Answer:
D
Explanation:
The formula for calculating kinetic energy is 1/2mv^2, where m is the mass and v is the velocity or speed of the object. Since all of the balls have the same mass, the one with the highest speed or velocity will have the highest kinetic energy. Hope this helps!
Answer:
No additional information is required in order to calculate the molality of the solution.
Explanation:
Mole fraction of water = 
Mole fraction of sucrose = 

From the given mole fraction of water mole fraction of sucrose can be determined.
And from both values of mole fraction moles of water and sucrose can also be calculated.


After calculating the moles of water convert them into mass of water in grams and then change that into kilograms say that be M'.
Finally we can determine the molality of solution ;

Molality of the sucrose solution ;

From this we can conclude that no additional information is required in order to calculate the molality of the solution.
Answer:
esters
Explanation:
The -OR group of the alcohol replaces the -OH of the carboxylic acid, forming an ester. See attachment for condensed mechanism.
