Why does ammonia hydroxide not react with calcium?
I'm not the best at chemistry just thought i would try to help. anyways I'm pretty sure its to do with how ammonia hydroxide cant break down the calcium for it to react. Full marks for trying. However, permit me to supply something a bit closer to the mark. ===================== I do not think the questioner has that question right. Ammonium hydroxide would react strongly with calcium, which is a reactive metal that bubbles hydrogen in contact with water. If you put some calcium metal in with ammonium hydroxide, it would immediately give off bubbles of hydrogen, and produce calcium hydroxide, releasing ammonia gas. I suppose that the question you really want to ask has something to do with why a dilute calcium hydroxide does not release ammonia from ammonium compounds. If that is what you want to know, the answer might be something like that calcium hydroxide is a weak base, too weak to displace the ammonium and produce ammonium hydroxide. I have my doubts though; that does not make much sense. I think you had better put more preparation into your homework. You cannot get anywhere in chemistry without taking trouble to understand it.
How can calcium hydroxide be used to test for carbon dioxide?
Calcium hydroxide can be dissolved to create a saturated aqueous solution, which is sometimes referred to as limewater. When carbon dioxide is bubbled through the limewater, the carbon dioxide reacts with water to form carbonic acid. The carbonic acid is first deprotonated to form a bicarbonate anion, which is then deprotonated once more to form the carbonate anion. The carbonate anion then reacts with a calcium cation to form calcium carbonate (the compound in limestone). Calcium carbonate is insoluble in water, and thus precipitates out. The formerly clear limewater solution has thus become cloudy, giving an indication that carbon dioxide is likely present. Reaction scheme is given below: CO2(g) + H2O --> H2CO3 H2CO3 + OH- --> HCO3-+ H2O HCO3- + OH- --> CO32- H2O CO32- + Ca2+ --> CaCO3(S) Note that if too much carbon dioxide is added or too little calcium hydroxide is used, then calcium bicarbonate will form instead of calcium carbonate. Calcium bicarbonate is water soluble, and thus will appear to produce a negative test.
How much lime milk do we need for neutralizing sulfuric acid that we will have pH 3?
To neutralize sulfuric acid with pH 3, you will need to calculate the amount of lime milk required based on its alkalinity. Lime milk typically contains calcium hydroxide, so you should determine the concentration of calcium hydroxide in the lime milk and use stoichiometry to find the quantity needed to neutralize the sulfuric acid. It's important to also consider the reaction stoichiometry and ensure that all acid is neutralized for a complete reaction.
What is better to use when removing outdoor odors lime calcium carbonate or hydrated lime calcium hydroxide?
Hydrated lime. It has been used for hundreds of years to deoderize everything from human wastes to animal wastes to decaying bodies. Calcium carbonate is simply ground up limestone, and although it is great for raising the pH of your yard or garden it doesn't do much to eliminate smells. Hydrated lime also has the advantage of being a dessicant (it absorbs moisture). M. Miller, Lime Specialist, U.S. Geological Survey
How much elements in calcium sulphate?
Calcium sulfate, or CaSO4, contains three elements: calcium (Ca), sulfur (S), and oxygen (O).
Can you wash your hair a day before you get a relaxer?
NOT, a good idea! Most chemical hair relaxers have sodium hydroxide as their main ingredient. Too much blood circulation at the scalp could cause the relaxer to burn your skin. Some relaxers have calcium hydroxide, which are much easier on the hair and scalp, but still if you have circulating blood at your scalp it can be painful. Of course, it depends on the person doing the relaxer too...along with the product and its strength! Make sure you choose someone qualified to do it professionally and correctly! This is a strong substance!
How much does calcium hydroxide has on a pH scale?
10
What is the best hair relaxer?
The best relaxers brand are up to you. There are some good relaxers but you need to get one that works well on your hair and hair type. Cocoa Keratin Kit is a good quality hair relaxer but in general no base chemical relaxers are the choice of Salons professionals because they are much more gentle on the hair and scalp.
How can you get emo hair without straightening?
just get a relaxer and a blow dryer that says BLACK BIRD on the blowdryer then wash your hair and get another relaxer and blow dry your hair and then dye your hair and get your round brush and brush it alot and put oil til straight but not to much oil you are so welcome and I'm 9years old and i hispanic
How much can you wash your hair after getting a relaxer?
3 days good for hair rehabilitation and sebum formation . . . If you wash it after, 30% chance of getting bald for the next 3 months

How much elemental Calcium is there in Calcium oxide?
There is no elemental calcium in calcium oxide. Calcium oxide is a compound made up of calcium and oxygen atoms bonded together. When calcium oxide reacts with water, it forms calcium hydroxide, which contains calcium ions but not elemental calcium.
To all You sister's out there could you please tell me If I can put a relaxer in my hair and then dye it black all in the same day?
NO!!! Your hair will fall out!!!! Relaxers have a lot of chemicals, and so do dyes. That is too much chemicals for hair to take in one day.....
How can calcium be poisoning?
Calcium is an important mineral that the human body needs; it is present in bones and has a number of other functions as well. However, calcium comes in a variety of forms, not all of which are equally beneficial to the body. Metallic calcium would react with water to form calcium hydroxide, a powerful base with a very high pH which can dissolve flesh. Even then, I would not describe calcium hydroxide as poisonous so much as corrosive, but it could be lethal in any event. There are also other calcium compounds which are poisonous, not because of the calcium but because of the other component of the compound, for example, calcium cyanide.
How do you get relaxer out of your hair?
Once you relax the hair, you can't strip it. You can't take it out. You've got to wait for it to grow out. You can try just curling it and seeing if the curl holds. But, pretty much once that hair's been relaxed, you have to wait for it to either revert or grow out.
If you perm your hair after taking down braids what will happen?
It depends on the health of your hair after taking the braids out. I would suggest waiting at least a week after taking out the braids for a relaxer. The braids add so much tention to the hair, the hair needs to breath a little before a chemical treatment. 6footlonghair.blogspot.com
How do you strip relaxer from hair?
Sorry to say...no there isn't and I know this from experience. You must let it grow out and ALWAYS condition during this process. I use a good leave in conditioner. If your hair is damaged and/or weak, braiding is NOT a good idea because of the stress it puts on the hair. Wash the hair regularly, air dry, and deep condition during this process. Patience is the key....
