What is the first theory to relate chemical changes to events at the atomic level?
Dalton's Atomic Theory
Name two events involving electrons that can result in the formation of chemical bond?
Ionic bonding involves the transfer of electrons between atoms; covalent bonding involves the sharing of electrons between atoms.
Conclusion Of Chemical Bond?
That is the question we must ALL ask ourselves. What is the conclusion of our life? Is there a conclusion? Or is it just some kind of perceptual illusion of imagery where anything can happen and it's all played out by a series of events. Our human body is composed of organ systems that perform chemical reactions every day. But when the human body dies, it is the conclusion of the life and chemical reactions are made no longer.
Does all the energy start out as chemical energy?
No, our energy sources started from the sun (nuclear fusion) which made vegetation grow which turned into fossil fuels, or from stellar events which formed uranium. Then there are energy sources like wind, wave, and tidal, that are driven by the sun's energy, and direct solar energy. When we use fossil fuels, we are using a chemical reaction to release the energy contained in the fuel, but the original formation of the fossil fuel was driven by the sun. Energy from uranium is not chemical at all. Hydro power also depends on rainfall as the source of the energy, and that is caused by the sun's effect on the weather.
What is the chemical process of a hydrogen bomb?
A hydrogen bomb is a series or sequence of events that must take place in a specific order. Only a very small part of that is chemical. Conventional chemical explosives are used as the trigger to begin the sequence. Electrical detonators are activated by an electric current that creates heat in the detonator. That heat causes a small amount of explosive in the detonator to to explode. THAT explosion is chemical- an unstable chemical drops from a high to a lower energy level, giving up heat that creates a shock wave. That shock wave causes another chemical reaction- in the main explosive lenses of the bomb. Those chemical explosives ALSO drop to a lower energy level in a chemical reaction- creating a larger shock wave. That shock wave then physically crushes a mass of plutonium, and begins a NUCLEAR process- where the ultra-dense compressed plutonium undergoes nuclear fission, breaking down into lighter elements, releasing tremendous heat, shock, and free neutrons. That FISSION reaction triggers the next stage, where very light elements such as hydrogen are compressed to the point that they FUSE into heavier elements, liberating a greater amount of energy in the form of heat, blast, and radiation.
Do you know how to use a microplate reader ?
Microplate readers are laboratory equipment that are used to see if there has been any biological, chemical or physical events within a given sample. They are used by scientists.
What does the Roman colosseum say about ancient Roman religion?
The Colosseum says very little about ancient Roman religion. Although the events held there were always preceded by a religious service or dedication, which was customary for Roman events, the Colosseum itself was an entertainment center, not a temple of any kind.The Colosseum says very little about ancient Roman religion.

How are various historical events shaped the progression of subdiscipline of biomechanics?
Many historical events have shaped the subdiscipline of biomechanics. Major events such as war often are the catalysts to furthering technology. For instance, in wanting to protect soldiers from chemical or biological warfare, scientists have furthered the area of biomechanics by creating devices that protect soldiers.
Are scientists that explain events or phenomenon using natural laws instead of the supernatural?
These scientists were called "Naturalists"
What events preceded the dropping of the atomic bombs on Hiroshima and Nagasaki?
Sorry- this is not a question. Please reword and resubmit. and we will try to get you an answer- but you have to do your part.
Major events 1997?
Scientists clone Dolly the sheep
Do most scientists believe that reports of strange events inside the Bermuda triangle are accurate or true?
No, most scientists do not.
Earth scientists assume that the causes of natural events or phenomena can be determined by?
answer it
Why is it important for scientists to be objective?
If scientists are not objective, they will not be able to interpret the information they discover correctly.Let's try an example. Suppose a scientist was convinced that a chemical he invented would be harder than a diamond. If he was an objective scientist, he would test the chemical and be honest about whatever results he found. If he was not objective, he would interpret any information as proof that the chemical was harder than a diamond - or he would say that something went wrong in the experiment if it didn't prove that.
What cultural events preceded Romanticism?
Some cultural events that preceded Romanticism include the Age of Enlightenment, which emphasized reason, individualism, and skepticism of authority. The Industrial Revolution also had a significant impact by transforming society and reshaping the way people lived and worked. Additionally, the French Revolution sparked a wave of social and political change that influenced the Romantic movement.
Scientists use statistics to?
Find the likelihood of events whose outcomes include an element of uncertainty, or to find the measure of uncertainty in the outcome of events.
