Explanation:
Sodium has atomic number of 11 and its electronic configuration is given by:
![[Na]=1s^22s^22p^63s^1](https://tex.z-dn.net/?f=%5BNa%5D%3D1s%5E22s%5E22p%5E63s%5E1)
The nearest stable electronic configuration to sodium is of the neon. So, in order to attain stability of noble gas it will loose its single electron.
![[Na^+]=1s^22s^22p^63s^0](https://tex.z-dn.net/?f=%5BNa%5E%2B%5D%3D1s%5E22s%5E22p%5E63s%5E0)
Sodium has single valency that is 1.
Let nbe the valency of the ion 'X'
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
So, the formulas for all the possible compounds that sodium can form with the other ions will be:
Based on ecological studies, the definitions below applies to the given terms:
- Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
- Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
- Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
- Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available
<h3>What is ecology and what are some terms in ecology?</h3>
Ecology is the study of living things and their interactions with their environment.
Some terms in ecology include:
- Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
- Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
- Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
- Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

Due to lava which heats water where water vapour is comes
Answer:
Some energy is lost as heat
Explanation:
It is correct to say that as the gasoline is converted to mechanical energy in the automobile engine, some of the energy is lost as heat.
Heat energy is on of the ways energy is lost in any system. The movement of mechanical parts and even the combustion of the gasoline produces heat energy.
These energy are usually lost to the environment.
Answer:
Activation energy is needed so reactants can move together, overcome forces of repulsion, and to begin breaking bonds.
Explanation:
