- Substances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?For the reaction shown, find the limiting reactant for each of the initial quantities of reactants. 2K(s)+F2(g)→2KF(s) Part A-1 molKmolK; 1 molF2molF2Express your answer as a chemical formula.

- In the course, you saw a very important principle, the Châtelier principle. According to this principle, we can optimize chemical reactions. Which means that we can vary the parameters of a chemical reaction to obtain more than one product or one other product. Indicate the change (s) in the reaction below that would increase its speed of reaction. Zn (s) + 2 HCl (aq) --> ZnCl 2 (aq) + H 2 (g)In order for Cl and NOCl to react and produce NO and Cl2 which of the following have to be true? a) NOCl must undergo a unimolecular rearrangement b) they must collide with sufficient energy to break or weaken some of the bonds present in the reactants c) they must collide with the proper orientation to facilitate the formation of new bonds present in the products d) b & c e) a, b & cReactions can have a wide range of yields. They can produce anything from fractions of percents all the way to almost exactly 100%. The reason that they almost never reach 100% is that almost all reactions are reversible, and once a certain concentration of product is reached, the reaction is no longer favorable. Hypothesize a way that you could force a reaction to reach 100%. Explain why it would work and why the reverse reaction wouldn’t occur.
