Energy levels inside an are the specific that electrons can have when occupying specific orbitals. Electrons can be excited to higher by absorbing from the surroundings. Light is emitted when an electron relaxes from a high state to a lower one.
Explanation:
Intermolecular force s between particles in a matter holds particles of molecules together in substances.
- The stronger the intermolecular forces the more solid a substance is.
- The weakest intermolecular attraction are found in gases as they have negligible attractive forces in between their particles.
- Solids are held together by very strong attractive forces.
- Liquids have weak forces holding them in place and this allows for a little movement.
- Gases are typically have very weak to negligible attractive forces.
According to Law of conservation of matter," matter can neither be created nor destroyed but is conserved and remains constant over time'.
In above picture let suppose the Blue balls represent N₂ molecule and White balls represent H₂ molecules.
So, left picture represent reactants,
2 N₂ + 6 H₂
And , right picture represent products,
4 NH₃
So, there are 4 N atoms and 12 Hydrogen atoms in reactants and 4 N atom and 12 Hydrogen atoms in products. Means the mass of elements is conserved. The overall reactions is as follow,
2 N₂ + 6 H₂ → 4 NH₃
Result:
Yes! This reaction follow Law of conservation of Matter.
