You carefully place lettered candy with the letters facing up in water. Without disturbing the water, you notice the letters flo

at above the candy as the solution process takes place. Discuss why this would happen in terms of soluble, insoluble, miscible, immiscible, and water as the universal solvent. Describe the general conditions under which solids are most soluble in liquids.

Oil-based food coloring used to make the letters, won't dissolve in water. According to some sources, oil-based food coloring is either insoluble or immiscible in water. Because it is present in more solutions, water serves as the universal solvent.

<h3>Universal solvent:-</h3>

A substance that displaces most compounds is known as a universal solvent. Because it dissolves more chemicals than any other solvent, water is known as the universal solvent.

<h3>What chemicals lack solvability?</h3>

Sand, plastic, wood, metal, glass, and cloth are examples of insoluble materials. At standard conditions of pressure and temperature, these compounds never dissolve in water or any other solvent. Other examples of insoluble materials are sugars and inorganic salts.

In what way do the oceans and the forests perform a similar function in the carbon cycle, under normal conditions?.
ikadub [295]

Both take carbon dioxide out of the atmosphere.

The ocean absorbs much of the carbon dioxide released when fossil fuels are burned. This extra carbon dioxide lowers the ocean's pH through a process called ocean acidification. Both are important elements for all life on earth. Relationship between the water cycle and the carbon cycle. The sun's energy drives both the carbon cycle and the water cycle.

Recall that sunlight water and carbon dioxide combine in green plants via photosynthesis to produce carbohydrates. The ocean also regulates the Earth's climate. They determine the weather by telling temperatures and determining rainfall, droughts, and floods. It is also the world's largest carbon sink, with an estimated 83% of the global carbon cycle circulating in seawater.

I NEED AN ANSWER TO THESE QUESTIONS ASAP!! I GOT A TEST TOMORROW ON THIS!!!

18.The octet rule tells us that in every chemical reactions, elements will either gain or lose electrons to attain the noble gas electron configuration. This stable<span> electron configuration is known as the octet configuration since it is composed of 8 valence. Oxygen’s electron configuration is 1s2 2s2 2p4. So when</span> oxygen reacts with other elements to form compounds, it completes the octet configuration by taking 2 electrons from the element it reacts with

 

19. Actually pure metals are made up not of metal atoms but rather of closely packed cations (positively charge particles). These cations are then surrounded by a pack of mobile valence electrons which drift from one part of the metal<span> to another. This is called metallic bond.</span>

 

20. This is the energy which is needed to break a single bond. When the dissociation energy is large, this means that the compound is more stable. Since carbon to carbon bonds have high dissociation energy, therefore they are not very reactive.

 

21. Network solids are type of solids in which the atoms are covalently bonded to one another, so they are very stable. It takes higher temperature to melt them because breaking these covalent bonds required greater energy. Some examples are:
- Diamond
<span>-Silicon Carbide</span>

What happens when you touch two hot bowls made of different materials? The wooden and metal bowl are both at the same temperatur
Julli [10]

Answer:

Explanation:

Both metal and wooden bowls are at the same temperature . But wood is non-conductor of heat whereas metal is conductor of heat .

If we touch the wooden bowl , heat flows from hot to cold object . Since the finger is at higher temperature , heat flows from finger to wooden bowl . But , since wood is non conducting , it does not allow heat to be conducted through it . Hence very less heat will be conducted from our finger .

On the other hand , if we touch a metal bowl , heat flows from finger to the metal bowl , without any hinderance . Hence rate  of heat flow will be fast in case of metal bowl . As a result of it , we feel cool in touching metal bowl . This feeling will be absent in case of wooden bowl.
