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.
Neutralisation is a chemical reaction between an acid and a base that results in the formation of water and a salt. It is a common way to balance the pH levels of a solution. In the process, the acidic and basic properties of the initial substances are canceled out, leading to a neutral outcome.

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
Yes. CaO is an ionic compound.
It won't explode, since the water makes the acid less dense, making it not explode. Thanx. I hope this helps. The answer provided by the previous poster is not entirely correct. It may not explode in the sense of an accelerating chemical reaction, but the rapid boiling of the water being added to the acid sure comes close! The enthalpy of mixing of acid and water is usually VERY exothermic. If you add the water directly to a strong acid, the heat released by the mixing process cann be more than sufficient to boil the water - which means that it can quickly generate bubbles of steam below the surface of the acid and "explode" as the bubbles coalesce into bigger bubbles and expand with all the heat being released. If the vessel where the mixing is occurring doesn't allow for the quick escape of the steam, it will build up pressure and can explode the vessel - spraying acid all over - not a pleasant thing to have happen to say the least! I once made the mistake in an organic chemistry lab of mistakenly grabbing a bottle of concentrated sulfuric acid (a very strong acid with a high enthalpy of mixing) instead of the bottle of glacial acetic acid (think concentrated vinegar - much lower enthalpy of mixing) that was located next to it. When I tried to quickly mix 50 ml of water with 50 ml of acid, the mixture in the beaker rapidly boiled, spilling over onto my hand burning it with first degree burns from the heat and chemcial burns from the acid and splashing all over the general area (I found holes in the tops of my shoes later). Fortunately I was following the standard rules of the lab and was wearing my lab apron and safety glasses. I ran to the sink and ran the water over my burned and dehydrated hands (sulfuric acid will suck the water out of your skin rather effectively). I can therefore attest personally to what happens when you try to mix acid and water quickly!
"Allposters.com is probably the best site on the internet for all things poster prints, framing or anything like that." Art.com is a great site for poster prints. They have everything!
Physical properties: paint is a thick colored liquid with a distinct smell. Chemical properties differ depending on the paint...poster paint, oil-based house paint and car paint have vastly different chemical properties, but they're all paint.
It is a type of sturdy poster board, which has regular poster board on the outside and a core of lightweight, compacted foam in the middle. This makes a sturdy presentation board. It's great for kids' school projects, signs, any type of display, really. It's also used in framing.
Because they have chemical compositions that turns into a paint monster and will attack you.
3 reasons to print out pictures you took with your digital camera? Framing the picture and hanging it on your wall or putting it in your wallet, making a poster for your wall, using the picture for a greeting card cover, making calenders, attaching it to a poster for a presentation, etc.
You can find a 28x34 poster frame at various retailers, including online stores like Amazon, Walmart, or Target. Specialty framing shops or art supply stores may also carry custom sizes. Additionally, websites like Etsy or local craft fairs might offer unique options. Be sure to check the measurements to ensure they fit your poster correctly.
