Which of the following is NOT a property of water?
The Bonds holding together the atoms of a water molecule are polar covalent. The attractions between water molecules are hydrogen bonds.
Which of the following is not a property of water?
A. Solid water (ice) sinks when placed in water because water molecules pack more closely together as ice than when in the liquid form. This makes the solid more dense than liquid water. B. Water has high surface tension because of the hydrogen bonds between water molecules. C. Large heat capacity - it takes a lot of energy to raise the temperature of water by a little. D. Water makes a good solvent for polar substances because it too is polar.
Which of the following is NOT a property of bases?
1. Bases taste bitter. 2. Bases react with acids. 3. Bases feel slippery. 4. Bases produce hydrogen ions, H+, when added to water. 5. Bases make indicators change colors.
Which of the following is not a physical property of water?
I think it's c.
Which of the following is not a physical property?
Ability to catch fire is a chemical property. The rest are physical.
Which of the following is not a property of a basic solution? ANSWER QUICKLY!!!?
The answer is E. Acidic solutions usually taste sour where as the basic solutions will taste bitter. The definition of an acidic solution is that it will produce a higher concentration of H+ or H30+ ions when in solution with water. The definition of a basic solution is that it will produce a higher concentration of OH- ions when in a solution with water. So, therefore the basic solution will neither taste sour nor produce OH- ions.
Which of the following is NOT a property of acids? CHEMISTRY HELP!?
1) True, acids do react with bases 2) True, in general they form the H3O+ hydronium ion when in solution. Be careful, not all acids will give up their H+ as easily as others so the concentration of H+ in solution may vary, this is important for your second question. 3) False, acids don't form water with metals. If the acid is capable of reacting with the metal it is generally performing a redox (oxidation/reduction) reaction that usually produces H2 gas instead of water. 4) True, acids do have a sour taste but don't start tasting them. #2 First you have to realize if you are dealing with a strong acid or a weak acid. In the case of HCl you are dealing with a strong acid that will give up all of its H+'s no problem. This means that the concentration of HCl in solution is equal to the concentration of H+ in solution. Now we can calculate the pH. Just remember any thing with a small "p" in front of it means -log. So... in the case of pH all we are saying is -log[concentration of H+]. Just remember its the concentration of H+ not the acid. pH=-log[.006] pH=2.2
Which of the following is NOT a physical property of water?
It's B for the reasons others have listed.
