VSEPR notation gives a general formula for classifying chemical species based on the number of electron pairs around a central atom. However, not all species have the same molecules.
For example, carbon dioxide and surfer dioxide are both species, but one is linear and another one is bent.
When the electricity flows into a tube, gas atoms crash inside producing invisible ultraviolet rays. There is a white phosphor coating that turns the invisible rays into visible light. In a plasma tv the cells are like tiny cfls only coated in phonsophers that are rgb
Matter needs to be in the state called a plasma. The sun is made of plasma, for example. A plasma is when the electrons have been stripped from the atoms.

Explanation:
When heat is absorbed by reactants in a chemical reaction then the reaction is known as endothermic reaction.
Whereas when heat is released by reactants in a chemical reaction then the reaction is known as exothermic reaction.
1. When
is positive then it means heat is absorbed by reactants and reaction is endothermic.
2. When
, this means energy of products is less than the energy of reactants. Therefore, it is exothermic in nature.
3. When energy is absorbed then reaction is endothermic.
4. When
, this means energy of products is greater than the energy of reactants. Therefore, it is endothermic in nature.
5. When [tex]\Delta H is negative then it means heat is released by reactants and reaction is exothermic.
