    In the world of finance, investment is a crucial concept. It involves putting money into various assets such as stocks, bonds, or real estate with the hope of making a profit.
    Stocks represent ownership in a company. When you buy a stock, you become a part - owner of that company. The value of a stock can fluctuate based on many factors, like the company's performance, economic conditions, and industry trends. Bonds, on the other hand, are a form of debt. When you buy a bond, you are lending money to an entity, usually a government or a corporation. In return, you receive interest payments over a period of time.
    Real estate investment can be in the form of buying a house, an apartment building, or land. The value of real estate can increase over time, and it can also generate income through rent.
    However, investment also comes with risks. The value of assets can decline, and you may lose your money. It's important to do thorough research and understand the market before investing.

    1、包头市2025届高三下学期第二次模拟考试(白黑黑黑白白黑黑)数学答案


    【答案】C
    【3题答案】
    【答案】B
    【4题答案】
    【答案】D
    【5题答案】
    【答案】A


    （3）实验室制取二氧化碳气体为固液常温型反应，发生装置可选B或C，装置C可以通过弹簧夹的打开和关闭控制固体和液体的接触和分离，进而控制反应的发生和停止，则为了随时控制反应的发生和停止，发生装置应选用C；故填:C
    （4）氢气的密度比空气小，用D装置收集 则气体应从导管c端通入；故填:c
    （5）实验室制取二氧化碳常用大理石或石灰石和稀盐酸反应制，取氧气可以用过氧化氢溶液和二氧化锰，这两个反应都是固体和液体在常温下进行的，因此可以使用相同的发生装置；二氧化碳密度大于空气且能溶于水，收集二氧化碳通常使用向上排空气法，氧气密度大于空气且不易溶于水，收集氧气可以使用向上排空气法或排水法，实验室制取 和 均可使用的气体发生和收集装置是AC。故故填: AC;
    （6）如图G所示，从塑料瓶上的小孔通入 一段时间后，湿润紫色石蕊试纸变红，使其变红的物质是水和二氧化碳反应生成的碳酸，故填: 湿润
    （7）如图H所示，在另一个去盖塑料瓶上打2个孔，在塑料瓶外点燃一支蜡烛，火焰与低孔持平。通入CO ，观察到蜡烛熄灭，说明二氧化碳具有的化学性质是不能燃烧，不支持燃烧。故填:不能燃烧，不支持燃烧。
    （8）解：（1）由表中数据可知，第一次加入20g稀硫酸，参加反应的锌的质量为：30g-26.75g=3.25g,第三次加入20g稀硫酸，参加反应的锌的总质量为30g-20.25g=9.75g=3.25g×3，说明每加入20g稀硫酸，第四次参加反应的锌的质量为3.25g,第五次加入20g稀硫酸，参加反应的锌的质量为0，说明已完全反应 ，剩下就是铜，故填：17g
    （2）解：设锌和稀硫酸反应生成生成氢气的质量为x。
