Answer : The value of 
for the final reaction is, 184.09
Explanation :
The equilibrium reactions in aqueous solution are :
(1) 
(2) 
The final equilibrium reaction is :
Now we have to calculate the value of for the final reaction.
Now equation 1 is multiply by 2 and reverse the equation 2, we get the value of final equilibrium reaction and the expression of final equilibrium constant is:
Now put all the given values in this expression, we get :
Therefore, the value of for the final reaction is, 184.09
The correct answer is D. Light bulbs
Explanation:
In chemistry, halogens are a group of elements characterized for being non-metallic elements (they cannot conduct heat or electricity), and for forming salts. In terms of uses, halogens had been used mainly as part of disinfectants, as well as, in the production of light bulbs and lamps. This last application implies small quantities of halogens such as iodine are used in the mechanism of bulbs or lamps and this is a better option than other elements as it increases the life of the bulb and makes bulbs to a whither color. According to this, one use of halogens is light bulbs.
In order to see which species has the strongest dispersion forces, you need to calculate their molar mass, because the higher the molar mass, the stronger the dispersion forces.
Since E. C8H18 has the highest molar mass, its dispersion forces are also the strongest ones.
Answer:
D
Explanation:
solution made by mixing 100 mL of 0.100 M HClO and 50 mL of 0.100 M NaOH Can resist pH change when there is little addition of either acid or base, hence it is a buffer solution
