Why do they call it gasoline? In a lot of organic chemistry, -ene or -ine is used (think benzene/benzine), and so the part of the petroleum distilled-off and used in motor vehicles was the part of highest volatility, and in time was dubbed gasoline. Does liquid gas burn? Gasoline as a liquid does not burn […]
What increases atomic radius?
What increases atomic radius? Atomic radius decreases from left to right within a period. This is caused by the increase in the number of protons and electrons across a period. Atomic radius increases from top to bottom within a group. This is caused by electron shielding. Which element is most likely to attract electrons? Electronegativity […]
Is fluorescent light brighter than LED?
Is fluorescent light brighter than LED? Are LED lights brighter than or equal to Compact Fluorescent (CFL) bulbs? The trick is to understand the technology. In short, LED and CFL as technologies do not have a difference in brightness intrinsically. What type of light does the sun produce the most? ultraviolet rays What lumen is […]
What are the examples of liquid to gas?
Why do they call it a wheelbarrow?
Why do they call it a wheelbarrow? The term “wheelbarrow” is made of two words: “wheel” and “barrow.” “Barrow” is a derivation of the Old English “barew” which was a device used for carrying loads. The use of one wheel also permits greater control of the deposition of the load upon emptying. Who uses a […]
What are the quantifiable properties of matter?
What are the quantifiable properties of matter? They include properties such as color, length, volume, odor, and density. These properties are extensive if they depend on the amount of the substance being used or intensive if they do not depend on the amount of substance being used. What are the common properties of matter? The […]

What are the disadvantages of molecular orbital theory?
What are the disadvantages of molecular orbital theory? MO theory says that the electrons are delocalized. That means that they are spread out over the entire molecule. The main drawback to our discussion of MO theory is that we are limited to talking about diatomic molecules (molecules that have only two atoms bonded together), or […]
