- A political candidate fighting for a smoke-free environment conducts an experiment in a room containing 1400 cubic feet of air that is initially free of carbon monoxide. Beginning at time t=0, cigarette smoke containing 4% carbon monoxide is introduced into the room at the rate of 0.1 cubic foot perminute, and the well-circulated mixture is allowed to leave the room at the same rate. If carbon monoxide levels in the air reach 0.012%, it is harmful to the human body. Find the time at which this unhealthy level is reached.9 Why did you do initial - final temperature instead of final temp - initial temp?As a concerned individual, this calls for an act to mitigate the problem on oceanacidification caused by anthropogenic emissions of CO2. In consideration to this perennialchallenge, we are left to answer a very important question: What can we do to help solve thisproblem? Your answer should consist at most five (5) sentences.
- Initial temp: 19.06 C 0.5 M concentration 200 mL of HCl and 200 mL of NaOH are combined in an insulated container. H+(aq) + OH-(aq) - - -> H2O (l) ∆H H++ = 0, ∆H OH−− = -230 kJ/mol, ∆H H2O = -286 kJ/mol ∆H reactants = ∆H H++ + ∆H OH−− = -230 + 0 = -230 kJ/mol ∆H reactants = -286 kJ/mol - ( -230 kJ/mol) = -56 kJ/mol H+ (aq) + OH− (aq) - - -> H2O (l) Using your observations and the stoichiometric relationships of the reaction, determine the number of moles that react. Show/upload your work.One of the many remarkable enzymes in the human bodyis carbonic anhydrase, which catalyzes the interconversionof carbon dioxide and water with bicarbonate ionand protons. If it were not for this enzyme, the body couldnot rid itself rapidly enough of the CO2 accumulated bycell metabolism. The enzyme catalyzes the dehydration(release to air) of up to 107 CO2 molecules per second.Which components of this description correspond to theterms enzyme, substrate, and turnover number?Prof. Neiman and Prof. James were first to discovered in 1973 that chlorofluorocarbons (CFCs) were depleting the Earth’sozone layer when released into the atmosphere. Once they reach the stratosphere, Clis released from the CFCs molecules by interaction with UV light. Free Cl atoms areable to react with ozone in a catalytic cycle that converts O3into the more stable O2.It is estimated that a single Cl atom is able to react with∼100000 O3molecules.Although CFCs production was banned in 1996, there are still a substantial numberof motor vehicle air conditioners (MVACs) that use CFC-12 (CF2Cl2) as refrigerant.The average CFC-12 emission rate from operating MVACs has been estimated tobe 59.5 mg per hour per vehicle (Zhang et al.Environ. Sci. Technol. Lett.2017).How much chlorine, in kg, is added to the atmosphere in a year due to 100 millionMVACs using CFC-12 as refrigerant?

- balance the following chemical equation, provide the mole to mole ratio and show the mechanism for the reaction. Solve it asap...Case 1: The class of Ms. FCG was performing a laboratory activity where they are to collect acetylene gas from dissolving calcium carbide in water. Before the activity started, she instructed her students to avoid using matches or lighter because the gas is flammable. When she went out of the laboratory to answer an urgent call, she heard a sudden explosion from the room. Base from the following actions, which should be the first thing Ms. FCG should do? a) Report the incident at the technician’s office b) Open all laboratory doors so the student can go out of the room c) Use the fire extinguisher to immediately put out the fire d) Turn on the fire alarm Justify your answer.In a study of the gas phase decomposition of sulfuryl chloride at 600 KSO2Cl2(g)SO2(g) + Cl2(g)the concentration of SO2Cl2 was followed as a function of time.It was found that a graph of ln[SO2Cl2] versus time in minutes gave a straight line with a slope of -4.28×10-3 min-1 and a y-intercept of -6.95 . Based on this plot, the reaction is________. (firest, zero, or second) order in SO2Cl2 and the rate constant for the reaction is min-1.
