(Click Slide). Molecular compounds are everywhere in our every day lives! Sugar cane, for example, is a molecular renewable compound. Although we do not think about it, all of our consumer products that we buy and use are made of molecular compounds that come from various natural resources. Natural resources can be categorized into 2 divisions: renewable resources and non-renewable resources.
(Click Slide). Renewable resources are those that be replenished naturally and over a short period of time. Examples of these include wood and water. Non-renewable resources are those that are available in limited supply. Common non-renewable resources are crude oil and coal. If resources are over-consumed and not managed sustainably, they will be depleted.

(Click Slide) Due to adhesion, capillary action occurs in plants. Water absorbed from the roots sticks to the walls of xylem vessels in plants, and cause an upward motion. Sometimes, you may see that when you wet a paper towel, the water quick travels up the towel. Capillary action occurs when adhesive forces are stronger than cohesive forces.
(Click Slide) Another unique property of water is its high specific heat capacity. Due to the strong hydrogen bonds that exist between water molecules, a lot of energy is needed to break down the bonds. As the Particle Theory states, particles move faster and further apart when heated. This is why water helps maintains a moderate temperature on Earth and different bodies of water, crucial for the survival of organisms.
(Click Slide) Hydrogen bonding is also applied in human DNA. Hydrogen bonding occurs between base pairs in a strand of DNA. It allows DNA to have its double helix shape, and allows for the replication of DNA strands. I am not going to go too deep into this, but base pairs are the two nucleobases you see in this image on every strand in the double
Nonrenewable resources are more scarce because there is only limited supplies. An example of nonrenewable resource
3. It takes a lot of energy to raise the temperature of water because of its high heat capacity. The strong hydrogen bonding between water molecules makes it harder to change the temperature of the water because it takes a lot energy to weaken the hydrogen bonds. When water evaporates, it takes a lot of heat with
The specific heat capacity for liquid water is 4.18 J/g(C), and compared to other metals like Zinc and Tin, the specific heat capacity is much greater. Please explain in 100 words or less why liquid water’s structure leads to a high specific heat capacity, and how does water’s higher specific heat capacity aid our lives?
Sugar cane is composed of six species of perennial grasses of the genus Saccharum L., in tribe Andropogoneae of the Gramineae. There are two wild species, S. spontaneum L. and S. robustum Brandes & Jeswiet ex Grassl, and 4 cultivated species, S. officinarum L., S. barberi Jeswiet, S. sinense Roxb., and S. edule Hassk. (Purseglove 1979). The four cultivated species are complicated hybrids, and all intercross readily. All commercial canes grown today are inter-specific hybrids (Wrigley 1982).
On the LSU Ag Center website there is a PDF file that provides information on the burning of Sugarcane. Out of all the domestic sugar industries, Louisiana has the most historic and oldest of them all. Sugarcane arrived in Louisiana with the Jesuit priests in 1751 and, in 1795, Etienne DeBore “granulated sugar on a commercial scale at Audubon Park in New Orleans” (Legendre 1). The Louisiana sugarcane industry is in its third century of existence, celebrating its 200th year of sugar production in 1995.
This research paper will interpret the United States sugar industry protections within Macroeconomics insights. The sugar industry in United States consists principally of sugarcane and sugar beets production. The country is ranking in the fifth place in the world consumer and the major production of the product (US Sugar, 2017). The greater concentration of crop sugarcane it is in the State of Florida, followed by the states of Louisiana, Texas and Hawaii, and the sugar beets crop are in the states of North Dakota and Minnesota (The Economic, 2011). In addition, there are rules and statutes in order to the United States meets the standards to produce, imports, sale and consumptions of the traditional sweetener, which are the policy quotes,
viii) Because of transpiration pull and cohesion or adhesion of water molecules, the water moves in the xylem vessels as
Water has a high specific heat capacity compared with other liquids. This means that a large increase in energy results in a comparatively small rise in the temperature of the water. This is because much of the heat absorbed is used to break the hydrogen bonds that hold the molecules together. Water is good at maintaining its temperature at a steady level, irrespective of fluctuations in the temperature of the surrounding environment. This is important because the range of temperatures in which
In the capillary action experiment, water molecules adhered to the positively charged glass tubing while the adhesive forces of hydrogen bonding kept the water from falling back down to the beaker. It was best seen in the smallest diameter tube where water molecules have more space to spread out and the negatively charged O- ion adhered to the glass tubing until the forces of gravity equaled it out, thus forcing the water from climbing any higher. This explains how water can climb up and down the internal structure of a tree to exist through its leaves, which is critical in plants being able to survive on Earth. However, our capillary action experiment is not exactly what happens in nature. We observed carnation flowers and celery placed in food dye and water during our lab. The dye reached much higher in the flowers and celery than it did in our tube. This shows that water can reach much higher than what we observed in our glass
Renewable resources can be used and replaced. Examples are fish stocks, forests, or water. They are resources that will refilled by itself through reproduction, plantation through the nature cycle. They are natural resources that technically regenerate itselves through ecological process.
Another example of a nonrenewable energy includes nuclear energy. Although, the production of nuclear energy is the renewable energy source, the materials used to create it is not. Nuclear energy is created by splitting or fusing uranium atoms (nuclear fission/fusion) and produces electrical energy. It also produces radioactive waste, which is very
“S-cane” is Sugarcane Juice product packaged in tetra pack. Sugarcane juice is one of the most popular and widely used juice in Gujarat and India. It is healthy, good in taste and low in cost. But it cannot be preserved for long time. In Gujarat
Nonrenewable is a type of energy that cannot renew itself. According to the U.S Energy Information Administration, different natural resources such as coal, oil, natural gas, and many others take thousands of years to form naturally. Nonrenewable resources are known to not be able to replace themselves as fast as the resources are consumed.
Renewable energy is energy or power that is created from natural resources such as wind power, oceanic waves, and the sun. These resources can be used to replace other energy generators such as electricity and gasoline.
Renewable energy is defined as energy that is collected from resources which are naturally replenished by nature, such as sunlight, wind, rain, tides, waves, and geothermal heat. Quick deployment of renewable energy is resulting in noticeable changes in energy security, climate change mitigation, and economic benefits. A non-renewable resource (also called a finite resource) is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. These are used all over the world , in developing and non-developing countries to create electricity.
