Question 2. Answer all parts of this question a) A shell and tube heat exchanger is to heat 10,000 kg h–1 of water from 16 to 84°C using hot oil entering at 160°C and leaving at 92°C. The oil will flow through the shell of the heat exchanger. The water will flow through 11 brass tubes of 22.9 mm inside diameter and 25.4 mm outside diameter, with thermal conductivity 137 W m–1 K–1, with each tube making two passes through...

Barry is currently obese and would like to lose weight. Barry is watching television and sees two different infomercials about weight loss products. The first infomercial is for a weight loss "supplement, called ICBINM (I Can't Believe It's Not Meth), the customer takes daily to "increase metabolism and energy". The infomercial for ICBINM shows 3 different verified customers who used the product and lost a lot of weight. The second infomercial is for a weight loss "program", called TNKD (The...

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...
