What elements are present in glycerol?

The molecular formula of glycerol is C3H8O3. As such, one molecule of glycerol contains three carbon atoms, eight hydrogen atoms and three oxygen atoms. Glycerol is colorless, odorless and viscous, and is commonly used in pharmaceutical formulations. Each carbon atom has a hydroxyl group attached to it, and the hydroxyl groups are largely responsible for the solubility of the molecule in water.

What is the definition of ecological imbalance?

One of the most important challenges facing humanity is the disturbance in this ecological balance due to human activity. The rising human population and the consequent encroachment of humans into forests and other ecosystems are the chief causes of ecological imbalance.\nEcological imbalance can cause sweeping changes in the world. Eventually, all organisms are affected by ecological imbalance. Many species may be wiped out, and others may suffer irreparable damage due to an imbalance in the ecology.

What are the main constituents of the Jovian planets?

The Jovian planets include Jupiter, Saturn, Uranus and Neptune. They all feature a little different composition and chemical makeup, but none have much in the way of solid surfaces. All of these planets also contain dense cores and rotate much more rapidly than the other planets in the solar system. Each one of the Jovian planet also contains moon and rings. The other planets are referred to as "terrestrial" planets. Earth and Mars are the only two terrestrial planets that contain moons.

How does a petrol engine work?

Cars use a four-stroke combustion cycle, or Otto cycle, to convert gasoline into kinetic energy. The four strokes include the intake stroke, compression stroke, combustion stroke and exhaust stroke. The intake stroke starts the combustion process by allowing the engine to take in a cylinder-full of air and gasoline. After this process, air is compressed through the movement of the pistons in the engine. Upon compression, a spark plug emits a spark to ignite the gasoline and causes a controlled explosion in the cylinder. The resulting explosion causes the piston to move downward, which causes t..

How do you learn to call animals by listening to their sounds?

If you want to call birds, listen to the calls of the specific type of bird you want to attract, and then use your lips, teeth and tongue to try and make a whistling sound that closely imitates the bird's call. If you do not have any success with this method, try using a manufactured call.\nOne type of manufactured bird call is the hand call. A hand call works like a primitive woodwind instrument by vibrating a reed against a piece of wood called a tone board to create sound. Depending on how hard you blow, as well as the relative sizes of the reed and the tone board, a hand call can imit..

How do you prevent factory pollution?

Factory pollution affects the air, land and water and can have widespread, long-term consequences for the atmosphere and the environment. Carbon dioxide is one of the most harmful emissions released into the atmosphere through the burning of fossil fuels and is a major contributor to the greenhouse effect, according to the Global Post. Other emissions contribute to acid rain formation and the depletion of ozone in the atmosphere. In addition, it is reported by National Geographic that 70 percent of industrial wastes are dumped into the water table. Improved filtration systems are an example of..

What are some examples of Bernoulli's principle?

Bernoulli's principle states that an increase in the speed of a fluid medium, which can be either liquid or gaseous, also results in a decrease in pressure. This is the source of the upward lift developed by an aircraft wing, also known as the airfoil concept. The greater surface area on the upper side of an aircraft wing created by that side's convex surface requires the air to travel around it at a faster rate. This higher air velocity creates a lesser degree of air pressure on the top side of the wing compared to the flat bottom side. The difference in pressure accounts for the up..

What is the highest recorded wind speed?

The previous world record for highest wind speed of 231 mph was recorded at Mount Washington in New Hampshire. It was recorded in April 1931. A Doppler weather radar recorded a wind gust with a speed of 318 mph in 1999 during an F5 tornado in Oklahoma City. However, records by Doppler radar are not considered official.

Why do lights appear to flicker from a distance?

If the light source lies outside the atmosphere of the Earth, such as the stars and the planet, the term for the flickering effect is called "atmospheric scintillation." When the source of illumination is Earth-bound, the phenomenon is referred to as "terrestrial scintillation."Wind movements that are carrying schlieren flowing across an observer's line of sight causes the light fluctuations that are characteristic of the scintillation phenomena. Studies also show that relative humidity affects the intensity of terrestrial scintillation. As humidity increases, so does the effect of terres..

What are the five lobes of the liver?

In relation to size, the left lobe is smaller than the right, approximately one-sixth its size. It is located to the left of the falciform ligament above and the umbilical and ductus venosus fissures below. The right lobe is located to the right of the falciform ligament above, and the fissures of the gall bladder and vena cava below. Extending from the anterior edge, the quadrate lobe is a square-shaped lobe located in the anterior region between the fissure of the gall bladder on the right and the umbilical fissure on the left.\nThe liver serves as a filtering agent and gatekeeper for fluids..
