In one compartment of a voltaic cell, a graphite electrode dips into an acidic solution of K2Cr2O7and Cr(NO3)3. In The other, a bar of solid tin dips into a Sn(NO3)2 solution. A KNO3 salt bridge joins the two compartments. The tin electrode is negative relative to the graphite. What is the oxidation half-reaction and what is the reduction half-reaction?

What are the first three quantum numbers for the electrons located in subshell 2s?

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?

Marcel just purchased 1.69 grams of iron fillings in order to make living putty for his 6 year old niece. how many moles of iron are made in his sample?
