What is a Catalyst mean in chemistry?
In Biology, a catalyst is a substance which speeds up a chemical reaction, without being changed themselves. Biological catalysts are found in living organisms.
What chemical reaction occurs when an airbag is inflated?
When an airbag is inflated, a chemical reaction involving the rapid decomposition of sodium azide (NaN3) occurs. This reaction produces nitrogen gas (N2) which rapidly fills the airbag, causing it to inflate quickly to protect the occupants of the vehicle in the event of a collision.
What is the meaning of reaction?
Any action in resisting other action or force; counter tendency; movement in a contrary direction; reverse action., The mutual or reciprocal action of chemical agents upon each other, or the action upon such chemical agents of some form of energy, as heat, light, or electricity, resulting in a chemical change in one or more of these agents, with the production of new compounds or the manifestation of distinctive characters. See Blowpipe reaction, Flame reaction, under Blowpipe, and Flame., An action induced by vital resistance to some other action; depression or exhaustion of vital force consequent on overexertion or overstimulation; heightened activity and overaction succeeding depression or shock., The force which a body subjected to the action of a force from another body exerts upon the latter body in the opposite direction., Backward tendency or movement after revolution, reform, or great progress in any direction.
Why is the burning gasoline in a car a chemical change?
Chemistry is just a subset of physics in general. A chemical event is the interaction of electrons of one atom with neighbouring atoms. For certain such interactions to take place, energy has to be added. Heat causes the molecules of gasoline to break apart and recombine with oxygen in the air. This in turn releases more energy, so the reaction continues around it as long as there is gasoline and oxygen available. Heat is really just "more frantically moving atoms". With sufficient movement, the energy causes chemical bonds, i.e. the configuration of electrons between atoms, to break or be made.
What is meant by chain reaction in nuclear reactor?
Basically a chain reaction (nuclear or chemical) is a self sustaining auto-catalytic reaction.In a nuclear reactor it is a neutron chain reaction, where each neutron released in every fission event can trigger another fission event. In a nuclear reactor the excess neutrons must be disposed of, which is the purpose of the control rods so that the reaction can be kept at some desired constant rate.
What can happen to the energy when an event takes place?
During an event, energy can be transformed from one form to another. For example, in a chemical reaction, energy can be released or absorbed. Additionally, energy can be transferred between objects or systems during an event.
What is chemical cascade?
A chemical cascade refers to a series of chemical reactions that are triggered by a specific event, leading to a chain reaction of biochemical processes. These cascades are often involved in signal transduction pathways within cells, where a molecule binding to a receptor initiates a series of reactions that ultimately produce a cellular response.
What is a catylast?
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. a person or thing that precipitates an event.
What is evolution by a chance event called?
I think you want genetic drift. That is a random event, which is subtly different than a chance event, though a chance event, such as an unforeseen accident can be part of it. Accidents always happen by chance, but to be random they happen in no set numerical order.
What is a Catalyst mean in chemistry?
In Biology, a catalyst is a substance which speeds up a chemical reaction, without being changed themselves. Biological catalysts are found in living organisms.
How does the essay i just couldn't put it down describes the plot?
As a chain reaction of a series of events in a story
Is probability always a fraction?
Only when an event is probability to happen between a range of 1 to 0 then it is a fraction.
An event that will definitely happen is an event with what percent probability?
An event that will definitely happen is an event with 100% probability.
Can -1.5 be the probability of an event?
No. The probability of an event ranges from 0 (the event will not happen) to 1 (the event will happen).
What is a probability of 0 which means the event has to happen?
If the probability of an event is zero then that event cannot happen
What is a step that makes up a reaction?
A step that makes up a reaction is a specific molecular event that occurs during the chemical transformation of reactants into products. Each step involves the breaking and formation of chemical bonds between atoms to create new substances. These individual steps collectively make up the overall reaction mechanism.
What chemical reaction occurs when an airbag is inflated?
When an airbag is inflated, a chemical reaction involving the rapid decomposition of sodium azide (NaN3) occurs. This reaction produces nitrogen gas (N2) which rapidly fills the airbag, causing it to inflate quickly to protect the occupants of the vehicle in the event of a collision.
