This was a lab I performed where we mix aqueous 25ml HCl and 25ml NaOH and use a program called microlab to determine the cooling rate after the initial heating. We used a coffee cup calorimeter that had a stirring bar. At first, NaOH solution is by itself in the coffee cup calorimeter. It’s temperature was 23.02 C. I waited for 70 seconds and then added the 25ml of HCl to it. The temperature rose to 29.59 C, then began to cool down immediately. The cooling rate was y=0.0089x+26.1273 according to the program. The final weight of the solution was 47.147g. The moles of NaOH was 0.919M and HCl was 1.033M. The question: Using the volumes and concentrations of the HCl and NaOH solutions used in the experiment,calculate the moles of H2O formed in the neutralization reaction.

Using the ideal equation of state Jad A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 49.0 cm wide and 58.8 cm high. The maximum safe pressure inside the vessel has been measured to be 5.90 MPa. For a certain reaction the vessel may contain up to 15.1 kg of chlorine pentafluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction.
