第五單元 化學(xué)方程式
課題1 質(zhì)量守恒定律
教學(xué)目標(biāo)：
1、 識(shí)記：質(zhì)量守衡定律
2、 理解：從微觀角度認(rèn)識(shí)質(zhì)量守衡定律
3：能用微粒的觀點(diǎn)說明質(zhì)量守恒的本質(zhì)原因，能用質(zhì)量守恒定律解釋常見化學(xué)反應(yīng)中質(zhì)量關(guān)系。認(rèn)識(shí)定量研究對(duì)化學(xué)科學(xué)發(fā)展的意義。
4：通過具體化學(xué)反應(yīng)分析，使學(xué)生理解化學(xué)方程式的涵義。
重點(diǎn)：質(zhì)量守恒定律的涵義及應(yīng)用，正確書寫化學(xué)方程式。
難點(diǎn)：質(zhì)量守恒定律的理解及應(yīng)用，正確書寫化學(xué)方程式。
教學(xué)過程：
本單元內(nèi)容分為兩部分，第一部分“質(zhì)量守恒定律”從量的方面去研究化學(xué)反應(yīng)的客觀規(guī)律，為化學(xué)方程式的教學(xué)作好理論準(zhǔn)備，這是學(xué)好本單元內(nèi)容的基礎(chǔ)。第二部分“化學(xué)方程式”講了書寫化學(xué)方程式的原則、方法和步驟，說明化學(xué)方程式表示的意義，這是本單元的中心。
一：質(zhì)量守定律
展示化學(xué)反應(yīng)實(shí)例為學(xué)生創(chuàng)設(shè)情境。引出化學(xué)反應(yīng)前后物質(zhì)的質(zhì)量總和有何變化。
教師引導(dǎo)學(xué)生回答怎樣設(shè)計(jì)實(shí)驗(yàn)來檢驗(yàn)自己的猜想。
教師演示實(shí)驗(yàn)：白磷燃燒設(shè)疑：（1）觀察到哪些現(xiàn)象？
（2）分析結(jié)果思考：反應(yīng)中玻璃管上端沒有系小氣球，將會(huì)出現(xiàn)什么結(jié)果？
指導(dǎo)學(xué)生動(dòng)手實(shí)驗(yàn)，并設(shè)疑：反應(yīng)前后物質(zhì)總質(zhì)量有何關(guān)系？通過實(shí)驗(yàn)分析得出結(jié)論。（1）觀察到哪些現(xiàn)象？
（2）記錄反應(yīng)前后物質(zhì)總質(zhì)量；
（3）分析結(jié)果。指導(dǎo)學(xué)生分析討論：以碳在氧氣中燃燒生成二氧化碳為例，從化學(xué)反應(yīng)中分子、原子的變化情況說明化學(xué)反應(yīng)必定符合質(zhì)量守恒定律。教師通過微觀模擬講解化學(xué)反應(yīng)前后原子的種類、數(shù)目、都沒有變化。
分組學(xué)生實(shí)驗(yàn)：
1、鐵釘與硫酸銅溶液反應(yīng)；
2、蠟燭燃燒
根據(jù)實(shí)驗(yàn)結(jié)果分析化學(xué)反應(yīng)前后物質(zhì)的質(zhì)量總和相等
講解化學(xué)方程式的書寫方法及化學(xué)議程式所表明的涵義指導(dǎo)學(xué)生討論：下列反應(yīng)的化學(xué)方程式能提供給你哪些信
根據(jù)實(shí)驗(yàn)結(jié)果分析化學(xué)反應(yīng)前后物質(zhì)的質(zhì)量總和相等
實(shí)驗(yàn)方案
實(shí)驗(yàn)方案1
實(shí)驗(yàn)方案2
實(shí)驗(yàn)
反應(yīng)前總質(zhì)量
反應(yīng)后總質(zhì)量
分析
學(xué)生討論得出結(jié)論：化學(xué)反應(yīng)前后原子的種類沒有改變，數(shù)目沒有增減，質(zhì)量也沒有改變。
教材在從實(shí)驗(yàn)的結(jié)果歸納出質(zhì)量守恒定律后，接著就提出“為什么物質(zhì)在發(fā)生化學(xué)反應(yīng)前后，各物質(zhì)的質(zhì)量總和相等呢？”提出這個(gè)問題的目的，在于要引導(dǎo)學(xué)生從化學(xué)反應(yīng)的實(shí)質(zhì)上去認(rèn)識(shí)質(zhì)量守恒定律。在化學(xué)反應(yīng)中，只是由于發(fā)生了原子間的重新組合，才使反應(yīng)物變成生成物，但在這一變化中，原子的種類和個(gè)數(shù)并沒有發(fā)生變化，原子的質(zhì)量也沒有發(fā)生變化，所以，反應(yīng)前和反應(yīng)后各物質(zhì)的質(zhì)量總和必然相等。應(yīng)該注意，對(duì)質(zhì)量守恒定律的本質(zhì)分析，要明確落到化學(xué)反應(yīng)前后原子的種類和個(gè)數(shù)保持不變這一關(guān)鍵點(diǎn)上，這不僅有利于理解質(zhì)量守恒定律的本質(zhì)，而且為學(xué)習(xí)化學(xué)方程式準(zhǔn)備了基礎(chǔ)知識(shí)
【小結(jié)板書】參加化學(xué)反應(yīng)的各物質(zhì)的質(zhì)量總和等于反應(yīng)后生成的各物質(zhì)的質(zhì)量總和，這個(gè)規(guī)律叫做質(zhì)量守恒定律。（此定律為重要概念可讓學(xué)生在1～2min內(nèi)熟練背誦下來。）
〔設(shè)疑〕為什么物質(zhì)在發(fā)生化學(xué)反應(yīng)前后質(zhì)量總是相等呢？
〔閱讀〕見教材有關(guān)內(nèi)容，學(xué)生閱讀討論后回答。
〔板書〕在一切化學(xué)反應(yīng)中，反應(yīng)前后原子的種類沒有改變，原子的數(shù)目沒有增減．原子的質(zhì)量也沒有變比。所以，化學(xué)反應(yīng)前后各物質(zhì)的質(zhì)量總和必然相等。
〔鞏固練習(xí)〕1．試解釋鎂條在空氣中燃燒后，固體的質(zhì)量增加了。
