between objects rubbing together. Human or animal metabolism.
How the light and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
How do light an dark reactions work together?
The light reactions provide energy carriers for the darl reactions.
What kind of chemical reaction are used in automobiles?
The chemical formula of the reaction in a car engine begins with combustible material usually a fossil fuel. Then a oxidizer (oxygen) is introduced and the products are water, energy, and CO2.
Is it safe to mix alcohol and Clorox together?
No, it is not safe to mix alcohol and Clorox together. Mixing these substances can create harmful chemical reactions and produce toxic fumes that can be dangerous to inhale. It is important to always follow safety guidelines and avoid mixing household chemicals.
Is Catabolism driven by synthesis reactions?
No, catabolism is driven by breakdown reactions where larger molecules are broken down into smaller units, releasing energy in the process. Conversely, anabolism is driven by synthesis reactions where smaller molecules are combined to form larger molecules, requiring energy input.
