Answer: 4.32g
Explanation:
MM of H2 = 1 x 2 = 2g/mol
2g of H2 contains 6.02x10^23 atoms.
Therefore Xg of H2 will contain 1.3 x 1024 atoms i.e
Xg of H2 = (2 x 1.3 x 1024) / 6.02x10^23 = 4.32g
Answer:
true because the bonds cannot be broken down
The first two ionization energy of nickel are expressed as:
Ni(g) = Ni^+(g) + e^- Ni^+(g) = Ni^2+(g) + e^-
IOnization energy os the energy that is neccessary in order to remove one mole of electrons from an atom.
Hope this helps.
Answer:
in the water, plants and small organisms like plankton take up mercury through passive surface absorption or through food intake. ... Methylmercury biomagnifies through the food chain as predators eat other organisms and absorb the contaminants that their food sources contained.
