Consider the proposed design for a steam power plant. The water is boiled and vapor is used to spin the turbine. From the turbine, the vapor is sent directly to the pump driven by the same turbine, and back to the boiler. It is claimed that considering some heat losses and friction losses, the efficiency of this device may approach 80%. Required:
a. Is any law of thermodynamics is violated? If so, which one, and why?
b. How would you this system to avoid the violation?

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm

: )

the answer is minerals.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
