Answer: $-5013.65\ J$

Explanation:

Given

No of moles $n=3$

Temperature $T=290\ K$

Initial volume $V_1=2\ m^3$

Final volume $V_2=1\ m^3$

Work done in constant temperature process is

$W=nRT\ln \left(\dfrac{V_2}{V_1}\right)$

Insert the values

$\Rightarrow W=3\times 8.314\times 290\ln \left (\dfrac{1}{2}\right)\\\\\Rightarrow W=-870\times 8.314\times \ln (2)\\\Rightarrow W=-5013.65\ J$

7. Copper can be coated on the surface of iron but not on silver? why

Lisa [10]

Answer:

Silver has greater electronegativity (pull on electrons) than copper, so it will be reduced rather than oxidized. Silver ions will plate out on copper metal. Sir the coating of iron with copper surface can be referred as IRON-COPPER PLATING.

Explanation:

Iron is used for the electroplating of so copper because iron falls above copper in the electrochemical series whereas silver will fall off below the copper in electrochemical series that makes it not reliable for the electroplating purpose
