Enter your answer in the provided box. The partial pressure of CO2 gas above the liquid in a bottle of champagne at 20°C is 4.5
sineoko [7]

<u>Answer:</u> The molar solubility of carbon dioxide gas is 0.17 M

<u>Explanation:</u>

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

C_{CO_2}=K_H\times p_{liquid}

where,

K_H = Henry's constant = 3.7\times 10^{-2}mol/L.atm

p_{CO_2} = partial pressure of carbonated drink = 4.5 atm

Putting values in above equation, we get:

C_{CO_2}=3.7\times 10^{-2}mol/L.atm\times 4.5atm\\\\C_{CO_2}=0.17mol/L=0.17M

Hence, the molar solubility of carbon dioxide gas is 0.17 M

A Grignard reagent and a ketone are reacted in ether solution and, followed by an acid workup, form a tertiary alcohol. Recall t
LUCKY_DIMON [66]

Answer:

                     Option-D (Acetone is a ketone. Grignard reagents will react with acetone to make an unwanted byproduct.) is the correct answer.

Explanation:

                    Grignard reagents are formed by reacting alkyl halides in the presence of ether and dry atmosphere at controlled conditions. The rinsing of glassware is not suitable to be done with Acetone. This is because of the reactivity of Grignard reagents towards the carbonyl compounds.

                    In the scheme below it is assumed that a grignard reagent (ethyl magnesium bromide) was reacted with pentan-2-one to synthesise a tertiary alcohol (3-methylhexan-3-ol). But when the glassware is rinsed with acetone, some acetone left in glassware (like Round bottom flask) will react with the grignard reagent and will produce corresponding tertiary alcohol (2-methylbutan-2-ol in this assumption).

Why do acids and bases neutralize eachother?
timofeeve [1]

Answer:

Explanation:

When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.
