The general term is "nuclear reaction". An atom may emit alpha, beta, or gamma rays; it may split into two or three smaller parts (fission), or two lighter atoms may combine into a heavier one (fusion).

Is melting of lead a chemical reaction?

No, melting of lead is a physical change, not a chemical reaction. A chemical reaction involves the breaking and forming of chemical bonds to create new substances, while melting only involves a change in state from solid to liquid with no change in chemical composition.


How can one determine the enthalpy change of a reaction, specifically, how to find delta H of a reaction?

To determine the enthalpy change of a reaction, you can use Hess's Law or measure it experimentally using calorimetry. Hess's Law involves adding or subtracting the enthalpies of known reactions to find the overall enthalpy change. Calorimetry involves measuring the heat released or absorbed during a reaction to calculate the enthalpy change.


Zinc reacting with copper sulfate to produce copper and zinc sulfate isn't an example of transmulation why?

This reaction does not involve a change in the atomic nucleus of the elements involved. The chemical reaction only rearranges the atoms to form new compounds while the elements themselves remain the same. Transmutation involves changing one element into another by altering the number of protons in the nucleus, which does not occur in the zinc-copper sulfate reaction.


How can one determine the enthalpy of a reaction?

To determine the enthalpy of a reaction, one can use Hess's Law or measure the heat released or absorbed during the reaction using a calorimeter. Hess's Law involves adding or subtracting the enthalpies of known reactions to find the enthalpy of the desired reaction. Calorimetry involves measuring the temperature change of the reaction and using it to calculate the enthalpy change.


Why is a phase change not a chemical reaction?

A phase change is a physical change that involves rearranging the molecules in a substance without changing its chemical composition. In contrast, a chemical reaction involves the breaking and forming of chemical bonds, resulting in the formation of new substances with different chemical compositions.

How does nuclear reaction differs from ordinary chemical reactions?

It involves the particles of the nucleus (protons and neutrons), not the electrons.


Which part of atom take part in nuclear reaction?

The nucleus of an atom is the part that takes part in nuclear reactions. It consists of protons and neutrons, which are involved in processes such as fission and fusion. The electrons surrounding the nucleus are not typically involved in nuclear reactions.


What parts of an atom can change during a nuclear reaction that can't change in a chemical reaction?

the number of protons and neutrons


Freezing involves a chemical reaction?

No, freezing involves phase change, which is a physical change. There is no chemical reaction, as the basic chemistry is unchanged it is still the same material in a different physical state.


What involve a chemical chemical change?

Chemical reactions involve a change in the chemical composition of the reacting substances.


Why is a transmutation calssified as a nuclear reaction?

because that's what it takes to change one element to another, a change to the nucleus.


What does a transmutation reaction always have to involve?

A transmutation reaction always involves a change in the identity of the atoms involved, resulting in the formation of different elements. This can be achieved through processes like radioactive decay or nuclear fusion.


What is another term for chemical change?

A chemical change is also referred to as a chemical reaction. It typically involves the transformation of substances into new substances with different chemical compositions.
