An 65.73 g sample of aluminum is placed on a 56.35 g sample of copper initially at 111.86^oC. If the heat is only transferred between the metals (with no loss to the surroundings) and the final temperature of both metals is 36.38^oC, what is the inital temperature (in ^oC) of aluminum?

Solutions

Expert Solution

Heat lose of Cu = Heat gain of Al

mcT = mcT

56.35*0.385*(111.86-36.38) = 65.73*0.902*(36.38-t)

t = 8.37⁰C

The initial temperature of Al = 8.37⁰C

1.) Two 100 g pieces of metal, one copper and one aluminum, that start at the same temperature are put in an oven for 2 minutes. When they are taken out of the oven, the copper feels warmer than the aluminum. This can be explained by the relative values of specific heat for the two metals. Copper must have a [ Select ] ["higher", "lower"] specific heat capacity than the aluminum, because [select one: higher heat capacity men a high...

An 8.68 gram sample of a mixture of aluminum carbonate and calcium carbonate is placed in a vessel equipped with a massless, frictionless piston. The initial volume can be assumed to be zero. The sample is heated to 800oC. This results in complete decomposition to the metal oxides and carbon dioxide. After the reaction, the metal oxides are titrated to equivalence with 246.2 ml of 0.84 M HCl. If the atmospheric pressure is 752 mm Hg, what is the maximum...

When a 1.50 g sample of aluminum metal is burned in an oxygen atmosphere, 2.83 g of aluminum oxide are produced. However, the combustion of 1.50 g ultrafine aluminum in air results in 2.70 g of a product, which is a mixture of 80% aluminum oxide and 20% aluminum nitride (% by mass). Use this information to determine the empirical formulas of aluminum oxide and luminum nitride.
