Medal, me understand. which best describes the oxidizing agent in this reaction? cl2(aq) + 2brmc003-1.jpg(aq) mc003-2.jpg 2clmc003-3.jpg(aq) + br2(aq) bromine (br) is the oxidizing agent because it gains an electron. bromine (br) is the oxidizing agent because it loses an electron. chlorine (cl) is the oxidizing agent because it gains an electron. chlorine (cl) is the oxidizing agent because it loses an electron.,

Which is mostly likely why many scientists reject the cold fusion theory

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
