Anion analysis
POSTLABORATORY ASSIGNMENT 1. An iodide/chloride/sulfate unknown solution gave a yellow precipitate with AgNO The supernate did not react with Ba(NO)). The yellow precipitate did not dissolve in NH, H,O. After centrifuging the supernate was acidified with HNO, and gave a white precipitate. State the ion(s) present in the unknown solution. An iodide/chloride/sulfate unknown solution plus AgNO, gave no reaction. The solution was treated with Ba(NOs)2 and produced a white precipitate. State the ion(s) present in the unknown solution....

I'm having trouble writing this code, can some help me? Step 1: Capturing the input The first step is to write a functionGetInput()that inputs the expression from the keyboard and returns the tokens---the operands and operators---in a queue. You must write this function. To make the input easier to process, the operands and operators will be separated by one or more spaces, and the expression will be followed by #. For example, here’s a valid input to your program: 6...

(b) The Art department decided to order some painting sets. Each set contains one packet of paper and 3 coloring ink pens. Packets of paper normally have 20 sheets each, but 5% of packets are overfull and have more than 20 sheets of paper. In addition, each ink pen has a 2% chance of leaking during shipping Assume that the painting sets are packed one at a time into a shipping box, up to and including the first set with...
