This quality is important because that makes water a good solvent (it can dissolve many things). Other polar compounds and ions can easily be dissolved in water because polar + polar = even distribution of charge, and ions have a charge, so it's attracted to the opposite charge on the water molecule. The ability of water to dissolve many solutions is essential in organisms. In the bloodstream, for example, sugars and other nutrients are dissolved so that the blood cells can carry it to cells in the body. If sugars weren't dissolved, they couldn't reach cells.
Vegetable oil is hydrophobic and there for is not water soluble but alcohol on the other hand is completely soluble with vegetable oil. 3. We know from observing the vegetable oil and water together that the relative density of water is greater then the density of vegetable oil because the oil will always recede to the surface of water. 4. Emulsification agents allow for two unbendable liquids to be combined, the detergent hold properties that both substances can in return blend with leaving detergent dissolving in both the water as well as the alcohol unlike other substances we tried to
1. Elizabeth Royte’s question “For now, what should we be drinking?” is answered throughout the excerpt by saying that tap water is no better than bottled water. Although bottled water labels say their water comes from the best of the best types of filter, its often a lie and comes from the same type of water that comes through your tap water, according to Royte. She supports her conclusion throughout the whole excerpt with specific example and evidence. Although she has a water filter in her tap water, she believes it is almost the same without one.
B) permanent dipoles of molecules containing covalent bonds between atoms of very different electronegativities. C) the hydrophobic effect. D) ion pairing between oppositely charged functional groups. Answer: A Page Ref: Section 5 28) The aggregation of nonpolar molecules or groups in water is thermodynamically due to the A) increased entropy of the nonpolar molecules when they associate. B) decreased enthalpy of the system.
This is done when we use the bathroom. Water also helps break down food in our stomachs. Without water it would be impossible for our body to break down the food that we eat and goes to our blood cells and that’s what gives us energy. There are also other reasons that our body needs water. Water also acts as a shock absorber for our eyes, brain and other vital organs.
Homeostasis can shut down causing imbalance of water, pH balance and ionic equilibrium, all factors of homeostasis in individual cells. F. Why was reestablishing oxygen flow to Joseph’s body so important? What processes would be affected by lack of oxygen? Without oxygen the cells would not work and ultimately die. All processes in the
(d) What evidence suggests that nitrate compounds are soluble in water? (e) Write the chemical formula for each precipitate that formed. Apply and Extend (f) Write a balanced chemical equation for each precipitation reaction that occurred. (g) Why is it necessary to use distilled water to prepare the solutions used in this investigation? (h) "Hard" water contains a high concentration of calcium ions.
Salt dissolves in water because ions become separated by polarised water molecules. Water is the most common molecule in the human body, and is the most important solvent in the human body and most chemical reactions involve molecules dissolved in
(S) – Well, there are some different points but surprisingly we share some things in common too. Some different points would be that humans use their bloodstream to get nutrients to their body, while we let the water filter and get rid of any unwanted waste by filtering out the osculum. Another point is that humans have much more digesting to do then sponges, they have to go through two spate processes a mechanical and a chemical digestion process while we just go through a single process. (I) - You said there were some things that you share in common as well? Could you please explain on those points?
MYTH! Drinking water will only absorb into your body which means water will only hydrate you. - Drinking lots of water leads to weightless. MYTH! It doesn't, it only leads to losing water weight.
