Galactic recycling is a natural phenomenon in which the stars expel some gas into the space so that it would mix with the interstellar medium. As a result, this would produce new younger stars. So, basically, the concept done here is the mass and energy conservation. In order to create new species, the energy must come from another source.
Answer:
- <u>First choice: 0.042</u>
Explanation:
Given decomposition reaction:
- 1PCl₅ (g) ⇄ 1PCl₃ + 1Cl₂(g)
Equilibrium constant:
Stoichiometric coefficients and powers equal to 1 are not usually shown as they are understood, but I included them in order to shwow you how they intervene in the equilibrium expressions: each concentration is raised to a power equal to the respective stoichiometric coefficient in the equilibrium equation.
So, your calculations are:
![K_{eq}=\frac{(0.020M)(0.020M)}{0.0095M}=0.042M](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%280.020M%29%280.020M%29%7D%7B0.0095M%7D%3D0.042M)
C. Sn (tin) is a metal, Si (silicon) is a metalloid, and C (carbon) is a nonmetal
