Answer : The chemical symbol for the element that results from this process is, (Ar) for argon.
Explanation :
Electron capture : In this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. Simply, a proton and an electron combines together to form a neutron. Mass number does not change in this process.
The equation for the given reaction is,
Thus, the chemical symbol for the element that results from this process is, argon (Ar).
Answer:
CO2
Explanation:
- There are two types of molecules
- Polar
- Non polar
Non polar molecules are insoluble in water .
Every chemical reaction requires a minimum amount of energy to undergo reaction.
The total energy required is Threshold energy. The chemicals have some internal energy and they require some extra energy which is known as activation energy.
The reaction occurs when two molecules or atoms come closer to each other and for this they need kinetic energy.
Now for an effective collision the two molecules or atoms should collide with a minimum amount of energy so that they may undergo reaction so again they need some energy
These kinetic energy and energy for effective collision is actually called as activation energy.
