Answer:
copper
Explanation:
metallic bonds occur among the metal atoms where iconic bonds join metal and nonmetals metallic bonding joins a bolt of metal atoms a sheet of aluminum foil and a copper wire are both place where you can see metallic bonding in action the Sea of electrons that is free to flow about the crystal of positive metal ions
Answer:
Option (D)
Explanation:
A stream is a narrow river that originates from a source area. These source areas are usually the high altitude mountains in which the high amount of snow is gathered in the winter season and subsequently melts during the summer season. As a result of which the streams and rivers flows and mix up with the seas and oceans. These source areas are commonly termed as the headwaters or the stream head.
The direction towards the headwaters of a stream or moving against the flow direction is generally known as the upstream direction.
Hence, the correct answer is option (D).

Answer:
a). P = 688 atm
b). P = 1083.04 atm
c).Δ G = 16.188 J/mol
Explanation:
a). Fugacity 'f' can be calculated from the following equations :
where, P = pressure , Z = compressibility
Now, the virial equation is :
........(1)
Also, PV=ZRT for real gases .......(2)
∴ 
So from the fugacity equation ,
Putting the value of P = 500 atm in the above equation, we get,
f = 688 atm
b). Given f = 2P
∴ P = 1083.04 atm
c). dG = Vdp -S dt at constant temperature, dT = 0
Therefore, dG = V dp
