- 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.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?fill in the missing reaction component: CuSO4(5H2O) + ______ --> CuSO4 + 5H2O

- Excess iron in the body, or hemochromatosis,can cause serious cell damage. One way to treat excess iron build up is to administer small molecules with a high affinity for iron. The small molecules form a complex ion with the iron, thus allowing the iron to be excreted. One small molecule that could be used to treat excess iron, L (M = 598.60 gmol-1), is shown on the right. The reaction between Fe3+ and L is: Fe3+(aq)+?(aq)⇌ Fe?3+(aq) Kf =4.68×1025 A 1.00L solution of 1.00 g/L of Fe3+(aq) has 1.00 mol of L added. What is the equilibrium concentration of iron(III), (i.e.,[Fe3+]eq) in the final solution?What is the mass-action expression, Qp, for the following reaction?Sn2+(aq) + ½O2(g) + 3H2O(l) ⇄ SnO2(s) + 2H3O+(aq)For the reaction: 3O2(g) ↔ 2O3(g) Kc = 4.0 x 10-13 at 2300oC. If a 0.500 M sample of oxygen gas is heated to 2300oC, what is the concentration of O3 in that cylinder?
- Write the expression for Kc for the following reactions. Ineach case indicate whether the reaction is homogeneousor heterogeneous.(a) 3 NO(g) ⇌ N2O(g) + NO2(g)(b) CH4(g) + 2 H2S(g) ⇌ CS2(g) + 4 H2(g)(c) Ni(CO)4(g) ⇌ Ni(s)+ 4 CO(g)(d) HF(aq) ⇌ H+(aq) + F-(aq)(e) 2 Ag(s) + Zn2+(aq) ⇌ 2 Ag+(aq) + Zn(s)(f) H2O(l) ⇌ H+(aq) + OH-(aq)(g) 2 H2O(l) ⇌ 2 H+(aq) + 2 OH-(aq)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?UCI Chemistry researchers, Prof. F. Sherwood Rowland and Dr. Mario Molina werefirst to discovered in 1973 that chlorofluorocarbons (CFCs) were depleting the Earth’sozone layer when released into the atmosphere.
