Not long ago, we got a wall newspaper and found two or more blue and white porcelain with chemical terms on it.
Super funny singing is fun and can stimulate interest.
I don't know which chorus part you want to summarize the properties of a chemical substance.
Chemical blue and white porcelain
(metal ion correlation)
Blue flocculent precipitate jumps to the bottom of the test tube.
Copper ions will never separate when they meet hydroxyl groups.
When the solution is golden yellow, because iron is trivalent
Light green ferrous iron is fascinating.
(acetylene related)
Calcium carbide sneaks around to produce acetylene gas.
After ignition, the acetylene flame becomes a high temperature of several thousand degrees.
Evaporating carbon dioxide
Lime water adorns the white sink.
(benzene related)
Benzene is not easy to change color when it meets potassium permanganate.
Nitro groups are added to toluene. Watch out for TNT.
How beautiful the purple color of iodine molecules in benzene is.
This laid the foundation for extraction.
(electrochemical correlation)
The electrolyte of the electrolytic cell is electrified through the anode and the cathode.
The price is transferred from high and low electrons.
Refining copper, iron, zinc, manganese, nickel, chromium, aluminum, silver and tin.
Leave anode mud
(diluted with concentrated acid)
Dilute concentrated sulfuric acid and inject it into water.
Slowly pour the stirring hand along the wall.
Immediately wash the skin with plenty of water and concentrated acid.
Use sodium bicarbonate for emergency treatment.
(Actual output)
Glycerol moisturizes the skin smooth and delicate.
Slaked lime has a proper pH value when it enters the soil.
Look how beautiful the test paper is.
There's a smile in your eyes
The second edition is an overview of the topic, which is also very funny ~ ~ ~
Remember to add zeolite during distillation, otherwise something will happen.
My brother tried it himself and almost died of fright.
I couldn't control the boiling of the solution that time.
Mercury and reagents are sprayed everywhere.
You pour sulfuric acid into it, and I'll watch it outside.
Suddenly, you become soft and hold it in your hand.
Your soul is moving away
Go where I can't go
The sky is blue, and you will faint when it rains.
Smoke rises from the seven orifices, and the soul floats in Wan Li.
Although the sulfuric acid concentration is relatively low this time
Nor can it be used to decorate the body.
Blue face, sweaty, dragged into the water.
Flushing with plenty of water should be no problem.
If you are not at ease, get some baking soda.
Pay attention next time.
There are instruments available in the chemistry building. You're welcome.
If the laboratory has reagents, it will be criticized.
Coke, orange juice, sprite teacher disagreed.
Of course, you can sneak it in
Use volatile reagents in fume hoods.
And your breath of life is hard to last.
You seem to see God.
It's like being struck by lightning under a tree.
There is a thunderstorm on your face. The teacher is waiting for you.
I forgot to wash the desktop and didn't clean it.
The mercury in the broken thermometer under the table.
Do you want to send us to God?
The instruments in the drawer should be placed neatly.
The reagents in the laboratory are all in place.
Remember to be careful when using toxic reagents.
Don't get yourself killed.
The sky is blue, and you will faint when it rains.
Smoke rises from the seven orifices, and the soul floats in Wan Li.
Although the sulfuric acid concentration is relatively low this time
Nor can it be used to decorate the body.
Blue face, sweaty, dragged into the water.
Flushing with plenty of water should be no problem.
If you are not at ease, get some baking soda.
Pay attention next time.
The following is the mathematical version of mathematics, which sets the tone of Jiangnan.
Cut it here and turn it into a string.
Miss sticking to the triangle
People line up here.
Watching us struggle with math
It's fate to have you around.
Fate is written on the supplementary questions.
The topic is Jane in a million.
When I finish, I will be buried on this day.
Cut the rope. Cut the rope.
Every day, every year, every day.
Look at your face deeply
Tangent and cotangent
Triangles and functional surfaces
We don't know how to press the calculator.
I thought the answer would appear in the next second.
The result is to stare at decimals.
Press it again and again in the hope that God will open his eyes.
We don't know how to write it again.
I thought the teacher said there was no need to write this question.
Walking hurts just as much.
I didn't understand until I fell hundreds of times and died.
This is the version of love in BC.
Euclid left the original geometry.
Copy it on white parchment
It has been more than 2300 years now.
Apolloni was born in Paga.
Staring at the eternal conic curve
Diophantine is quietly admiring the solution of indefinite equation.
Who discovered the discrete convergence of differential series?
I like that you keep approaching my limit.
Graduated from Trinity College, Cambridge University
I made a wish in the name of Newton.
Missing propagation like Fourier series.
When there is only topological language left in the space.
Mapping into immortal poems.
My love for you was written in BC.
Buried in Cantor's collection
Transcend forever with transcendental numbers.
Endless infinity
It all started again.
If you want to liven up the atmosphere, you must use this ~ ~ ~
The effect is great. 1! ! !
