<u>Answer:</u> The equilibrium constant for the reaction is 54.47
<u>Explanation:</u>
The equilibrium constant is defined as the ratio of the concentration of products to the concentration of reactants raised to the power of the stoichiometric coefficient of each. It is represented by the term 
The given chemical equation follows:
The expression for equilibrium constant will be:
![K_{eq}=\frac{[HI]^2}{[H_2][I_2]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BH_2%5D%5BI_2%5D%7D)
We are given:
![[HI]_{eq}=1.3544\times 10^{-2}M](https://tex.z-dn.net/?f=%5BHI%5D_%7Beq%7D%3D1.3544%5Ctimes%2010%5E%7B-2%7DM)
![[H_2]_{eq}=4.5647\times 10^{-3}M](https://tex.z-dn.net/?f=%5BH_2%5D_%7Beq%7D%3D4.5647%5Ctimes%2010%5E%7B-3%7DM)
![[I_2]_{eq}=7.378\times 10^{-4}M](https://tex.z-dn.net/?f=%5BI_2%5D_%7Beq%7D%3D7.378%5Ctimes%2010%5E%7B-4%7DM)
Putting values in above expression, we get:
Hence, the equilibrium constant for the reaction is 54.47
Answer:
B. Geological Events and Lifeforms
Explanation:
The Earth's Geological time scale is mostly based on Geological Events and Lifeforms.
The Geological time scale provides a division of events on the earth into several time frames.
Each of the time units are based on events through the Earth's history and evolution of life.
The events are often recorded in rock strata and also as fossils which are the preserved remains of organisms.
Answer:
A) { + } Ge-Se { -}
B) { + } Ge-Br { - }
C) { - } Br-Se { + }
Explanation:
The (-)ive sign shall be placed for the atom with higher electronegativity, while the other atom will be electropositive.
a) Electronegativity of Ge = 2.01
Electronegativity of Se = 2.55
{ + } Ge-Se { -}
b) Electronegativity of Ge = 2.01
Electronegativity of Br = 2.95
{ + } Ge-Br { - }
c) Electronegativity of Br = 2.95
Electronegativity of Se = 2.55
{ - } Br-Se { + }
