What type of reaction is characterized by a release of energy?
The general term for a chemical reaction that releases heat is an exothermic reaction. The energy released is called enthalpy.A reaction that releases energy is called an exothermic reaction.
State wether a nuclear fusion is a chemical reaction or a nuclear reaction?
Nuclear
Is evaporating sea water a physical chemical or nuclear change?
Evaporating seawater is a physical change. Physical changes affect the form, but not the chemical makeup of a substance. The sea water is undergoing a change in states of matter, not a chemical reaction. You can undo the change by condensing the evaporated water .
Is nuclear fission a physical or chemical change and why?
Nuclear fission is a physical change because it involves the splitting of atomic nuclei to release energy, without altering the chemical composition of the atoms involved. In contrast, chemical changes involve the rearrangement of atoms to form new substances with different chemical properties.
What does NOT describe a nuclear reaction?
A nuclear reaction does not involve the breaking or forming of chemical bonds between atoms. Instead, it involves changes in the nucleus of atoms, such as nuclear fission or fusion. Additionally, a nuclear reaction does not typically release energy through the rearrangement of electrons in an atom's outer shell like a chemical reaction does.
What type of reaction is characterized by a release of energy?
The general term for a chemical reaction that releases heat is an exothermic reaction. The energy released is called enthalpy.A reaction that releases energy is called an exothermic reaction.
Is fusion a type of chemical reaction?
False
State wether a nuclear fusion is a chemical reaction or a nuclear reaction?
Nuclear
How much more powerful between chemical and nuclear reactions?
A nuclear reaction is much powerful than a chemical reaction.
Does the explosion in a nuclear bomb count as a rapid chemical reaction?
No, a nuclear bomb involves a nuclear chain-reaction.A chemical reaction involves the orbiting electrons in an atom.A nuclear reaction involves the nucleus (hence "Nuclear") of an atom.
Is fusion chemical nuclear or mechanical?
Fusion is a nuclear reaction.
What chemical reaction produces heat and energy in a star?
it is not a chemical reaction. It is a nuclear reaction and it is called fusion.
Is it a chemical reaction or a nuclear reaction when two compounds are combined heat is realeased?
Chemical.
Is a change that produces a new element a physical change?
No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.
What happens when it releases enough energy?
When an object releases enough energy, it can result in various outcomes depending on the context. For example, in the case of a nuclear reaction, a significant release of energy can lead to an explosion. In a chemical reaction, releasing enough energy can cause a change in temperature or the formation of new substances.
Is evaporating sea water a physical chemical or nuclear change?
Evaporating seawater is a physical change. Physical changes affect the form, but not the chemical makeup of a substance. The sea water is undergoing a change in states of matter, not a chemical reaction. You can undo the change by condensing the evaporated water .
Is conversion by radioactive decay a chemical reaction?
No. It is a nuclear reaction - radioactive disintegration.
