It's zinc.

I'd say zinc.

It's not different, it's the same stuff calcium carbonate, calcium carbonate.

Oh, then sodium carbonate

This metal is called zinc.

And they said, calcium carbonate.

There's consequences for carbonate organisms.

No. It's nothing. I'm taking zinc.

Solid zinc, okay. And And bring me

Do you think the zinc really works?

Brass is an alloy of copper and zinc.

Brass is an alloy of copper and zinc.

Oxygen, hydrogen and zinc have their own signature.

It has to be galvanized or solid zinc.

They can pull calcium out of the environment, and put down a layer of calcium and then carbonate, calcium and carbonate.

The main framework material of coral reefs is calcium carbonate.

But it's not just the carbonate producers that are affected.

We're flying through 2,000 lattice of atoms oxygen, hydrogen and zinc.

It's four blue zinc atoms bonding with one white hydrogen atom.

And I said, that's what this is this is calcium carbonate.

When you evaporate seawater, the first thing to crystallize out is calcium carbonate.

Oh, by the way, just in case you weren't already guessing, it's calcium carbonate.

Everything you see in this picture is commercial grade copper, lead, silver, zinc and gold.

There are many organisms that build their shells out of calcium carbonate plants and animals both.

Basically, about half of the world's population is lacking in iron, zinc, iodine and vitamin A.

Here's the first battery a stack of coins, zinc and silver, separated by cardboard soaked in brine.

Here, we've got a protocell to extract carbon dioxide out of the atmosphere and turn it into carbonate.

This abalone shell is a biocomposite material that's 98 percent by mass calcium carbonate and two percent by mass protein.

We can analyze the carbonate that makes up the coral, and there's a whole bunch of things we can do.

Because the lowly abalone is able to lay down the calcium carbonate crystals in layers, making this beautiful, iridescent mother of pearl.

And that builds up on the evaporators and that's what that image on the left is gradually getting encrusted with the calcium carbonate.

Because in Mine golia, Chinese firms operate and own most of the mines copper, zinc, gold and they truck the resources south and east into mainland China.

Now if you look at the top of the slide, you will see that two thirds of us do not take in enough calcium, magnesium, zinc or iodine.

Aluminum buffer action, aluminum hydroxide is what we think it is, uh, plus the barium carbonate, strontium titanate, strontium oxides, barium oxides, probably some aluminum oxides in there.
