Answer: acid; acidic
Explanation:
You have a glass of pure water and add acidic lemon juice to it. This means that you are adding ACID to it, and the solution will become ACIDIC.
Pure water has a pH value of 7
Lemon juice has a pH value less than 7 i.e acidic
Therefore, addition of lemon juice to pure water will drop the latter pH from 7 to form a final solution that is ACIDIC.
The answer is c , it cant change a speed or a motion if it doesnt have a net force acting on it
Answer:
C6H12O2
Explanation:
The Jones reagent is a reagent in organic chemistry used to convert primary alcohols to carboxylic acids and secondary alcohols to ketones. Recall that tertiary alcohols can not be oxidized.
The compound 2-methyl-2,3-pentandiol contains one secondary and one tertiary alcohol. The secondary alcohol is oxidized to a ketone while the tertiary alcohol is not oxidized.
Hence the product of the oxidation using Jones reagent is 2-Hydroxy-2-methyl-3-pentanone with the molecular formula C6H12O2.
Answer : The concentration of
at equilibrium is, 0.244 M, 0.122 M and 1.267 M respectively.
Explanation :
The given chemical reaction is:

Initial conc. 0.439 0.317 0.877
At eqm. (0.439-x) (0.317-x) (0.877+2x)
As we are given:

The expression for equilibrium constant is:
![K=\frac{[HI]^2}{[H_2][I_2]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BH_2%5D%5BI_2%5D%7D)
Now put all the given values in this expression, we get:

x = 0.195 and x = 0.690
We are neglecting the value of x = 0.690 because equilibrium concentration can not be more than initial concentration.
Thus, the value of x = 0.195 M
The concentration of
at equilibrium = (0.439-x) = (0.439-0.195) = 0.244 M
The concentration of
at equilibrium = (0.317-x) = (0.317-0.195) = 0.122 M
The concentration of
at equilibrium = (0.877+2x) = (0.877+2\times 0.195) = 1.267 M
