Nowadays, we still see Jacobsen’s designs around us. When you look at the chair design, we can see his chair looks like a simple, neat design. So maybe he liked simple and neat things. Actually, that’s right. He did. For example, he painted his room white because he didn’t like all the flowers on the wallpaper he had. And as an adult, he worked hard to make his designs perfect. But even though he worked hard, Jacobsen liked to joke and do funny things. For instance, he once wore a melon for a hat when someone dared him to. He also liked working on his own projects in his free time and found painting to be relaxing. These days, Jacobsen is famous for his modern, simple designs. His work showed that he thought about the purpose that his designs would serve for people.

3、[全国名校大联考]2025~2026学年高三第一次联考(月考)试卷生物学学CS试题

(1)①K与水反应比Na与水反应剧烈,且有气泡生成　②>
(2)3NH3·H2O+Al3+ Al(OH)3↓+3N
(3)①溶液呈紫红色　②16H++10Cl-+2Mn 2Mn2++5Cl2↑+8H2O　③乙
(4)BD
解析　(1)①根据前两组实验现象,可预测第3组实验现象为K与水反应比Na与水反应剧烈,且有气泡生成。②根据Rb、K两元素在周期表中的位置可知金属性:Rb>K,则最高价氧化物对应水化物RbOH的碱性强于KOH。(2)可溶性铝盐电离出的Al3+能与NH3·H2O反应生成Al(OH)3,其离子方程式为3NH3·H2O+Al3+ Al(OH)3↓+3N。(3)①反应生成碘单质,溶液呈紫红色。②甲方案中KMnO4与浓盐酸反应生成Cl2,其离子方程式为16H++10Cl-+2Mn 2Mn2++5Cl2↑+8H2O。③甲方案中,可能是Cl2与I-反应生成I2,使淀粉-KI试纸变蓝,故该实验不能证明非金属性:Cl>Br>I;乙方案装置A中少量Cl2与NaBr反应生成Br2,打开分液漏斗活塞,Br2与KI反应生成I2,可证明非金属性:Cl>Br>I。(4)卤素单质的熔点属于物理性质,不能用于元素非金属性强弱比较,A错误;根据气态氢化物的稳定性,可比较元素非金属性,B正确;卤化银固体的颜色,属于物理性质,不能用于元素非金属性强弱比较,C错误;Cl-、Br-、I-的还原性逐渐增强,说明相应元素非金属性逐渐减弱,D正确。
18.答案　(除标注外,每空2分)
(1)第三周期第ⅥA族(1分)

故答案为：B。
【分析】根据离子符号是在元素符号右上角标上所带电荷数，多个离子符号前加系数分析。
3．（2025·辽宁）辽砚主要含碳、氧、硅、钙等元素，其中属于金属元素的是（　　）
A．碳 B．氧 C．硅 D．钙
【答案】D
【知识点】元素的简单分类
【解析】【解答】A、碳名称带“石”为非金属元素，不符合题意；
