Pronto! The community is already created! By tomorrow I should have someone. I would not expect much.

As well, Eduardo?! A community on the internet about chemistry. Oxy, and what about it?!

Dunno if it was about photography. He’s talking about is because almost no one did well in chemistry.

you saw the notes in the last race? A horror!

No, Luiza! The community already has us!

Let me see shit! I have not spoken? There’s a guy there’s Acre!

Questions are coming here! We have to write something.

I’ll take my notebook! Is the whole story of last year.

Feature: content of a class or a synonym for the discipline of a particular teacher.

For science, matter is everything that has mass and occupies space.

There are people here confused with chemical physics.

Zeca writes there of Natal, Rio Grande do Norte. Christmas is great.

He remembers playing a teacher who talked about the difference between chemistry and physics, saying that chemistry is “changing”.

Makes sense. When you have a change in substance, we are actually talking about chemistry, not physics.

And when the ice melts, for example? What about it? It did not change the solid liquid pro?

Changed the state of matter, not substance.

Is the water that remained was solid water after turning back the net.

Want an example of this difference? The lamp and candle.

The two lights, but so what?

You’re talking about substance, huh? This. The substance remains the same.

The candle lights also. But the changes are visible, and paraffin wick burn and there are new substances.

The lamp goes back to what it was in the beginning “and not sailing. It has to do this.

It’s good to put these explanations in the community, right?

Yes, we copy the part of the Christmas Zeca there and talks about the lamp and candle.

Copy?! I thought we’d have to create all the answers.

But his explanation is excellent, is not it? We will. “In nature nothing is created, nothing is lost, everything changes.”

Who said that “in nature nothing is created, everything changes” was the French chemist Antoine Laurent Lavoisier.

The phrase “In nature nothing is created, nothing is lost, everything becomes” is attributed to the French chemist Antoine Laurent Lavoisier.

But in fact, an interpretation is built over time from their ideas.

Considered the father of modern chemistry, Lavoisier published the “Treatise of Elementary Chemistry” in 1789.

Their experiences and discoveries opened the way for the development of chemistry fundamentals and significant advance in a language that made the study of chemistry more easily understood than heretofore.

Who knew, the community already has more than one hundred people! I liked that guy there Pinion. Where is Jatropha?! In Paraná!

Aloo! I’m from Santa Catarina, forgotten? Coladinho in Paraná? But because you liked Boy Pinion, Eduardo?

Ah, because he is like me. Lost dog is more than in moving day.

But are interested! Has not he sent the question of the chemical reaction?

That’s right! And we have to search!

I guess I do not know to recognize a chemical reaction.

You know yes. Most times, only to give notice to realize.

The bodywork of a car when a metal rusts, the smell when a fruit rot.

Are chemical reactions! The evidence of chemical reactions taking place.

My sister was blonde overnight. Must have rolled a chemical reaction!

It is my dear! Hydrogen peroxide in hair is a good example yourself!

Nobody in the lab. Is that it’s time for lunch. But we must explain “how to define a chemical reaction” back in the virtual community.

Let’s think. We want a good example, not too complicated? Let’s eat first.

I can help! Good! Eduardo, he’ll take up the food.

I can help you find a good example of a chemical reaction! Oh, sorry! This guy is talking about food.

But a chemical reaction is happening here in my belly! Calm down, Edward! That example can be cool?

You can solve two problems at once: his hunger and research! I did not understand, but I’m enjoying it. How so?

Have you thought about how many chemical reactions take place in a kitchen?

Great idea! Of course. Thank you for the tip!

Joel! Working here in the lab! Thanks again, Joel!

How about a closer look at some chemical reactions in a kitchen?

Just do not huh? Ô hungry goat.

Notice what happens during the burning of methane, the primary constituent of natural gas.

During the firing, the reaction occurs between methane and oxygen in the air. This reaction arise water and carbon dioxide.

Already during the fermentation of the cake, the reactions are somewhat more complex. Look, the yeast is composed of two substances: the dihydrogen phosphate, calcium hydrogen carbonate and sodium.

In the presence of water, these two compounds react and form elements, reacting with water, generating hydrogen phosphate, calcium hydrogen phosphate, sodium and carbonic acid that decomposes in hot water and carbon dioxide.

The release of carbon dioxide in gaseous form, is what produces those “holes” in mass, making the pie grow larger.

How much stuff you found! The thing is to talk to who understands the subject.

I still prefer to go photographing you! Very funny.

But it still lacks much research on chemical reactions, the factors that trigger the classification characteristics of the reactions.

It still will be researched and very well explained in the virtual community.

Write on! Today we saw Bruno, Luiz Eduardo and create a virtual community on the Internet chemistry.

We know some examples of chemical reactions so common in our day-to-day.

And we saw how the reactions occur in baking powder and the burning of methane. Besides hearing some valuable tips for our health and the environment.

Keep an eye on your world around. Because “There is chemistry.”
