  • 高锰酸钾氧气制取方程式

Q1:高锰酸钾制取氧气化学式

化学方程式为:2KMnO=加热=KMnO+MnO+O↑。高锰酸钾制取氧气的文字表达式:高锰酸钾→(加热)锰酸钾+二氧化锰+氧气。高锰酸钾是一种强氧化剂,为黑紫色、细长的棱形结晶或颗粒,带蓝色的金属光泽,无臭,与某些有机物或易氧化物接触,易发生爆炸。

高锰酸钾的危害:

高锰酸钾有毒,且有一定的腐蚀性。吸入后可引起呼吸道损害。溅落眼睛内,刺激结膜,重者致灼伤。刺激皮肤后呈棕黑色。浓溶液或结晶对皮肤有腐蚀性,对组织有刺激性。

口服后,会严重腐蚀口腔和消化道。出现口内烧灼感、上腹痛、恶心、呕吐、口咽肿胀等。口服剂量大者,口腔粘膜黑染呈棕黑色、肿胀糜烂,胃出血,肝肾损害,剧烈腹痛,呕吐,血便,休克,最后死于循环衰竭,高锰酸钾纯品致死量约为10g。

危险性质:高锰酸钾助燃,具腐蚀性、刺激性,可致人体灼伤。

Q2:高锰酸钾制取氧气,化学表达式

高锰酸钾制取氧气是在加热的条件下,生成锰酸钾、二氧化碳和氧气,化学方程式如下:


高锰酸钾加热分解是常用的抽取氧气的方法,步骤如下:



  1. 查----检查装置的气密性


  2. 装----装药品


  3. 定----把试管固定到铁架台上


  4. 点----点燃酒精灯加热(先预热,注意:一律先让试管均匀受热,否则会因冷热不均炸裂试管)


  5. 收----收集气体(可以使用排水法、向上排空气法)


  6. 离----把导管从水槽中取出(如果使用向上排空气法,此步骤基本不需要,但是最好先取出导管在盖上玻片)


  7. 熄----熄灭酒精灯



Q3:高锰酸钾制取氧气化学式

高锰酸钾制取氧气的化学方程式如下:


2KMnO4=K2MnO4+MnO2+O2↑(条件:加热)

Q4:高锰酸钾制氧气的化学方程式

高锰酸钾制氧气的化学方程式:


2KMnO₄ =△= K₂MnO₄+MnO₂+O₂↑


在高锰酸钾制取氧气的实验中需要加热一段时间才能收集到氧气(主要是活化能的缘故),因此写方程式时“加热”这一反应条件必不可少。


扩展资料


高锰酸钾为黑紫色、细长的棱形结晶或颗粒,带蓝色的金属光泽;无臭。


在化学品生产中,广泛用作为氧化剂,例如用作制糖精,维生素C、异烟肼及安息香酸的氧化剂;在医药上用作防腐剂、消毒剂、除臭剂及解毒剂;在气体净化中,可除去痕量硫、砷、磷、硅烷、硼烷及硫化物;在采矿冶金方面,用于从铜中分离钼,从锌和镉中除杂,以及化合物浮选的氧化剂;还用于作特殊织物、蜡、油脂及树脂的漂白剂,防毒面具的吸附剂,木材及铜的着色剂等。


高锰酸钾具有强氧化性,在实验室中和工业上常用作氧化剂,遇乙醇即分解。在酸性介质中会缓慢分解成二氧化锰、钾盐和氧气。光对这种分解有催化作用,故在实验室里常存放在棕色瓶中。

