When a strip of zn is placed in a beaker containing 0.1 m hcl, h2(g) evolves. if a strip of al is placed in a beaker containing 0.1 m hcl, does h2(g) evolve? a. yes; al is reduced and h+(aq) is oxidized. b. yes; al is oxidized and h+(aq) is reduced. c. no; al is reduced and cl-(aq) is oxidized d. no; al is oxidized and h2o(l) is produced. solution: the correct answer is b. this is a general chemistry question that falls under the content category âelectrochemistry and electrical circuits and their elements.â the answer to this question is b. since a new solid forms when al(s) is mixed with zn2+(aq), it is reasonable to assume that al(s) is more susceptible to oxidation than zn(s). it is a scientific reasoning and problem solving question because you are asked to bring together theory and observations to draw a conclusion.

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments,solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
