Answer:
C. gold atoms
Explanation:
Metallic bonds are found between atoms of metals. Since gold is the only metal given here, it is the solution to the problem.
Metallic bonds join atoms of metals and alloys together.
The formation of this type of bond is favored by large atomic radius, low ionization energy and a large number of electrons in the valence shell.
The metallic bond is actually an attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by all atoms losing their outermost shell electrons.
Yes P3l10 is a proper compound
Answer:
The answer is 12.35
Explanation:
From the question we are given that the concentration of 
is 
Generally The rate equation is given as
![K_{w} = [H^{+} ][OH^{-} ]](https://tex.z-dn.net/?f=K_%7Bw%7D%20%3D%20%5BH%5E%7B%2B%7D%20%5D%5BOH%5E%7B-%7D%20%5D)
and 
the rate constant has a value 
Substituting and making [
] the subject we have
![[OH^{-} ] = \frac{1 * 10^{-14}}{[H^{+}]} = \frac{1 * 10^{-14}}{8.1 *10^{-6}} =1.235 * 10^{-9}](https://tex.z-dn.net/?f=%5BOH%5E%7B-%7D%20%5D%20%3D%20%5Cfrac%7B1%20%2A%2010%5E%7B-14%7D%7D%7B%5BH%5E%7B%2B%7D%5D%7D%20%3D%20%5Cfrac%7B1%20%2A%2010%5E%7B-14%7D%7D%7B8.1%20%2A10%5E%7B-6%7D%7D%20%3D1.235%20%2A%2010%5E%7B-9%7D)
![[OH ^ {-}] = 1.235 * 10^{-9}M](https://tex.z-dn.net/?f=%5BOH%20%5E%20%7B-%7D%5D%20%3D%201.235%20%2A%2010%5E%7B-9%7DM)
Multiply the value by 
as instructed from the question we have
Answer = 
Hence the answer in 2 decimal places is 12.35
I believe that it is 187.56 g/mol
Answer:
Explanation:
During that process of being exposed to air and water while being left outside or in the elements for an extended period of time, a variety of different types of rusts can form, but the most common form is Fe2O3. Rust only forms on the outside of a metal surface because it requires exposure of oxygen and water to rust.
