How can you determine the specific heat of a metal using a calorimeter

Chemistry

Answer:

One can determine the specific heat of the metal through using the clarimeter, water, thermometer and using heat equations.

Explanation:

You can learn about heat effects and calorimetery through a simple experiment by boiling water and heating up the metal in it. Then, pour it into your calorimeter and the heat will flow from the metal to the water. The two equlibria will meet: the metal will loose heat into its surroundings (the water) and teh water will absorb the heat. The heat flow for the water is the same as it is for the metal, the only difference being is the negative sign indicating the loss of the heat of the metal.

In terms of theromdynamics, we can deteremine the heat flow for the metal becasue it would be equal to the mangnitued but opposite in direction. Thus, we can say that the specific heat of water qH2O = -qmetal.

In addition to reacting with gold (see Problem 21.21), aqua regia is used to bring other precious metals into solution. Balance
suter [353]

Aqua regia is used to bring precious metals into the solution .

3Pt(s)+ 4NO^{-} _{3} (aq)+18 Cl^{-} (aq) +16H^{+} =3Pt Cl^{2-} _{6} (aq) +4NO(g) +8 H_{2} O

This is the balanced reaction of Pt (platinum) .

<h3>What is aqua regia ?</h3>

It is a mixture of concentrated nitric acid and hydrochloric acid .there is three part of concentrated HCl and 1 part of concentrated nitric acid .

it is red or yellowish liquid . it is extremely corrosive and can cause skin burns . it is frequently used to dissolve gold and platinum .

The equation of reaction of aqua regia with gold :

Au + 4H^{+} +NO^{-} _{3} +4Cl^{-} =AuCl^{-} _{4} +NO +2H_{2} O

A chunk of pure silver weighs 20.0 g. What is its volume? Silver has a density of 10.49 g/cm cubed. Use unit analysis, NOT the D
julia-pushkina [17]

Answer: 1.91cm3

Explanation:

10.49g of silver dissolves is 1cm3 of solution.

Therefore 20g of silver will dissolve in = 20/10.49 = 1.91cm3 of the solution.
