Let's take potassium representing group 1.  All the others will do the same thing.  Here is the reaction:\n\n2K(s) + 2HCl(aq) --> 2KCl(aq) + H2(g)\n\nThe reaction for group 2 will be similar.  Let's take calcium  representing group 2:\n\nCa(s) + 2HCl(aq) → CaCl2(aq) + H2(g)\n\nHope this helps.

They are both excellent.  That said, Costco has a company-wide "hard" 9% cap on the markup of items.  That is, if an item costs them $100, the most they can sell it for is $109.  This even includes generic prescription drugs and furniture, two of the highest markup items one can purchase.  \n\nSam's Club has VERY reasonable prices that compete with (and frequently beat) Costco, but they have no official cap.  \n\nIn the long run, you're probably better off at Costco.

Hydroxyapatite is the material in the enamel of your teeth.  If you brush with a fluoride toothpaste, or get a fluoride rinse at your dentist, the fluoride ion in the rinse/toothpaste replaces some of the hydroxyl groups, converting the hydroxyapatite into fluorapatite.\n\nFluorapatite is a harder material, and more resistant to the acids caused by bacteria in your mouth.  This helps prevent cavities.\n\nHowever, it is important not to overdo the fluoride treatment -- excess fluoride ion in the body reacts with calcium (forming calcium fluoride), which screws up the electrolyte balance in your body, and can kill you.  This is why they recommend spitting out your toothpaste, rather than swallowing it.

The best calcium is that which occurs naturally in the foods we eat.  Brocolli, spinach, almonds, milk, cheese are great examples of calcium sources.  \n\nThe problem with supplements is their efficacy- some brands are more readily absorbed than others, and absorption can depend greatly on your individual body makeup.  Supplements are also an expensive way to admit you don't eat your veggies.

I believe that brand is alpha-factor. There are many other brands though they are all sized differently some of the ones i know are Gk, Snowflake, Motion Wear, and aplha-factor. I like gk they seem to be the best ones I could find in the 8 years I have been doing gymnastics. They are really sturdy and don't come apart as easy as some of the ones from other brands.

Magnesium my dear, magnesium.  It must be the correct type however.  There are certain cal-mag products that are fantastic.  Often sore/spasming muscles can be aleviated markedly with simply a very effective magnesium supplement.  Magnesium oxide is not particularly effective.  Magnesium citrate is better absorbed.  I don't mean to downplay the importance of Calcium.  Calcium alone will deplete the body of magnesium.  Many sports-medicine professionals recommend a 1:1 ratio of Calcium to Magnesium these days as there are SO many things in our modern society that simply deplete Magnesium.  Miss, please repond personally to me if you get or do not get results with what I have strongly suggested.  I would like to know results to better assist in the future both myself and others.  It is important to me that I give good usable information.  I believe I am.

Calcite...my favorite mineral!!! (Calcium carbonate, get it?)\n\nHardness is the most obvious. Calcite is 3 on Moh's scale. Quite soft! and quartz is 7.\n\nA penny, a nail or knife, a glass plate, all will help you separate these two. The quartz will scratch everything there. \n\nOne more test, that I didn't put on your other list that is the best test here, the acid test. A dilute acid will fizz when applied to the calcite, while the quartz will not react at all. This is why all good geologists carry around a bottle of acid in the field. Quartz (sandstone) and calcite (limestone) can be deceptively similar in appearance. \n\nThese two are good examples of why you cannot rely on just color or shape. Both quartz and calcite come in a variety of colors, depending on the impurity, and both can be completely opaque.(Think of rose quartz, milky quartz, amethyst, etc, and realize that calcite has as much variety) Both can be very similar crystal shapes since they are both in the trigonal system. Both have a white streak. Both have a glassy (vitreous) luster. \nCalcite:\nhttp://webmineral.com/data/Calcite.shtml\nQuartz:\nhttp://webmineral.com/data/Quartz.shtml\n\nThere is one more online resource I think you should look at:http://www.mindat.org/\nWebmineral.com is better for the questions you have asked, but mindat.org is very comprehensive and will have photos of more variations of the minerals that might help you understand the challenge of picking which properties are best for which minerals. On a lab test, you may be given samples to test that you have never seen, and they may be minerals you have seen before but in a different form (yes- its a trick), so knowing your tests can save you.\n\nBy the way, I just noticed your question about why color should be used with caution for identifying minerals. I think this answer is a good example of that. Many minerals come in many different colors due to some small impurity in the mineral. Both quartz and calcite come in almost every color of the rainbow. Fluorite is another good example of a mineral that can come in many different colors. Other examples are the many copper compounds which come in various shades of blues and greens. Because there are so many different copper minerals with the same color you can't use the color as a diagnostic for any one of them.

Do a search for 'barometers'\n\nAll I got was 'potassium tetraiodomercurate(II)' but I have never heard of and have no idea if thats what you are looking for ;O)
