You computed the specific heat for each of the four metals using the formula below: Check all items that you used, either directly or indirectly, each time you did this computation.
the first law of thermodynamics (heat lost by a metal equals the heat gained by the water)
a) the ability of heat to flow from a hot object to a cooler one
b) masses for the metal and the water in the calorimeter
c) temperature changes for the water and the metal
d) the known specific heat of the water

Which statement describes james chadwick’s discovery.

A1.5l container holds p.50 grams of an unknown gas at a pressure of 0.44 atm and a temperature of 50.c what is the molar mass of the unknown gas

Answer asap need to be answered 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.
