VS. Use a second thermometer/temperature probe to check the temperature. 6. Use a 100 ml. graduated cylinder to measure 50.0 mL of hot water y Record the temperature of the "hot" water in your lab notebook. 0 Mix the hot water with the cold water in the calorimeter replacing the lid quickly, and the record the temperature of the combined solution every 15 seconds for six minutes (24 readings). Note:...

Show your work for all calculations, you MUST justify your answer to get credir. Answers should reflect the appropriate number of significant figures and include labels. 1 Answer the following questions about the enthalpy of reaction for the neutralization of HCL using NaOH: a. Report your experimentally measured molar enthalpy for this neutralization reaction below b. Write the ionic and also the net ionic equations for the reaction (include state symbols). Part I. Determination of the Heat Capacity of a...

2. Answer the following questions about the neutralization reaction of nitric acid using sodium hydroxide (see Equation 1 from the Introduction): a. Write the ionic and net ionic equations for the reaction. b. How does the molar enthalpy of reaction for the neutralization of nitric acid compare to the value you obtained for the neutralization of hydrochloric acid? What would you expect it to be when you compare the net ionic equations for the two reactions? Explain. livier, using Eos...

my chemistry lab did the composition of hydrogen peroxide. i
am having trouble trying to fugure out how to fill in the table. i
dont understand why “s” is added to pvnrt and how to apply that to
my equation. these are the steps on how to solve but i believe they
are rather confusing. please help! thank you!
