My fellow students! I am your eastern teacher, the master of quick reading. Today, if we don't mind anything else, we're going to solve a century puzzle that's been so painful to countless students — the memory of chemical equations. Stop being so hard-headed, follow the orient teacher's rhythm, five minutes, and i'm going to let you take the core equations completely and master the bottom of the equation. Focus, let's go
One, dead-headed? That's an anti-human lesson
A lot of students have a big look at "2kclo3 →2kcl + 3o2 ↑" and eat it in one letter, like a hype. And? Forget it, forget it, suffer a lot and blow confidence。
The east teacher struck the blackboard:
Death note is the most efficient way to learn! It consumes your willpower, causes pain, and it does not work. Real memories, like pictures, are printed in the head, fast and hard. How? Three great powers — focus core, stenography code, mind map. Let's split up。
Two, action on! Three core equations in five minutes
We're not greedy. We're going to get through the three most common, most important types of response. And understand them, the other equations are basically, "no soup for medicine."。
Equivalent 1: laboratory oxygen - decomposition of potassium chlorate
Reaction: 2kclo3→2kcl+3o2↑
Step 1: focus core (understanding the nature of the response)
Don't look at it like a bunch of letters. At the heart of it is a substance, potassium chlorate, which, after heating, breaks into two new substances, potassium chloride and oxygen. Mno2 is a catalyst, an “associate” and does not participate in the response, so it remains the same before and after the reaction。
Step 2: sniper coding (image + story memory)
Here's a story for you
"the green (cl)-coloured (kcl3)-coloured (kcl3) shellworm is old, it's too hot (heated), it's sweating, and it's thin, it's turned into a green (cl)-coloured (kcl) shellworm, and it's spitting out three (3) argon (o2) bubble."
How
“green armour iii” → kclo3 (purple chlorate)
Skinny success
"green" → kcl (purple chloride)
"three oxygen bubbles"
Remember? Isn't it 10,000 times more fun than a hard back
Equation 2: metal replacement reaction - "coron iron and sulphurate"
Reaction: fe + cuso4 → cu + feso4
Step 1: focus core (understanding the nature of the response)
It's a “deeping wall foot” reaction. A more lively metal (iron) has replaced less than its metal (copper) from its compound (copper sulphate) and moved in。
Step 2: sniper coding (harmonic + scenario memory)
Here, construct a scene:
"a man of iron (fe) is jumping into a blue pool (cuso4) he had the strength to throw the original owner, cu, out of the pool and turn himself into a green
How
→fe + cuso4
→cu
→ feso4 (softly green)
Look, the color, the phenomenon, the result, remember! This is the power of image memory
Equation 3: moderate reaction of acid and alkalis - "odium hydrochloric acid and hydroxide"
Reaction: hcl+naoh→nacl+h2o
Step 1: focus core (understanding the nature of the response)
This is the process by which “acid” and “alkali” shake hands with the wrong-doer! The combination of acid (h+) and alkali (oh-) produces harmless water (h2o) and salt (nacl)。
Step 2: sniper coding
It's the easiest thing to do
"h (drink) na (girl) oh (girl), na (girl), cl (church) love, resulting in salt water (nacl and h2o) thall."
How
"the girl who drank coke."
"so cute, producing salt water"
Perfect! Even the common name of the generator is connected
Iii. One to three: build your equation memory system
All right, three of them are chestnuts, and now i'll give you a "gang key" that opens all the equation doors
Classification (thinking)
Don't make equations an island! Use a mind map to string them up. For example:
Centre: chemical equations
Branch 1: decomposition reaction (like potassium chlorate for oxygen)
Branch 2: replace reaction (like iron for copper)
Branch 3: resolved reactions (like neutrals)
I'm sorry
So, when you encounter a new equation, you can determine which one it belongs to, and you can immediately apply a similar story model。
Grab a memory anchor:
Each equation has the most unique memory point, possibly:
Colours: cuso4 (blue), feso4 (green), cu (oh)2 (blue)
Status: zirconium (gas), zirconium (deposition)
Reaction conditions: (heating), ignition
Focus on these anchors so that the whole equation can be easily hooked out。
Iv. The final and final approach of the eastern teacher
Children, learning good bottom logic is not about time, but methods and efficiency。
Attention is the foundation of all capabilities. You can't even play games without focus, let alone study。
Memory is not a repetition. It is a connection. Link your strange chemical symbols to images, stories, feelings you know。
Understanding is the father of memory. It takes 30 seconds to figure out why, and then 10 seconds to "remember how."。
From this day on, throw away the crutch. Using the "focus core-stenographic encoding-thinking" three-step method taught you by the eastern teacher to conquer all the knowledge you can't remember
Remember, you don't have bad memory, you just don't have the right way. Okay, it's five minutes. See if your equations are in your head. Use it
- your eastern teacher, read the shorthand. I'll see you next time
