Answer:
Now this just because of decrease in acceleration while moving in upward direction. Just because she faced the upward hill and to accelerate at the same rate while moving upward always need some upward force but as janice was not applying any sort of large amount of force but however she was skating she faced faced the decrease in acceleration.
Explanation:
Due to decrease in acceleration she slowed downed while moving upward.
The graph attached can be well understood to analyze the scenario.
Answer:
See explanation below
Explanation:
This reaction is known as Ketone hydrolisis in acid medium. This involves the formation of an hemi cetal, and then, the acetal. This is often used to convert ketones or aldehydes in ethers.
The first step involves the reaction with the acid. The carbonile reacts with the acid and forms an alcohol there. The next step is the reaction of the alcohol, in this case, the methanol to form the hemi cetal. Then in the third step, we repeat the first step, using acid to turn the OH group into a great leaving group such water. Then the water leaves the molecule, leaving the space wide open in the next step for methanol, and the acetal is formed.

These are the characteristics that apply:
- In a solution taste sour: which is consequence of the H+ concentration.
- Corrode metals: the H+ ion reacts with the metal producing a salt and water
- Produce hydronium ion in solution: as per the Bronsted - Lowry definition an acid is a substance that donates a proton, H+.This proton will react with H2O to form H3O+ (hydronium), as per this scheme:
HA + H2O --> A(-) + H3O(+)
