- doug began preparing laboratory surface disinfectant from chlorine bleach. he put on a chemical resistant apron and gloves and then removed the bleach container from the special chemical cabinet. he carefully placed the container on the laboratory benchtop and began to add the chlorine bleach to distilled water. nearby workers began complaining of burning eyes. doug was reprimanded by the supervisor. Explain why.Read and interpret the following information using the following abstract from a scientific journal article. In 2-3 sentences, summarize what you understand from this researchPossible death for animals and human being is expected for 430 ppm of chlorine gas exposure in 30 minutes. Cl2 released from MGPI approximately 45 minutes. Determine the probable death percentage from this toxic release accident.
- Scrubbers are a type of pollution control technology installed on industry smokestacks to capture sulfur dioxide before it is emitted to the atmosphere. Once collected, the sulfur dioxide can be used to manufacture sulfuric acid, which can be sold to other companies that make detergents. Explain how the use of scrubber technology benefits both industry and the environment.Describe the process of catalytic cracking used in the petroleum refining industry Your answer must also include: · A balanced chemical equation, physical states included, and reaction conditions stated · Examples of a product formed from catalytic cracking (in petroleum refining) and its useCan you help me answer this type of question from my study review package please
- In any manufacturing process, reaction monitoring ensures that a chemical reaction proceeds as expected. Table 1 shows the monitoring data for the formation of chlorohexane, collected using a technique called gas chromatography. Note that the concentrations of the chlorohexane solutions are given in millimoles per litre (mmol l–1). The abbreviation mM (millimolar) is frequently used. Plot a graph of the data in Table 1. The graph should be drawn on graph paper or use fine grid if it’s drawn on Excel. Elapsed Time/Hours Concentration of Chlorohexane/mM 0 0 2 40 4 65 6 80 8 90 10 95 12 99The research group has recently focused on identifying the chemical properties of fluorocarbons, such as CF4 and C2F4. These fluorocarbons display a very different reactivity compared to hydrocarbons. Teflon (C2F4)n is a fluoropolymer. When Teflon is mixed with silica at high temperature, all solid decomposes into gases. Write down the reactions that can take place during the process and explain your reasoning.state five causes of accidents in a chemical laboratory and explain how they can be avoided
- The chart shows average CO2 emissions for fossil fuel vehicles (gasoline, diesel, and hybrid gas‑electric), as well as electric vehicles. The ordinate is mg CO2 per mile driven per pound mass of the vehicle (called curb weight). For electric vehicles, CO2 emission varies in U.S. states because of the mix of fuels used to generate electricity. If electricity came entirely from solar power, there would be little CO2 associated with its production. California has the lowest CO2 emission for producing electricity and Ohio has the highest because it depends heavily on coal‑fired power plants. The chart does not include CO2 emission from manufacturing vehicles. When normalized for distance driven by each kind of vehicle before it is scrapped, CO2 emission associated with manufacturing electric vehicles is estimated to be 25–75% greater than CO2 emission associated with manufacturing gasoline and diesel vehicles. If manufacturing were included, CO2 emission associated with electric vehicles…MN IN The 1995 Nobel Prize in Chemistry was shared by Paul Crutzen, F. Sherwood Rowland, and Mario Molina for their work concerning the formation and decomposition of ozone in the stratosphere. Rowland and Molina hypothesized that chlorofluorocarbons (CFCS) in the stratosphere break down upon exposure to UV radiation, producing chlorine atoms. Chlorine was previously identified as a catalyst in the breakdown of ozone into oxygen gas. Using the enthalpy of reaction for two reactions with ozone, determine the enthalpy of reaction for the reaction of chlorine with ozone.
