C) produce additional ER. D) undergo cell division. E) produce replacement lysosomes. 20) Rough endoplasmic reticulum A) contains ribosomes for protein synthesis. B) creates an enormous surface area for cell metabolism C) contains a compartment to transfer and modify products of metabolism D) all of the above 21) The function of mitochondria is
True or False: Liquid oxygen should have a larger surface tension than liquid bromine (assuming T and P are the same for both liquids). False: Surface tension of liquids increase as Intermolecular Force strength increases. Both O2 and Br2 are non-polar molecules, and have only dispersion forces. Those dispersion forces are stronger for Br2, however, since it has many more electrons (70 vs. 16) than does O2.
The structure shown above is oxygen's cubic crystal element structure. Oxygen exists in all three forms-liquid, solid, and gas. The liquid and solid forms are a pale blue colour. However, oxygen gas is colourless, odourless, and tasteless.The elemental structure is a cubic crystal shape. Oxygen changes from a gas to a liquid at a temperature of 182.96Â°C, and then can be solidified or frozen at a temperature of -218.4Â°C. Oxygen exists in all three allotropic forms.owever, oxygen gas is colourless, odourless, and tasteless. The elemental structure is a cubic crystal shape.
