A. The main system of transporting nutrients to the body's cells is through the blood stream. But once a nutrient arrives at a needy cell, it is still inside a blood vessel while the cell lies outside. The lack of nutrients inside the cell, and between the cell and the blood vessel, creates a concentration gradient between the blood vessel and the cell. Due to the lower concentration in the cell, the nutrient diffuses through the blood vessel wall and into the cell.

A. Be careful, be very, very careful. By definition, an acid is a substance in solution, usually an aqueous solution. What you are probably referring to are compounds that COULD be acids if they were dissolved in water, but until they are dissolved in water they aren't acids. Take HCl, for instance. As a gas, HCl is called hydrogen chloride. Only when it is dissolved in water does it become hydrochloric acid. The anhydrous liquid, commonly called "hydrogen acetate", HC2H3O2, or acetic acid, or ethanoic acid, doesn't take on acidic properties until it is dissolved in water. Then there is benzoic acid, C6H5COOH, which is a weak, organic acid, and it is a solid. === Follow up === For all of those responders who said that HCl is a "liquid [cont.]

A. An amalagam is a mixture of ANY two or more elements, wheras an alloy is a mixture of two or more METALS. 1-polar substances disolve in polar solvents 2- To distinguish between the solutions I would first heat each solution to a high BP so all liquid evaporates. If a substance is left it is the solid disolved in a liquid dolvent. I would then use boiling point to separate the remaining two solutions into fractions if possible so the one with two fractions, depending on BP will be the miscible one.

Boiling points of liquids?
Q. I have just read that liquids have different boiling points. Is there a safe way to demonstrate this at the fifth grade level? I downloaded a chart of liquids and boiling points-- but they looked like chemicals too dangerous for us to study at home-- it looked like something for chemistry students at the college level. Can we explore this at home with common substances, such as candy mixtures, etc.? Can you give examples of liquids we can use?

A. the best safe experiments you can do with is the differece of water itself with the introduction of salt. Water boils at 101 degrees calcius, add a little salt to the equation, and u'd get a boiling point of approx. 110 degrees calcius. Thats what i did.

Why, most exactly, do water molecules give up energy when they form hydrogen bonds with other water molecules?
Q. When water molecules form hydrogen bonds, when condensing from water vapour to liquid water for example, they give up energy in an exothermic reaction. What exactly is it about the molecules that is the cause of the energy release? Is it a change in the electrons bound to the hydrogen and oxygen atoms that are involved in the bonds? Do they jump to lower energy levels and give off energy as photons? Or is it another mechanism? Dr. Greg, thank you very much for your answer. It confirms what I thought. I'm now looking up atomic theory and valance shells to try to understand why these lowest energy states exist (I'll step when I get to quantum theory).

A. first two answers are completely wrong. either that or those guys are not getting the question. formation of hydrogen bonds, including all chemical bond formation will release energy. this is due to bonding electrons dropping to a lower energy level once they have settled in what we call a "bond". since the electrons go to a less excited state, they lose energy in the form of heat, kinetics or light.

Q. like a solid/liquid i can physically hold
Asked by Lorr C - Mon Jan 7 15:05:17 2008 - - 1 Answers - 0 Comments
A. In chemistry, Le Chatelier's principle can be summarized as: If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or total pressure, then the equilibrium shifts to partially counter-act the imposed change. One example is CO2 solvation in the soft drink. There is a equilibrium between the CO2 in the gas phase above the liquid and CO2 dissolved. Before you open the bottle, a high concentration of CO2 is in the soft drink. Once you open up the bottle, allowing CO2 to escape out the bottle, hence the CO2 pressure above the drink greatly reduces. According to the principle, the equibrium would shifted to release more CO2 into the gas phase. You may thus see bobblings in the drink due to fast CO2… [cont.]

A. If I recall correctly, LH2 doesn't 'flow' uphill (that would be impossible because of gravity), but it can 'creep' uphill due to a combination of its low viscosity and capillary effect. To see capillary effect, put a clear straw in a glass of water. You will see the 'meniscus' (the edges of the water level) in the straw distinctly above the level of the water in the glass. No 'flow' required. I've heard that liquid helium has a similar property.
