Building infrastructure in the Pokémon world

The people from Kong Family Village were invited into the classroom of Mu Guan and others.

After a few polite words.The Kong family began to look around.I want to see the truth from the subtleties as quickly as possible.

"What is this?" Kong Wenxue asked as soon as he entered the classroom, pointing to the projector.

"A projector. You can simply think of it as a canvas, which can project pictures on it." Mu Guan explained in the simplest tone.

After listening to Mu Guan's explanation, Kong Wenxue and others stood in front of the projector and observed this thing for a long time.

"What is this room used for?" Kong Wenhua asked.

"Class." Yan Fan asked casually. The few of them had gradually become calm and calm from being excited at the beginning.

Attend class!

Kong Wenhua's eyes lit up. This room was actually used for classes?

"It's the place to teach you knowledge?" Kong Wenhua confirmed again.

"Yes." Shui Leshan replied.

"Is this room used to teach you knowledge? Or is the entire building used to teach you knowledge?" Kong Wenhua asked in great detail, trying to see what kind of person Shi Hao was from these little things.

"The whole yard is used for classrooms." Tu Yuan replied honestly: "From the teaching building, to the west building, the north and south buildings, and the east building. They are all used as classrooms."

Hearing this, everyone in the Kong family village, including Kong Wenxue and Kong Wenhua, were surprised and delighted.

"I didn't expect that the owner here pays so much attention to knowledge and education."

"He doesn't come from our Kongjia Village, right? Or is he the descendant of a daughter who married outside our Kongjia Village?"

"It must be influenced by us, otherwise we wouldn't pay so much attention to education."

"Such a big place, such a beautiful building, all used to teach knowledge? This is the behavior of our Kong family!"

People in Kongjia Village were talking a lot. After hearing Shi Hao's grand operation, they wanted to regard Shi Hao as a member of Kongjia Village.

"The owner here is very likely to be on the same journey as us." Kong Wenxue also made the same judgment.

Although Kong Wenhua still maintains his own identity, he also made a conclusion: "Maybe the paths are different, but the ultimate goal is still the same."

Obviously, Shi Hao used the most beautiful and magnificent place in the entire camp as his academy, which was greatly recognized by the people of the Kong Family Village.

"Then who will teach you?" Kong Wenxue asked curiously. Could it be that the principal came to teach in person?

"It." Tu Yuan said naively, pointing at the projector.

"It? What can it teach you? Then what did you learn?" Kong Wenxue asked in an incredible tone.

"You can learn whatever you want to learn! Of course, you should learn something useful to you." Tu Yuan replied calmly.

Hearing Tu Yuan's answer, everyone in Kongjia Village showed embarrassment, embarrassment and speechlessness on their faces.

They hesitated to speak, wanting to persuade Tuyuan and others to take the right path, but they were worried about the identity of their guests, so they hesitated and finally looked at Kong Wenhua.

"Nonsense!" Kong Wenhua roared loudly.

All eyes were on Kong Wenhua.

Sure enough, it was Kong Wenhua who had to do this kind of offending.

"You are just fooling around! There is such a good place and such good conditions. You actually just look at a piece of cloth to study? What do you want to learn? What can it teach you?" Kong Wenhua was so angry that his beard was trembling, If Shi Hao stood in front of him, he would probably give Shi Hao two slaps.

Desperate things.

It’s simply misleading!

Kong Wenhua couldn't bear it anymore.

"Where is your director? Let him come to see me. See what he has done? What is he doing? It's such a waste of such a good place and such a waste of your good years. It's... it's outrageous for both humans and gods." Kong Wenhua roared.

"Shut up!" Mu Guan, Yan Fan, Shui Leshan and Tu Yuan all shouted back at Kong Wenhua.

It's okay to insult them.

But it is not okay to insult the academy or the principal!

Several people glared at Kong Wenhua, and the atmosphere at the scene became tense for a moment.

Just when everyone was about to stop talking.

The projector in the classroom began to play the picture.

I saw a picture of iron ore appearing on the projector.

The narrator on the side began to dub: "What is iron ore? Any ore that contains economically usable iron is called iron ore.

There are many types of iron ore, the main ones used for iron making are magnetite, hematite and siderite.

After the iron ore sample is dissolved by hydrochloric acid, the iron in it is converted into Fe3+. Under strong acidic conditions, Fe3+ can be reduced to Fe2+ by SnCl2.

After Sn2+ completes the reduction of Fe3+, methyl orange can also be reduced by Sn2+ to hydrogenated methyl orange and fade. Therefore, methyl orange can indicate the end point of Fe3+ reduction.

Sn2+ can also continue to reduce hydrogenated methyl orange to N, N-dimethyl-p-phenylenediamine and sodium p-aminobenzenesulfonate.

All in all, iron ore is a very important resource. "

Everyone fell silent as something played on the projector.

Especially the people in Kongjia Village, each of them opened their mouths wide, not knowing how to express their shock.

"This? What does this mean?" Kong Wenxue asked puzzled.

"Why did it suddenly have a picture? Why did you put this up all of a sudden?" Kong Wenhua followed suit and asked.

I saw that the two of them had just finished speaking when someone entered text on the projector.

"A detailed classification of iron ore?"

As the questions were entered, answers quickly popped up.

“Iron ore is mainly divided into several categories:

One, magnetite. It is an iron oxide ore whose main component is Fe3O4, which is a complex of Fe2O3 and FeO.

It is black-gray, with a specific gravity of about 5.15, an iron content of 72.4%, an oxygen content of 27.6%, and is magnetic.

Magnetic separation can be used in mineral processing, which is very convenient to process.However, due to its fine structure, its reducibility is poor.

After long-term weathering, it turns into hematite.

The second is hematite.

It is also an iron oxide ore, the main component of which is Fe2O3.

It is dark red, has a specific gravity of about 5.26, an iron content of 70%, and an oxygen content of 30%.

Is the most important iron ore.

According to its own structure, it can be divided into many categories, such as red hematite, specular iron ore, mica iron ore, clay hematite and so on.

Third, limonite.

This is an ore containing iron hydroxide.

It is the collective name for two ores with different structures: goethite HFeO2 and lepidite FeO. Some people also write the chemical formula of its main component as mFe2O3.

It is khaki or brown, contains about 62% iron, 27% oxygen, and 11% water, with a specific gravity of about 3.6-4.0, and is mostly attached to other iron ores.

Fourth, siderite.

It is an ore containing ferrous carbonate, the main component is FeCO3, appears blue-grey, and has a specific gravity of about 3.8.

This ore probably contains considerable amounts of calcium and magnesium salts.

Since carbonate absorbs a lot of heat and releases carbon dioxide at a high temperature of about 800 to 900C, most of us roast this type of ore first and then add it to the blast furnace. "

During the video, no one spoke.

Everyone in Kongjia Village stared at the screen intently.

Their hearts were shaken violently, they couldn't believe it, incredible, curious, and crazy.

Various emotions are staged in their hearts in turn.

"It's... a monster?"
