1.

如图,某人将一块正五边形玻璃打碎成四块,现要到玻璃店配一块完全一样的玻璃,那么最省事的方法是带{#blank#}1{#/blank#} 块.

2.

日常生活中,燃烧现象屡见不鲜.小明设计了如下实验方案探究燃烧的条件:

Ⅰ、设计并进行实验(如图).

(1)用镊子分别夹取一根小木条和一块小石子,在酒精灯上点燃.

(2)用镊子分别夹取一个蘸有水、一个没蘸水的小棉花团,放到酒精灯火焰上片刻.

(3)分别点燃两支小蜡烛,将其中一支蜡烛用玻璃杯罩住.

Ⅱ、分析实验.

请帮小明将未完成的实验报告填写完整:

{#blank#}4{#/blank#}

Ⅲ、得出结论.

燃烧需要三个条件:①需可然物;②{#blank#}5{#/blank#};③{#blank#}6{#/blank#}

3.

如图装置可用于探究可燃物的燃烧条件(夹持仪器略去)

实验操作步骤及现象如下:

第1步:检查装置气密性;

第2步:如图所示加入药品;

第3步:向B试管冷水中的白磷通氧气,白磷不燃烧;

第4步:待A试管中不再产生氧气时,再向B试管中加入90℃的热水,白磷不燃烧

第5步:向B试管热水中的白磷通氧气,白磷燃烧,产生白烟.

①写出A试管中发生反应的化学方程式 {#blank#}1{#/blank#} ;

②对比上述操作步骤可得出可燃物的燃烧条件.

对比的操作步骤

得出的结论

第{#blank#}2{#/blank#} 步和第5步

可燃物燃烧温度需要达到着火点

第{#blank#}3{#/blank#} 步和第5步

{#blank#}4{#/blank#}
