The brownish rock is a sedimentry rock was formed when things like sand, mud, or pebbles get laid down in layers. Eventually the layers are lithified.

The grey rock is a metamorphic rock and was when other rocks are changed because of heat or pressure. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure. They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks.

The red dots rock is an igneous rock. Igneous rock forms when hot, molten rock crystallizes and solidifies.

Draw the 2 resonance structures of Malachite Green, and indicate which one is the equivalent contributor, and which one is the m
Yuri [45]

The two structures at the right of the image are the greatest contributors to the resonance structure of malachite green.

<h3>What is resonance structure?</h3>

In some cases, one single structure is insufficient to explain the properties of a substance. Now, we know that in such cases we have to invoke more than one structure in order to efficiently discuss the chemistry of the compounds in question.

In this case, we can see from the image that the three structures of malachite green are all resonance structures. However, the two structures at the right hand side are the greatest contributors because they are more conjugated. Hence, the two structures at the right of the image are the greatest contributors to the resonance structure of malachite green.

Consider this hydrocarbon. A hexagon. Is this an aromatic hydrocarbon? Why or why not? Yes, because the carbon chain is made up
grin007 [14]

Answer:

C. No, because the carbon chain is composed of only a single ring.

Polycyclicity, having more than a single ring, is a property of only aromatic hydrocarbons. Therefore, if the hydrocarbon is not polycyclic, it is non-aromatic

Explanation:

Cyclic Hydrocarbons

These are organic compounds which are cyclic in structure. The compound cyclohexane involves a ring of six carbon atoms, each of which is also bonded to two hydrogen atoms

Aromatic hydrocarbons are cyclic ring organic compound which are based on the benzene ring structure.

A. If the hexagon contains single bonds, it is non-aromatic.

B. No. Having a ring shape does not on its own determine the aromaticity of a hydrocarbon.

C. Polycyclicity, having more than a single ring, is a property of only aromatic hydrocarbons. Therefore, if the hydrocarbon is not polycyclic, it is non-aromatic

D. Having double bonds within a ring is not a criteria for being aromatic. Both aromatic and non-aromatic hydrocarbons have double bonds within their rings. However, aromatic hydrocarbons have alternate double and single bonds within their 6-carbon ring structure.

Note: Since the structure of the required hydrocarbon is not shown, the explanation contains attachments of hexagonal structures of three hydrocarbons; one non-aromatic and the other two are aromatic. Cyclohexane is non-aromatic while Benzene and the polycyclic compounds are aromatic.

Crystals are made using supersaturated solutions of solids in water. These solutions hold more of the solute than they would at
Rudik [331]

Solubility controls the formation of crystals by the mechanism of oversaturation, therefore the correct answer is:

4. The water polo would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.

Crystals are solid structures where there is a fixed spatial arrangement of the molecules, there are many preparation methods, a very practical method and obtaining good crystals is from supersaturated solutions.

Solubility is the mechanism by which a supersaturated solution is formed, for this it is used that the water when heated has more energy and manages to dissolve a greater amount of solute, therefore by decreasing the temperature and consequently reducing the solubility the solution is over saturated.

When introducing some means of disturbance in the solution, the excess of solute is deposited in the form of crystals of excellent quality, this growth method is called hydrothermal synthesis

To achieve controlled supersaturation and crystals the temperature must be controlled precisely, to allow the formation of the crystals.

In conclusion, solubility controls the formation of crystals by the mechanism of over saturation, therefore the correct answer is:

4. The water polo would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.
