What kind of experiment would explain separation of salt water solution?
evaporation or boiling!!!
Explain fractional distillation and how it is used in refining oil?
Fractional distillation is a technique used to separate liquids with different boiling points. It is used in refining oil, whereby different types of oils are separated according to their different boiling points.
If the boiling point is recorded when bubbles are rapidly escaping the capillary tube.will the boiling point of liquid be recorded too high or too low explain?
If the boiling point is recorded when bubbles are rapidly escaping the capillary tube, it is likely to be recorded too high. This is because the presence of bubbles indicates that the liquid is already undergoing vigorous boiling, which can lead to superheating. Additionally, if the measurement is taken at a moment when vapor is escaping, it may not accurately represent the equilibrium boiling point of the liquid, which is typically determined under stable conditions.
Explain how the trends in melting and boiling poi?
Trends in melting and boiling points are primarily influenced by molecular structure and intermolecular forces. Generally, as molecular size increases, melting and boiling points rise due to greater van der Waals forces. Additionally, substances with stronger intermolecular forces, such as hydrogen bonds or ionic bonds, will typically have higher melting and boiling points compared to those with weaker forces. In the periodic table, melting and boiling points can also vary with group and period, reflecting changes in atomic size and electronegativity.
A cook decided to add salt to a pot of soup that was boiling on the stove. As soon as the salt was added the soup stopped boiling. Explain why this happened?
Adding the salt to the soup raised the boiling point of the water in the soup. This is a well known phenomena in thermodynamics that when you add a solute (especially one with a much higher boiling point than the solvent) to a solvent (which is water in this case) you will initially increase the temperature at which the resulting solution will boil - and incidentally also depress the temperature at which it will freeze.
How is stockholder's equity increased by revenues and decreased by expenses?
Briefly explain why the owner's investment and revenues increased owner's equity, while withdrawals and expenses decreased owner's equity
Explain why the boiling points of hydrocarbons that have the generic formula CnH2n plus 2 increase with molecular weight?
because the induced dipole-induced dipole forces are increased.
How can music relieve stress?
Levels of endorphins, natural pain relievers, are increased while listening to music, and levels of stress hormones are decreased. This latter effect may partially explain the ability of music to improve immune function
Explain why blackboards are not scratched by chalk but are scratched by the sand embedded in the chalk?
The hardness of sand is higher.
What kind of experiment would explain separation of salt water solution?

Explain how you could estimate the hardness of a mineral that does not appear on the mohs scale?
To estimate the hardness of a mineral not included in the Mohs scale, you could use a scratch test with reference minerals of known hardness. By attempting to scratch the unknown mineral with these reference minerals, you can determine its hardness based on whether it scratches or is scratched. Additionally, you could use more precise methods such as a microhardness tester, which measures the hardness under a specific load and provides a quantitative hardness value.
The plow revolutionized farming and increased production?
Explain ways the plow revolutionized farming and increased production.
What is the hardness of a mineral that scratches gypsum?
The mineral that scratches gypsum has a hardness greater than 2 on the Mohs scale. Gypsum has a hardness of 2 on the Mohs scale, so any mineral that can scratch it must have a hardness greater than 2.
Explain why mercury will need the most energy to boil?
Because it has the highest boiling point. -sorry if it is wrong-
Can you use the same multiplication fact to find 3 times 80 and 4 times 60 explain?
Yes because one number has been increased by a 1/4 while the other number has been decreased by a 1/4 So 3*80 = 240 and 4*60 = 240
Explain how liquids reach a point where they boil?
They 'reach' it by heating up the liquid till boiling point is reached.