Q5:高锰酸钾制取氧气化学式 高锰酸钾如何制取氧气

1、化学方程式为:2KMnO=加热=KMnO+MnO+O↑。高锰酸钾制取氧气的文字表达式:高锰酸钾→(加热)锰酸钾+二氧化锰+氧气。

2、高锰酸钾是一种强氧化剂,为黑紫色、细长的棱形结晶或颗粒,带蓝色的金属光泽,无臭,与某些有机物或易氧化物接触,易发生爆炸。

Q6:高锰酸钾氧气制取方程式

高锰酸钾氧气制取方程式:KMnO=△=KMnO+MnO+O↑。氧气,化学式O2。化学式量:32.00,无色无味气体,氧元素最常见的单质形态。熔点-218.4℃,沸点-183℃。不易溶于水,1L水中溶解约30mL氧气。在空气中氧气约占21%。液氧为天蓝色。固氧为蓝色晶体。常温下不是很活泼,与许多物质都不易作用。但在高温下则很活泼,能与多种元素直接化合,这与氧原子的电负性仅次于氟有关。

高锰酸钾(Potassiumpermanganate)为黑紫色、细长的棱形结晶或颗粒,带蓝色的金属光泽;无臭;与某些有机物或易氧化物接触,易发生爆炸,溶于水、碱液,微溶于甲醇、丙酮、硫酸,分子式为KMnO4,分子量为158.03400。熔点为240°C,稳定,但接触易燃材料可能引起火灾。要避免的物质包括还原剂、强酸、有机材料、易燃材料、过氧化物、醇类和化学活性金属。

    案公布Yingluck could be sentenced to as much as 10 years in prison if found guilty of negligence over a costly rice subsidy scheme that helped to bring her to power in an election in 2011新组建"The ginger output of the base can reach nearly 100,000 kg, whose production value is one million yuan ($150,716) as long as appropriate technologies and management skills are used," said Wang资源部He studied at China Three Gorges University and has lived in China for 11 years, during which he fell in love with Lyu Xueqin, a woman from Enshi, Hubei province, who became his wife later定方Kottuvala Abdul Mateed from India helps his Chinese father-in-law to expand their ginger business abroad

    cn]A 31-year-old Indian in Central China's Hubei province cultivates ginger with his Chinese father-in-law at their home village and exports it to countries in Asia, North America and Latin America, Chutian Metropolis Daily reportedThe family's business also received local government's support, which arranged experts from universities to provide guidance and helped them construct a cellar, which is capable of storing 150,000 kg of ginger

    新组建的自然资源部“三定”方案公布

    The couple established a company in South China's Guangdong province to export various agriculture products, including ginger, to countries, such as India, Saudi Arabia, Brazil and United States, through Dubai portThe man, originally from New Delhi, gave himself a Chinese name called Wang Wei, same as one of the most famous poets in Tang Dynasty (618-907)The seeds grew up successfully and they decided to set up a ginger cultivation base spread over 2Last year, Wang together with his father-in-law, Lyu Weiping, brought ginger seeds and cultivation technology to their home village in Hubei after inspecting them in East China's Shandong province

    The two sides will exchange views on bilateral ties, US President Donald Trump's visit to China this year, and major international and regional issues, Lu saidBEIJING - US Secretary of State Rex Tillerson will visit China on Sept30 at the invitation of Chinese Foreign Minister Wang Yi, Chinese Foreign Ministry spokesperson Lu Kang said WednesdayThe training course on the Chinese lion dance is part of the 2017 China Africa Cultures in Focus, an activity held by the Bureau for External Cultural Relations of Chinese Ministry of Culture to strengthen the cultural communication between China and African countries

    They kept practicing from morning until night, trying to master the basic skills of lion dance, routines and instrumental music within a short periodThe cultural center of the Jinpu New Area has undertaken the course for three consecutive years since 2015

    新组建的自然资源部“三定”方案公布

    The cultural center of the Jinpu New Area also arranged some courses for them to know about other traditional Chinese culture such as Chinese calligraphy, seal cutting, folk dance, paper-cutting, and potteryDuring the 35-day training course, they learned from Li Mingxu, the fifth generation successor of the Jinzhou Lion Dance, a provincial intangible cultural heritage that has been passed from generation to generation for more than a century

