Answer:
The answer to your question is Argon
Explanation:
Electron configuration given 1s² 2s² 2p⁶ 3s² 3p⁶
To find the element whose electron configuration is given, we can do it by two methods.
Number 1. Sum all the exponents the result will give you the atomic number of the element.
2 + 2 + 6 + 2 + 6 = 18
The element with an atomic number of 18 is Argon.
Number 2. Look at the last terms of the electronic configuration
3s² 3p⁶
Number three indicates that this element is in the third period in the periodic table.
Sum the exponents 2 + 6 = 8
Number 8 indicates that this element is the number 8 of that period without considering the transition elements.
The element with these characteristics is Argon.
One system must have higher kinetic energy than the other system
Answer: Silver has an atomic mass of aproximately 107.9.
Explanation:
1 mole of silver atoms = 107.9g and there are 6.02x10^23 atoms in one mole.
Answer:
![Kc=[Cl2]2/[HCl]4[O2]](https://tex.z-dn.net/?f=Kc%3D%5BCl2%5D2%2F%5BHCl%5D4%5BO2%5D)
Explanation:
Hello,
In this case, the law of mass action, allows us to study the mathematical expression regarding an equilibrium chemical reaction allowing us to see a relationship between the equilibrium constant and the concentration of both the products and reactants at equilibrium for either gaseous or aqueous substances only. Such relationship is assembled as the quotient between the concentration of products at equilibrium over the concentration of reactants at equilibrium equaling the equilibrium constant. Thus, for the given chemical reaction, such expression will have the concentration of chlorine at the numerator and both the concentrations of hydrogen chloride and oxygen at the denominator since water is liquid so it is not included in the shown below equation:
![Kc=\frac{[Cl]^2}{[HCl]^4[O_2]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BCl%5D%5E2%7D%7B%5BHCl%5D%5E4%5BO_2%5D%7D)
Therefore the answer is: Kc=[Cl2]2/[HCl]4[O2].
Best regards.
Answer:
Love for Music
Explanation:
This is one example of many non-physical traits. In the womb a mother can listen to her favorite music and the growing baby could grow to like it in the womb!
This is just one of the many other traits that could be passed to their offspring.
Hope this Helps!
