    【41~50题答案】


    In the early 1600s, British sailors who were traveling to Indonesia began to develop a taste for ketchup. Their food on ships was boring, and ketchup made it taste better. Before long, they brought lots of ketchup home. But it was expensive, so the British started trying to make their own. A London cookbook from 1742 had a ketchup recipe (配方) with beer, fish, mushrooms, and spices.
    It was in the mid-1800s that the British started using tomatoes in ketchup. This was different from the fishy ketchup. Since tomatoes went bad fast, the company, Heinz, began to use vinegar (醋) in ketchup to make sure it could be stored for a long time.
    In the late 1800s, ketchup production and popularity began to rise in America. So, the makers in America increased ketchup production, creating recipes to satisfy Americans’ taste. It was a bit sweeter and thicker than British ketchup. By around 1910, ketchup began to look like the ketchup we put on McDonald’s fries today.
    However, there are also some differences between the ketchup of 1910 and today. In today’s ketchup, corn syrup (玉米糖浆) is used, not sugar. What’s more, to meet people’s needs for a healthy lifestyle, some companies also make healthier ones without sugar.
    From a fishy sauce in ancient Asia to a “goes-great-with-everything” sauce, ketchup has a long history full of changes.
    34．Who made the first ketchup
    35．Why did British sailors like ketchup

    6．已知、、和均有还原性，它们在酸性溶液中还原性的强弱顺序为Fe2＋A． B．
    C． D．
    7．为探究碳酸钠、碳酸氢钠与稀盐酸的反应，某小组同学做了如下实验。下列说法错误的是（ ）
    实验1：
    实验2：
    A．等物质的量浓度溶液的碱性：


    3.B　解析 该反应是放热反应,故反应物的总能量大于生成物的总能量,A项错误;恒温、恒压条件下,充入He,容器容积增大,平衡向逆反应方向移动,B项正确;在恒温、恒容条件下进行反应,气体的密度始终不变,不能说明达到平衡,C项错误;升高温度平衡逆向移动,甲烷的产率会降低,D项错误。
    4.C　解析 温度升高,氨的平衡转化率增大,2NH33H2+N2平衡正向移动,ΔH>0,A项错误;氢气和氮气的物质的量之比始终为3∶1,不能说明反应到达平衡状态,B项错误;2NH3(g)3H2(g)+N2(g)为气体分子数增大的反应,增大压强,平衡逆向移动,氨的平衡转化率减小,因此p15.C　解析 设转化的的物质的量为x mol,可列出三段式:
    　　 　(g) + 2H2(g) (g)
    初始/mol 1 2 0
    转化/mol x 2x x
    平衡/mol 1-x 2-2x x
