Posters fading is a chemical change.
The chemical properties of the poster originally reflected a lot of light, but when they fade (usually due to overextended sunlight exposure), the chemical properties of the poster change to reflect less light.

Framing a poster is a physical change because it does not alter the chemical composition of the poster or the frame itself. The poster and frame retain their original properties even though they are now combined.

Do a poster what is neutralisation?

What compound is NiPO4?
NiPO4 is Nickel (III) Phospate. The PO4 is a polyatomic particle which is called phosphate and has a charge of 3- and in this example Ni has a charge of 1+, so the charges are switched giving Ni a 3+ charge with stays positive and is written in the middle of the two names. [edit] Not quite... the nomenclature Nickel (III) indicates the Nickel has a charge of 3+. Nickel will either have a charge of 2+ or 3+, it can not have a charge of 1+, so I don't know what the original answerer was saying with switching charges bumping up the ionization of the Nickel. Basically, Ni3+ + PO43- -> NiPO4 OR if you are dealing with Nickel (II) Ni2+ + PO43- -> Ni3(PO4)2 which is also Nickel Phosphate Any way, I just wanted to correct the original post, but the answer to the original question is Nickel Phosphate, or as the original poster stated Nickel (III) Phosphate. -Mike
Why will the acid explode when you mix water into acid?
Mixing water into acid can cause an exothermic reaction, leading to a rapid release of heat that can create a burst of steam and potentially splatter the acid. This is why it is important to add acid to water slowly and carefully to control the reaction and prevent an explosion.
