Melting #2: Copper (II) Sulfate (Didn’t Work)

Melting #2: Copper (II) Sulfate (Didn’t Work) The last time we melted sulfur, and it was really fun (except for cleaning the test tube). Now let’s melt something else, what about Copper Sulfate? Copper (II) sulfate is the inorganic compound with the chemical formula CuSO4. Older names for this compound include blue vitriol, bluestone, vitriol of copper, and Roman vitriol. The pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue. Melting Point: 110 °C (230 °F) Sulfur’s melting point is 5 °C higher (which means they’ll melt about the same time). It looks impossible to melt it because the sulfur is more (soft) like a… Read more Melting #2: Copper (II) Sulfate (Didn’t Work)

I Figured out why the Coins look Different

I Figured out why the Coins look Different Remember the coin experiment that I performed lately? When I washed the coins, they looked different. But why? I finally figured out the answer. Copper metal is oxidized by the Ag1+ to Cu2+ and the Ag1+ ions are reduced by the copper metal to silver metal. But do you remember what the coins are made of? Penny: The alloy remained 95 percent copper and 5 percent zinc until 1982, when the composition was changed to 97.5 percent zinc and 2.5 percent copper (copper-plated zinc) until now. Cents of both compositions appeared… Read more I Figured out why the Coins look Different

Why can’t Chickens Fly?

Why can’t Chickens Fly? Most chicken breeds are still able to fly short distances. For example, flying up into a tree (that’s where they would naturally roost), or to escape a predator. They certainly are not good at flying, though. There are two reasons for that. 1. Ancestry Chickens were bred from a wild species call the red jungle fowl. These jungle fowl are a little more adept at flying than chickens are now, but they are fundamentally more adapted for a ground-based life All of their food is located on the… Read more Why can’t Chickens Fly?

Leaf Fish

Leaf Fish Do you know what camouflage is? Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see (crypsis), or by disguising them as something else (mimesis). Examples include the leopard’s spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid‘s wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance… Read more Leaf Fish

Are Video Games Bad for You?

Are Video Games Bad for You? Introduction: The last time I did a post about Why Kids Should Study Science. And it has 6 views and four likes but maybe it has more now. Anyway, now my question is: Does video games make your brain think slower? Good question right? And on this post I’ll try to find the answer to this question from internet. So let’s get started. Also, try to read the whole post please if you’re interested. The first video game was created in October 1958, Physicist William Higinbotham… Read more Are Video Games Bad for You?
