资源描述

1、19.3 化学能的利用小 试 身 手1基础题从环境保护的角度考虑,下列燃料中最理想的是( )A氢气 B天然气 C酒精 D汽油2基础题“绿色能源”是指使用时不产生有害排放物(如一氧化碳、二氧化硫等),对空气不造成污染或污染很少的能源。下列能源中属于“绿色能源”的是( )A煤 B汽油 C柴油 D太阳能3基础题人类社会的发展离不开能源。下列说法中你认为正确的是( )A开采海底石油是为了开发新的能源B氢氧燃料电池是一种将化学能转化为电能的装置C人类生存所需要的能量都是通过化学反应获得的D氢能是未来最理想的能源,主要是因为它的热值高4基础题人们的生产和生活离不开能源。(1)目前,人们使用的燃料大多来自化

2、石燃料,如 、石油、天然气等。(2)开发和利用新能源是解决能源问题的重要途径。下列利用了新能源的是 (填字母)。2直 击 中 考5桂林中考 下列能源中,属于可再生能源的是( )A天然气 B太阳能C石油 D煤6台州中考 下列事例中,不是通过化学反应提供能量的是( )7黄冈中考 能源问题是当今世界三大问题之一。下列有关能源的叙述中不正确的是( )A乙醇汽油中添加的乙醇属于可再生能源B人类通过化石燃料获得能量的过程是物理变化C将煤球制成“蜂窝煤”是为了增大与空气的接触面积,使其燃烧更充分D我国南海海底储藏了大量“可燃冰” ,它将成为替代化石燃料的新能源3详解详析1 A2 D ,解析)煤、汽油和柴油燃烧会产生二氧化硫、二氧化氮等气体,不完全燃烧还会产生一氧化碳等物质,不属于“绿色能源” ;太阳能不会产生任何污染物,属于“绿色能源” 。3 B4 (1)煤 (2)AB5 B 6 B7 B ,解析)乙醇可通过粮食发酵制得,属于可再生能源;化石燃料的燃烧生成大量二氧化碳和水等物质,同时释放出能量,属于化学变化;促进燃烧的方法有增大氧气的浓度,增大可燃物与氧气的接触面积,将煤球制成“蜂窝煤”是为了增大可燃物与空气的接触面积,使其燃烧更充分;“可燃冰”储量大,燃烧产物是水和二氧化碳,不污染空气,是替代化石燃料的新能源。
