A 54.2 g sample of an unknown metal is heated to 48.00 degrees Celsius and then placed in a coffee cup calorimeter. It is then placed in a coffee-cup calorimeter filled with water.

The calorimeter and the water have a combined mass of 183.1 g and an overall specific heat of 1.34 cal/g•°C.

The initial temperature of 10.2°C when the metal is added.

What is the specific heat of the unknown metal?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