2．蠟燭燃燒后質(zhì)量是否變化？是否遵守質(zhì)量守恒定律？
二：化學(xué)方程式
化學(xué)方程式是初中化學(xué)入門的三種重要化學(xué)用語(yǔ)，掌握了它們才有可能學(xué)好化學(xué)，其重要性可想而知。學(xué)生已經(jīng)學(xué)習(xí)了元素符號(hào)、化學(xué)式、化學(xué)反應(yīng)的實(shí)質(zhì)，知道了一些化學(xué)反應(yīng)和它們的文字表達(dá)式，結(jié)合剛學(xué)習(xí)了質(zhì)量守恒定律，已經(jīng)完全具備了學(xué)習(xí)化學(xué)方程式的基礎(chǔ)
教材根據(jù)質(zhì)量守恒定律，導(dǎo)出了化學(xué)方程式的概念，即用物質(zhì)的化學(xué)式表示化學(xué)反應(yīng)的式子叫化學(xué)方程式。通過木炭在氧氣中燃燒這個(gè)實(shí)例，用簡(jiǎn)煉的文字準(zhǔn)確敘述了化學(xué)方程式的意義：(1)表示了化學(xué)反應(yīng)物和生成物。(2)表明了該化學(xué)反應(yīng)進(jìn)行的條件。(3)表示了各物質(zhì)之間的質(zhì)量關(guān)系，即各物質(zhì)之間的質(zhì)量比。
【復(fù)習(xí)提問】1．什么是質(zhì)量守恒定律？2．為什么在化學(xué)反應(yīng)前后，各物質(zhì)的質(zhì)量總和必然是相等的呢？（用原子、分子的觀點(diǎn)說明。）
〔引言〕我們已經(jīng)知道質(zhì)量守恒定律，那么在化學(xué)上有沒有一種式子，既能表示出反應(yīng)物和生成物是什么，又能反映出遵循質(zhì)量守恒定律呢？回答是肯定的，這就是化學(xué)方程式。
板書〕化學(xué)方程式
化學(xué)方程式：用化學(xué)式來表示化學(xué)反應(yīng)的式子。
例如：木炭在氧氣中充分燃燒的化學(xué)方程式為：C + O2
CO2
12∶ 16×2 ∶ 12+16×2
（指出化學(xué)方程式質(zhì)和量的意義。） 12 ∶ 32 ∶ 44
化學(xué)方程式能客觀地反映出化學(xué)反應(yīng)中“質(zhì)”和“量”的變化及關(guān)系。所以化學(xué)方程式的讀法不同于數(shù)學(xué)方程式。化學(xué)方程式中的“+”號(hào)應(yīng)讀成“和”，不能讀成“加”；反應(yīng)物和生成物中間的“==”號(hào)，應(yīng)讀成“生成”，不能讀成“等于”。
H2 + CuO 加熱 Cu + H2O
Mg+CuO加熱MgO+Cu
化學(xué)方程式可讀出質(zhì)的變化，也可讀出量的變化。每個(gè)方程式都有三種讀法
現(xiàn)以2H2O
2H2↑+O2↑為例說明。
（一）物質(zhì)讀法
上式讀作“在通電的條件下，水分解生成氫氣和氧氣”，這種讀法說明了化學(xué)反應(yīng)中物質(zhì)的變化。
（二）粒子讀法
上式讀作“在通電條件下，每2個(gè)水分子分解生成2個(gè)氫分子和1個(gè)氧分子”。這種讀法揭示了化學(xué)反應(yīng)中結(jié)構(gòu)微粒的變化，并反映出微粒個(gè)數(shù)的比例關(guān)系。
（三）數(shù)量讀法
上式讀作“通電時(shí)，36份質(zhì)量的水分解生成4份質(zhì)量的氫氣和32份質(zhì)量的氧氣”，這種讀法表明了化學(xué)反應(yīng)中物質(zhì)的數(shù)量關(guān)系。
化學(xué)方程式跟數(shù)學(xué)方程有何不同？
數(shù)學(xué)上的方程式，僅是表示等號(hào)兩邊的數(shù)目相等。等號(hào)兩邊各項(xiàng)可以移項(xiàng)或倒寫。而化學(xué)方程式可以：
(l)表示反應(yīng)物是什么，生成物是什么。
(2)表示各種反應(yīng)物的總質(zhì)量等于各種生成物的總質(zhì)量（質(zhì)量守恒）。
(3)表示反應(yīng)物與生成物的原子、分子個(gè)數(shù)比。
(4)表示反應(yīng)物和生成物的質(zhì)量比。 化學(xué)方程式是不能倒寫和移項(xiàng)的，如，不能將3Fe+2O2Fe3O4寫成 Fe3O43Fe+2O2，也不能寫成3FeFe3O4－2O2。
至于化學(xué)方程式中的“+”和“=”號(hào)雖與數(shù)學(xué)中的“+”和“=”號(hào)在形式上一樣，但其意義卻不相同�；瘜W(xué)方程式中的“+”，在讀時(shí)不讀“加”而是讀“和”�；瘜W(xué)方程式中的“等號(hào)”表示“生成”的意思，同時(shí)表明在化學(xué)反應(yīng)前后有兩個(gè)不變：原子種類不變；每種原子的總個(gè)數(shù)也不變�！�=”讀作“反應(yīng)生成”而不能讀“等于”。
課題2 如何正確書寫化學(xué)方程式
教學(xué)目標(biāo)：
1：理解化學(xué)方程式書寫原則
2：學(xué)會(huì)化學(xué)方程式的簡(jiǎn)單配平
重點(diǎn)：重點(diǎn)是正確書寫化學(xué)方程式
難點(diǎn)：難點(diǎn)是化學(xué)方程式的配平方法
教學(xué)過程：
化學(xué)方程式的書寫是本單元的一個(gè)重點(diǎn)內(nèi)容。在講解書寫化學(xué)方程式要遵守兩個(gè)原則時(shí)，教材強(qiáng)調(diào)指出：不能隨意臆造事實(shí)上不存在的物質(zhì)和化學(xué)反應(yīng)，不能任意編造物質(zhì)的化學(xué)式。教材以磷在空氣中燃燒生成五氧化二磷的反應(yīng)為例，說明書寫化學(xué)方程式的三個(gè)步驟：
