When water condenses, aka changes from gas to liquid, it releases the most heat energy. Your answer is condensation.
Answer:
The answer to your question really depends on three things: how much water you have, how cold it is to start out, and how cold the things around it are. water actually freezes when it gets to 32 degrees fahrenheit (0 degrees celsius), but the time it takes to get there may be different. let's start with the first. if you take two glasses, and fill one with a tiny bit of water, and the other about halfway, then put them both in the freezer, the one with less water will freeze first (you can try this at home, but i recommend using plastic cups and not glass ones). now let's move on to the second part. let's say you have two glasses, and you fill one with really cold water that has been in the refrigerator, and the other with really hot water from the sink.

Answer:
CH₃CO₂H + H₂O ⇄ CH₃CO₂⁻ + H₃O⁺
Explanation:
A buffer is defined as the mixture of a weak acid and its conjugate base or vice versa.
For the acetic acid buffer, CH₃CO₂H is the weak acid and its conjugate base is the ion without H⁺, that is CH₃CO₂⁻. The equilibrium equation in water knowing this is:
<h3>CH₃CO₂H + H₂O ⇄ CH₃CO₂⁻ + H₃O⁺</h3>
<em>In the equilibrium, the acid is dissociated in the conjugate base and the hydronium ion.</em>
Answer:
Investigating how experimental conditions can effect the speed of a chemical reaction and give insight into reaction mechanisim and states.
Explanation:
Chemical kinetics is a process of investigation how experimental conditions can affect the speed of a chemical reaction and give insight into reaction mechanism and states.
- Chemical kinetics deals with two aspects chemical reaction; the speed at which reaction occurs(reaction rate) and the details of the steps involved in the reaction(reaction mechanism).
- The two aspects are closely related.
Answer:When two or more reactants are mixed and a change in temperature, color, etc. is noticed, a chemical reaction is probably occurring. However, these are not definite indicators.
Explanation: In a chemical reaction, there is a change in the composition of the substances. The following are indicators of chemical changes:
Change in Temperature
Change in Color
Noticeable Odor (after reaction has begun)
Formation of a Precipitate
Formation of Bubbles
