To study the photochemical decomposition of aqueous bromine exposed to bright sunlight, we dissolved a small amount of liquid bromine in water contained in a glass jar and placed under direct sunlight. The following data were obtained at 25\deg C:\table [[Tiempo (min ), 10, 20, 30, 40, 50, 60], [Ppm, 2.45, 1.74, 1.23, 0.88, 0.62, 0.44]] Determine the reaction rate order and the specific reaction rate constant: a) Differential method ( The method for obtaining the derivatives is left to your decision) Tiempo (min) Ppm Br₂ 10 2.45 20 1.74 Ć 30 1.23 40 0.88 50 0.62 60 0.44

Given       Zn(s)| Zn 2+ (aq) (1M)  ||  Ag+2+ (aq) (1M) | Ag (s)                Eocell = 1.562V  What will the Ecell be if the [Zn2+] = 0.75M and [Ag+] =0.25 M  at 40.00oC (313.15K)?  The overall reaction is                                                   Zn(s)  +  2 Ag+ (aq)   -->  2 Ag (s)  +  Zn 2+ (aq) (Answer has 3 digits after the decimal)

A 53°F Cloudy The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H₂O). Note: "major" chemical species are those present in concentrations greater than 10 mol/L. major species present when dissolved in water 0 0 compound glycerol copper(11) lodide Explanation 7 A methanol 2 2 W formula alt CHO CH, OH Cul, Check 3 H…

12:27 12-2 Analyzing Data... NAME Energy (kJ) NAME 1000 Many chemical reactions involve a change in energy. When the energy of the reactants is greater than the energy of the products, the reaction gives off heat and is exothermic. When the energy of the products is greater than that of the reactants, the reaction must absorb energy from the surroundings to occur and is endothermic. If the intermediate stage (the activated complex) is of a higher energy, then the reaction can only take place if the reactants are given an initial energy input (the activation energy). The graph shows energy diagrams that indicate how the energy changes as three reactions occur.