    Ten students from Nigeria and Zambia learned how to perform Chinese lion dance at the Jinpu New Area in Dalian, Northeast China's Liaoning provinceWhat has it to do with dissolving the lower house now?" said Seiji Maehara, leader of the largest opposition Democratic PartyTOKYO - Japanese Prime Minister Shinzo Abe announced at a press conference on Monday that he will dissolve the House of Representatives when it convenes Thursday to pave way for a general election next monthThe prime minister cited the need to seek a fresh mandate to overcome "a national crisis" caused by "the biggest challenge facing Japan, which is the population aging and low birthrate," as well as security challengesAbe has been under fire for his connection with nationalist private school operator Moritomo Gakuen, which purchased a piece of state-owned land in Osaka for only a fraction of the market priceHe said that he would seek mandate from the people for shifting the usage of part of the revenue generated by a consumption tax hike that has been delayed until 2019 from paying debt to welfare policies

    He added that the reason Abe cited for dissolving the lower house is not convincing, and that the prime minister is just trying to avoid further grilling on favoritism scandalsHe also said that he would seek public support for a tougher stance over the Korea Peninsula issue

    He has also been accused of using his influence to make the government choose Kake Educational Institution, run by a close friend of Abe's, to open a new department in a government- designated special economic zoneAbe's decision to call for a snap election, however, has drawn staunch criticism from opposition parties, which argued that there is no reason to dissolve the lower house of parliament before its current term expires in December 2018

    The college, with a transitional campus at Hainan University, will relocate to its permanent campus, which is under construction in Mission Hill in Haikou"Even the teaching building of HAITC is the same as in Arizona State University in order to enhance students sense of belonging," he said

    About one-third of the college's teachers are from Arizona State University and one-third from global recruitment, with others from Hainan University, according to WangLi Jianbao, president of Hainan University,said that HAITC is the first domestic Sino-foreign cooperative tourist institution formally approved by the Ministry of Education in May 2017"Through this partnership, we leverage our two institutions' expertise, resources and passion for community development and public service," Jonathan GS Koppell, dean of ASU College of Public Service and Community Solutions, saidHAITC is an international and innovative joint college established by Hainan University and American top-ranking public research institution, Arizona State University, the first of its kind in China

    A total of 268 students majoring in hotel management, human geography and urban/rural planning and administrative management attended the opening ceremonyHainan University and Arizona State University Joint International Tourism College, which is affiliated with Hainan University, opened its first-ever session in Haikou, capital of China's southern Hainan province, on Monday

    The college is aiming to cultivate management personnel with a global vision and international competitiveness of tourism"This new college is an incredibly exciting and innovative initiative," Koppell said when addressing the opening ceremony on Monday

    The students also will have access to the quality teaching, research resources and electronic library resources with ASU, she addedThat means that the students can enjoy American top university teaching resources without going abroad, said Wang Lin, head of the new college

    With the professional courses taught in English, students will get double degrees, one from Hainan University and another from Arizona State University, if they successfully graduate from the collegeTuition is about 60,000 yuan for each semester, which is much less than that in ASU's US headquarters, while excellent students have the same access to various scholarships4 magnitude earthquake recorded on Saturday near the Democratic People's Republic of Korea's most recent nuclear test site was "natural"The test prompted global condemnation, leading the United Nations Security Council to unanimously adopt new sanctions that include restricting the DPRK's oil shipments

    The report said the analysis of seismic waves and the lack of sound waves clearly showed the quake was not caused by an artificial explosion, citing an unnamed weather agency official from the ROKThe center previously issued a notice saying it suspected another test because the epicenter was located on the surface

    4 magnitude quake would be much smaller than the quakes caused by previous DPRK nuclear tests, the report saidAfter the incident, the center quickly organized seismological bureaus and geological institutions to evaluate the situation, it said

    Seismologists from the Chinese Academy of Sciences and the University of California Santa Cruz also published a joint report on Saturday that said tests had shown the quake "clearly falls in the natural phenomena category" and was similar to the last natural earthquake in the region, which was recorded in December 20043 magnitude quake, while the strongest, this month, resulted in a 6
