Nuclear fusion reactions. This is where an atomic nucleus (or neutrons/protons) are forced together with another nucleus to form a heavier nucleus (a new and heavier element). this needs a huge amount of energy (temperature), but when it is achieved, a large amount of energy is then released. This is what happens in the sun, hydrogen is fused together to form helium, releasing a large amount of solar energy in the process.
Some heavier elements can be made in the same way, but require even more energy. The heaviest elements such as gold, Uranium, molybdenum Niobium etc.. can only be created when a very large star explodes as a super nova.
What else can I help you with?
How does temperature affects reaction rate?
if the reaction is exothermic (creates heat) then adding heat will cause the reaction to run in the reverse direction if the reaction is endothermic (requires heat) then heat will speed it up
A reaction in which energy is taken in?
An endothermic reaction is one in which energy is taken in from the surroundings to drive the reaction. This type of reaction requires an input of energy to proceed. It often results in a decrease in temperature of the surroundings.
Which compound in the table requires the highest temperature to make it decompose?
To determine which compound requires the highest temperature for decomposition, one would need to analyze the activation energy or stability of the compounds listed in the provided table. Generally, compounds with stronger bonds or more complex structures tend to decompose at higher temperatures. If you can share the specific compounds from the table, I can help identify the one that decomposes at the highest temperature.
Why was the highest rise in temperature obtained with magnesium and copper sulphate?
because magnezium is more reactive
What is a reaction in which energy is taken in?
An endothermic reaction is a reaction in which energy is taken in from the surroundings, resulting in a decrease in temperature of the system. This type of reaction requires an input of energy to break bonds in the reactants and form bonds in the products.
During the course of which type of reaction is energy consumed?
Any reaction that consumes energy, or has a positive delta(H), is called an endothermic reaction.
An endothermic reaction is one in which heat is transferred from the surroundings to the reactants?
An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, causing a decrease in temperature. This type of reaction requires an input of energy to proceed.
Is a reaction in which energy is absorbed?
A blank reaction is a reaction only for testing, to establish a zero line, for calibration, etc.
When water and ammonium nitrate mixed the temperature decreases. what type of reaction is this and why?
This is an example of an endothermic reaction. In an endothermic reaction, heat is absorbed from the surroundings, causing a decrease in temperature. In this case, the dissolution of ammonium nitrate in water requires energy input to break the bonds between the particles, resulting in a decrease in temperature.
Can protons move from atom to atom?
It is possible only via nuclear reaction and generally requires extreme conditions such as high temperature
What is a reaction that requires heat?
Endothermic reaction
What is europa's highest temperature?
Europa's highest temperature is 690ºc
