c.) 0.050 M KOH and 0.015 M Ba(OH)2

d.) 0.088 M HClO4 and 0.022 M KOH

Part A

It takes 55.0 J to raise the temperature of an 10.2 g piece of unknown metal from 13.0∘C to 25.0 ∘C. What is the specific heat for the metal?

Part B

The molar heat capacity of silver is 25.35 J/mol⋅∘C. How much energy would it take to raise the temperature of 10.2 g of silver by 15.4 ∘C ?

I got 36.9 J for B and its correct

Part C

What is the specific heat of silver?

50mL of 0.1M weak acid is titrated with 0.1 strong acid. Pka is 5.20

What is the pH before the acid is added

pH after adding 10mL of acid

pH after 50 mL is added

pH after 60mL is added

Thank you for the help, I dont mind doing the amth, mainly need help with the equarions, thanks!

A 0.268 mol sample of PCl5(g) is injected into an empty 4.05 L reaction vessel held at 250 °C. Calculate the concentrations of PCl5(g) and PCl3(g) at equilibrium. 1.80 @ 250 C

Calculate the pH for 0.15M KCL, 0.15M Na2HPO4, and 0.15M NH4Cl. I need to use ICE tables to find the pH for these, but I am having trouble making them work.

Explain what “k” means, and how it can be calculated for the iodine clock reaction. As part of your explanation, include a sample calculation. Explain in one well-developed paragraph.

1) 362.11 g of O2 are contained in a 3.00 L high pressure tank at a temperature of 186°C. What is the pressure of the gas in torr?

2) A gas has a given volume. The moles of gas are doubled then the pressure is 1/3 of the original pressure. After the pressure change, the Kelvin temperature quadruples (increases 4 times of the original Kelvin temperature). By how much has the volume changed? Be specific (i.e. the volume is 1/3 of the original volume, the volume is 8 time greater, etc.). If you need more information to answer, explain what information is needed.

3) A helium balloon has a volume of 2.54 L at 1.04 atm and 24^oC. The balloon is then released. Calculate the volume of the balloon (in L) when the pressure is 312 torr and the temperature is–47^oC.

4) A vapor occupies a volume of 237.2 mL at a temperature of 90.6°C and a pressure of 734.6 torr. The mass of the condensed vapor is 0.978 g. Calculate the molar mass of the vapor (hint: Use the ideal gas law to find the number of moles).

5) A chemist mixed 10.00 g of a sodium carbonate solution with 10.00 grams of a hydrochloric acid solution in an open beaker. The reaction mixture fizzed. The final mass of the mixture was 19.31 g. Did this reaction violate the Law of Conservation of Mass? Why or why not? Be sure to explain your answer for full credit (hint – think common sense).

How many configurational isomers are possible for the following compounds?

B. 2,4-hexadiene

C. 3-chloro-1,4-pentadiene

How could you separate a mixture of starch, naproxen, and acetaminophen? Describe the laboratory procedure you would use.

8.00g of CH4 is allowed to burn in the presence of 6.00g of oxygen. How much (IN GRAMS) CH4, O2, CO2, and H2O remain after the reaction is complete?

Consider the combustion reaction between 26.0mL of liquid methanol (density = 0.850 g/mL) and 13.0L of oxygen gas measured at STP. The products of the reaction are CO2 (g) and H20 (g). Calculate the volume of liquid H2O formed if the reaction goes to completion and you condense the water vapor.
