Your lab manual lists the cost per ton, environmental impact, and lowest effective temperature of the solutes used in Experiment FPD. It also lists these same characteristics for a commercial ice melt blend. There are other pure compounds that are marketed as ice melts. Select one and determine if this pure compound would be cheaper, less environmentally impactful, and/or more effective at lower temperatures than the options listed in your manual. To do so, you will have to do some research. Include a formal citation for your source(s) at the conclusion of your answer.

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.

What is the mass of oxygen gas is consumed in a reaction that produces 4.60mol so2

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
