What are 3 examples of a chemical property? Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 2). Is size a chemical property? Any such characteristic of a material that […]

Is the phosphorus cycle fast?
Is the phosphorus cycle fast? Phosphorus moves slowly from deposits on land and in sediments, to living organisms, and than much more slowly back into the soil and water sediment. The phosphorus cycle is the slowest one of the matter cycles that are described here. How does the phosphorus cycle start? Phosphorus moves in a […]
What affects the EMF of an electrochemical cell?
What affects the EMF of an electrochemical cell? Electrochemical cells are different from normal reactions; however the amount of volts produced by the cell will be effected by the factors that affect chemical reaction rates. The main factors that affect chemical reactions are Temperature, Surface area and Concentration. How do you calculate cell EMF? Sample […]
Why is US East Coast colder than West?
Why is US East Coast colder than West? Land has a lower heat capacity than oceans, and it also heats and cools faster than oceans. During the winter, land is much colder than the oceans. When the westerly winds blow over it, the air cools substantially. Thus, the East Coast experiences extreme cold weather during […]
How many watts is a 10 hp motor?
Are cameras more accurate than mirrors?
Are cameras more accurate than mirrors? A mirror image is called a mirror image because it reverses things from left to right. You usually see a mirror image of yourself. In contrast, if you look at a normal camera photo, you see yourself as another person would see you. Mirrors are much more accurate than […]

How do you find weight with distance and work?
What is the principle of vibrational spectroscopy?
What is the principle of vibrational spectroscopy? When a sample is eradiated to a beam of incident radiation, it absorbs energy at frequencies characteristic to that of the frequency of the vibration of chemical bonds present in the molecules. This absorption of energy by vibrating chemical bond results in an Infrared spectrum. What is the […]
