Answer:
The hot water remains at the top of chilled water.
Explanation:
The hot water remains at the top of chilled water because hot water has less denser as compared to chilled water. Due to higher density of chilled water, it remains at the bottom due to its greater mass while on the other hand, the hot freshwater goes upward and spreads at the top of the chilled water due to lower mass so when the hot water is added to the chilled water, hot water remains at the top.
<span>Double-replacement and acid-base reactions are examples of redox reactions.

Answer:
See below explanation
Explanation:
Checking the reduction potencials:
Zn⁺²/Zn° , E° = -0.76 V
Fe⁺²/Fe° , E° = -0.44 V
For which Fe⁺² will be the ion that will reduce, and Zn° will lose electrons
ANODE: Zn° ⇄ Zn⁺² + 2e⁻
CATODE: Fe⁺² + 2e⁻ ⇄ Fe°
NET CELL REACTION: FeSO₄ (ac) + Zn° ⇄ Fe° + ZnSO₄ (ac)
In the external circuit, electrons will migrate from anode (Zn|Zn⁺²) to catode (Fe|Fe⁺²), and in the salt bridge; anions migrate from Fe⁺²|Fe compartment to Zn|Zn⁺² compartment
The statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.
<h3>What is a pond?</h3>
Pond is an inland body of standing water, either natural or man-made, that is smaller than a lake.
A bog is an area of decayed vegetation (particularly sphagnum moss) which forms a wet spongy ground too soft for walking.
This means that a pond can become a bog when existing plants in the pond decays until the land becomes soft.
Therefore, the statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.
