Does oxygen always have a negative charge? The covalent bonds are therefore polar, and the oxygen atoms have a slight negative charge (from the presence extra electron share), while the hydrogens are slightly positive (from the extra un-neutralized protons). How many positive charges are in oxygen? That make the charge experienced by the eighth electron […]
Why do the velocities increase with temperature?
Why do the velocities increase with temperature? The rms velocity is directly proportional to the square root of temperature and inversely proportional to the square root of molar mass. Thus quadrupling the temperature of a given gas doubles the rms velocity of the molecules. As the temperature of a gas is increased, the velocity of […]
What are similarities and differences between comets and meteors?
What are similarities and differences between comets and meteors? Yet despite their apparent differences, there are similarities between them. Both are relatively small objects that have their origins in interplanetary space, orbiting the sun. A few meteorites may actually be fragments of comets, although such fragments are more likely to burn up as meteors in […]
What are the rules for drawing resonance structures?
What are the rules for drawing resonance structures? When learning to draw and interpret resonance structures, there are a few basic guidelines to help. . There is ONLY ONE REAL STRUCTURE for each molecule or ion. The resonance hybrid is more stable than any individual resonance structures. Resonance contributors do not have to be equivalent. […]

Do all cells in our body have the same DNA?
Which layout is best when a hard to move product is produced?
Which layout is best when a hard to move product is produced? A fixed-position layout is appropriate for a product that is too large or too heavy to move. For example, battleships are not produced on an assembly line. When new products or services are being planned? When new products or services are being planned, […]
Which item is an essential amino acid?
Which item is an essential amino acid? Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Can you test for amino acid deficiency? Plasma amino acids is a screening test done […]
