Most people need to work.If someone loses his job,he may be nervous and wants to find a new job as fast as possible.And even some people give up his spare time because of working.But have you ever thought this question:why should we workuff1f
In my opionion,the basic reason is that we need to work to make a living.If we work, we can get award—money,which is necessary for us to live. So it is an important way to earn money for most people.
But if we only work for money ,our lives will become boring and hopeless.Working also provide us a way to realize our dreams.For exampleuff0cjust like Ma Yun,who is a famous businessman,worked hard to earn much money to support his business—online shopping.He had been a teacher,a translater and so on.And finally he made a challenge in Internet with the money that he earnd through his hard work.With his talent and effort ,he succeeded.So working is a way for us to get close to our dream and let it come true.
Whatu2019s more,our working has a great effect on our society,which promotes our society to develop.Our society needs teachers,doctors,drivers,cooku2026u2026Only with all the labor force can our society run healthily.Maybe you might feel that your work is tiny,but it can make differences for our society.
The last but no least,work can inprove our feelings of happiness.Recently,there is a concerned word on the internet saying “what makes us feel delighted is that you have something to struggle for and look forward to.”Though working ,not only can we get the reword for living ,but also can we enrich our lives.Being busy and do the meaningful job are the good ways to be satisfied to the world.
So working is a hard but meaningful thing in our lives.Working hard is not only good for ourselves but also our society.Work hard,please!

“makemoney”和“earnmoney”这两词组都有“挣钱”的意思。但两者之间却有轻微的区别。“earnmoney”较为强调用劳力、脑筋、知识、透过一段时间的劳动、提供服务、等获取相对比较合理的报酬。时间性可能会比较长。“makemoney”比较多用於买卖交易、灵活变通、等不经常性活动,有时候付出与收获不成比例。时间性方面有时可能只是一单交易而矣。2023-07-06 13:57:541

Make money and Earn money 的英语作文
Money is regarded by some people as the most importent thing in life. It is even regarded as the symbol of wealth and social position. For example, with plenty of money a man can do whatever he wants to. He can afford expensive cars and luxurious houses, and he can travel around the world and visit as many interesting places as he wants to. In their eyes, money is everything in life.In my opinion, money can both benefit people and do harm to them. On the one hand, we can"t deny that money is useful. We need money to buy food, buy a house or pay our education cost. Money can make us live more comfortably. For example, with more money, we can help others and take part in more social activities and receive a good education, thus increasing our knowledge and developing our skills. On the other hand, some people try to get money by dishonest means, for example, they often cheat and gemble, even rob and kill people. Sooner or later, they will be punished by the law. Money can bring them nothing but misery.In addition, money can not buy everything, For instance, no matter how much money one hast he can not buy good health, happiness or friendship, Although money is useful in many ways, there are still a lot of things that money can"t buy in the world. In addition, money can also do harm to us. If a person really thinks of money as everything and pays his attention only to money, he will lose his friends, or even the care and warmth from his family. Thus, it brings him only loneliness.2023-07-06 13:59:011

Na2CO3的物理性质
稳定性较强,但高温下也可分解,生成氧化钠和二氧化碳:长期暴露在空气中能吸收空气中的水分及二氧化碳,生成碳酸氢钠,并结成硬块:碳酸钠的结晶水合物石碱(Nau2082COu2083·10Hu2082O)在干燥的空气中易风化: 以盐酸为例。当盐酸足量时,生成氯化钠和碳酸,不稳定的碳酸立刻分解成二氧化碳和水。这个反应可以用来制备二氧化碳:总的化学方程式是:Nau2082COu2083+2HCl=2NaCl+Hu2082O+COu2082↑离子反应为Na2CO3+2H+=H2O+CO2+2Na+当盐酸少量时发生如下反应:碳酸钠与其他种类的酸也能发生类似的反应。Na2CO3+HCl=NaCl+NaHCO3 初中一般要求掌握有关碳酸钠的俗称(纯碱、苏打),主要用途,化学式以及一些常用反应如:要特别注意碳酸钠虽然俗名纯碱但其实是一种盐。 高中则要求掌握与NaHCOu2083在性质(溶解性、热稳定性、碱性强弱、与酸的反应速率等)用途等方面的区别以及两者的鉴定方法等。其中以Nau2082COu2083为代表的强碱弱酸盐的电离和水解的概念理解、电离和水解平衡的计算尤为重要。2023-07-06 14:02:191

na2co3是酸性还是碱性
Na2CO3是碳酸钠,碳酸钠的水溶液呈碱性,且有一定的腐蚀性,能与酸发生复分解反应,也能与一些钙盐、钡盐发生复分解反应。溶液显碱性,可使酚酞变红。碳酸钠是一种重要的无机化工原料,主要用于平板玻璃、玻璃制品和陶瓷釉的生产。还广泛用于生活洗涤、酸类中和以及食品加工等。 碳酸钠用途 碳酸钠是重要的化工原料之一,广泛应用于轻工日化、建材、化学工业、食品工业、冶金、纺织、石油、国防、医药等领域,用作制造其他化学品的原料、清洗剂、洗涤剂,也用于照相术和分析领域。其次是冶金、纺织、石油、国防、医药及其它工业。玻璃工业是纯碱的最大消费部门,每吨玻璃消耗纯碱0.2吨。在工业用纯碱中,主要是轻工、建材、化学工业,约占2/3,其次是冶金、纺织、石油、国防、医药及其他工业。 碳酸钠危害 该品具有弱刺激性和弱腐蚀性。直接接触可引起皮肤和眼灼伤。生产中吸入其粉尘和烟雾可引起呼吸道刺激和结膜炎,还可有鼻粘膜溃疡、萎缩及鼻中隔穿孔。长时间接触该品溶液可发生湿疹、皮炎、鸡眼状溃疡和皮肤松弛。接触该品的作业工人呼吸器官疾病发病率升高。误服可造成消化道灼伤、粘膜糜烂、出血和休克。2023-07-06 14:00:271