（1）依據(jù)實(shí)驗(yàn)事實(shí)，把反應(yīng)物的化學(xué)式寫在左邊，生成物的化學(xué)式寫在右邊，反應(yīng)物與生成物之間用一條短線相連
(2)：根據(jù)質(zhì)量守恒定律，在反應(yīng)物、生成物的化學(xué)式前配上適當(dāng)?shù)南禂?shù)，使式子左、右兩邊的每一種元素的原子總數(shù)相等，這個(gè)過程叫化學(xué)方程式的配平。
(3)：要在化學(xué)方程式中注明反應(yīng)發(fā)生的基本條件，用“↓”表示生成物中的沉淀，用“↑”表示生成物中的氣體。在上述三個(gè)步驟中，以化學(xué)方程式的配平最為關(guān)鍵，
教材始終以質(zhì)量守恒定律作為理論指導(dǎo)，化學(xué)方程配平，就是要使完成的化學(xué)方程式符合質(zhì)量守恒定律，而且在最后還要求教師組織學(xué)生討論“為什么說質(zhì)量守恒定律是書寫化學(xué)方程式的理論基礎(chǔ)？”來加以強(qiáng)化。
此外，教材還介紹了用最小公倍數(shù)法配平化學(xué)方程式。最小公倍數(shù)法是一種比較簡(jiǎn)單和常用的配平方法，應(yīng)當(dāng)在課堂上適當(dāng)組織練習(xí)，使學(xué)生初步學(xué)會(huì)這種配平方法。本單元教材的特點(diǎn)是：通過對(duì)多種化學(xué)實(shí)驗(yàn)的觀察和思考，得出質(zhì)量守恒定律，再把質(zhì)量守恒定律運(yùn)用于化學(xué)反應(yīng)，配平化學(xué)方程式，并初步涉及到定量研究化學(xué)反應(yīng)的科學(xué)方法
以磷在空氣中燃燒生成五氧化二磷的反應(yīng)為例，說明書寫化學(xué)方程式的具體步驟。
〔板書〕1．根據(jù)實(shí)驗(yàn)事實(shí)寫出反應(yīng)物及生成物的化學(xué)式 P+O2─P2O5
2．配平化學(xué)方程式 用最小公倍數(shù)法確定系數(shù)。（根據(jù)是質(zhì)量守恒守律）。把短線改等號(hào)。
4P+5O2===2P2O5
3．注明反應(yīng)發(fā)生的條件4P+5O2點(diǎn)燃2P2O5
（介紹“△”’“↑”“↓”等符號(hào)表示的意義，及“↑”“↓”符號(hào)的使用范圍）。
〔講解〕反應(yīng)條件常見的有：點(diǎn)燃、加熱（△）、高溫、催化劑等。
“↑”“↓”號(hào)的使用范圍：在反應(yīng)物中無氣態(tài)物質(zhì)參加反應(yīng)，如果生成物中有氣體，則在氣體物質(zhì)的化學(xué)式右邊要注“↑”號(hào)；在溶液中進(jìn)行的化學(xué)反應(yīng)，反應(yīng)物無難溶性物質(zhì)參加反應(yīng)，如果生成物中有固體難溶性物質(zhì)生成，在固體物質(zhì)的化學(xué)式右邊要注“↓”號(hào)。（強(qiáng)調(diào)要防止隨意亂標(biāo)）

“BANG”the door caused a reverberation．“Never set foot in this house again!”shouted father．With tears weiling(涌出)up in my eyes，I rushed out of the hofase and ran along the street．
A young father who held a child in his arlzis walked past rile．I felt as if I saw my childhood from another space：happy and harmonious(和諧)
But now I don’t know whether it is because I have grown up or because Dad is getting old．We are just like two people coming from two different worlds．It feels like there is an iron door between us that can never be opened．
1 wandered the street，without a destination in my n'nnd．My heart was frozen oil this hot summer night．As I walked on there were fewer and fewer people m the streets，until I had only streets to keep me company When I finally reached the high rise apartment block in which I livegt，I saw that the light was still on．
I thought to myself，“Is father waiting for rile．or is he still angry with me?”
In fact，it was nothing．Perhaps，Dad was throwing some of his old stamps．Perhaps he thought they were useless．I never had th,e courage to tell him that I liked collecting stamps．
All the lights were off except father’S
Dad was always 1ike this．Maybe he didn’t know bow to express himself．After shouting at me，he never showed any mercy or regret After an argument he will creep(躡手躡腳)up in my sleep and then tuck rile underneath the covers
This was how he always was．Fie has been a leader for So long that telling everyone else what to do has become his second nature．
The fight was still oil With the key in hand，1 was as nervous as 1 had ever been．At last，I decided to open the door．As soon as I opened the door tears ran down my cheeks．I suddenly realized that the iron door that l had imagined between us did not exist at all Love－it is second to none．

Whenever you send a letter or a postcard，you have to put stamps on the envelope or on the card．When did people first begin to use stamps?Who was the first to think of this idea?
In the early nineteenth century，people did not use stamps．They had to pay postage when they receive letters．They unhappy about this，especially when they pay for a letter which they did not wish to receive at a11．The postage was high at that time，because the post offices had to send many people to cotlem the postage．
RowIand Hill，a schoolnlaster in England，was the first to put forward a proposal to use stamps in the 50s of the nineteenth century．fie thought it would be much easier for people to use stamps to coover postage．They could go to the nearby post office to buy stamps and put them on envelopes before they sent the letters，The post office simply put seals on the stamps so that people could not use the staraps again．In this way，the post office did not need to send postmen to collect postage．It only needed to send fewer postmen to deliver letters．’That was a good idea and the governmern finally accepted it．

What is the beauty standard?
What does beauty really mena ?Everybody had his own ideas on beauty.
Some students think that a good face is a letter of recommemdation. Good appearance often makes a big difference in social communication, sompetition, finding jobs and so on ,Not only can it help you becomemore confident , but also it helps you b eimpresed, Physical beauty is likely to draw much attention,
On the contrary, other students have quite different opinions, They hold the idea that good appearance will be of no value, Inner beauty is more important, A beautiful person is not the one with a good looking , but with a broad and kind heart,
In my opinion,the different ideas on beauty above are both acceptable although the criteria of beauty change with different time, societies, and cultures.
