what makes bicarbonate soda react?
828596
It reacts when in contact with any acid material. When combined with an acid, it forms a salt.

Na2CO3 + 2HCl = CO2 + H20 + 2NaCl (aq)\n\nThis reaction is a double displacement reaction because oxygen from the sodium carbonate combines with the hydrogen in the hydrochloric acid to form water, and the sodium goes with chlorine to form sodium chloride, making carbon dioxide in the process.

Actually, that is a somewhat simplified reaction,\nin reality, the water and Carbon Dioxide dont form directly, they form after a secondary reaction (Carbonic acid decomposing).\n\n3Na2CO3 + 2H3PO4 --> 2Na3PO4 + 3H2CO3\nH2CO3 --> H2O + CO2\n\nSo combining them,\n3Na2CO3 + 2H3PO4 --> 2Na3PO4 + 3H2O + 3CO2

dilute hydrochloric acid reacts with the carbonate component of the limestone and the marble, and a few drops on the surface of the rock will 'fizz' allowing identification  (non carboniferous rocks such as granite will not give any reaction) . I dont know the exact chemical reaction, but I think hyrogen or maybe carbon dioxide is given off, hence the fizz ( gas bubbles)

Put some vinegar in a small soda bottle.  Use a straw with an end of it cut so it is like a spoon to put baking soda in a balloon.  Carefully place the end of the balloon on the top of the soda bottle working around the grooves of the bottle, but not dumping the baking soda in yet.  When you are ready, lift the balloon up so that the baking soda dumps into the vinegar, and watch the balloon inflate.  You just showed a chemical reaction.

NaHCO3(s) + CH3COOH(aq) → CH3COONa(aq) + CO2(g) + H2O(l) \nThis is the real chemical reaction.

Mentos is not very dense and has air pockets in it.  Soda has a low pH and is considered much more acidic than the mentos mint, which is basic enough such that it gets dissolved by your own saliva.  When acids and bases mix, fizzing bubbling usually occurs.  In this case, carbon dioxide builds up in a sealed 2 liter bottle of soda.  The gas is building up and trying to escape, and with help of a little agitation, it ends up bursting through the top of the bottle.

c since calcium carbonate  = CaCO3 and they react to produce calcium nitrate(Ca(NO3)2), carbon dioxide(CO2) and water(H2O).

well basically its just a chemical reaction.\n\nSince Soda is basically just made up of sugur,flavoring, water and preservatives. Since Mentos is a heavy peice of candy it sinks to the bottom of the coke bottle which making it easier for more bubbles to be formed from the bottom up. Each Mentos candy has thousands of tiny pits all over the surface. These tiny pits are called nucleation sites - perfect places for carbon dioxide bubbles to form. So thats what causes the eruption and boom it explode.

Anything, at this point... once you add something reactive to the cobalt, the reaction will turn reactants (cobalt and ____) into products, shifting the equillibrium.\n\nCobalt two has a positive-two charge.  You should add any ion with a negative-two charge: carbonate (CO3), chromate (CrO4), dichromate (Cr2O7), an oxide (O), sulfate (SO4), sulfide (S), or sulfite (SO3).

Carbonic acid formed by the CO2 in the soda.

My guess would be that since bicarbonate has a central carbon atom with an -OH group, a double bonded Oxygen atom, and a negatively charged oxygen attached, the resonance hybrid has effectively 2 carbonyl groups as the electrons from the O- atom can swing down to the carbon, making a double bond which kicks electrons up onto the other oxygen and back down and so forth.  Thus, it has 2 equivalent oxygens which are both partly a carbonyl group. 2 carbonyl groups gets shortened to bicarb- That's my best guess.

Bicarbonate of soda mixed into a glass of water. When you need to burp, let it rip.

Baking soda is sodium bicarbonate -- NaHCO3.\n\nIf you burned it, it would generate carbon dioxide (gas), water (vapor), and sodium oxide (solid residue).\n\nShould be no big deal.  Enjoy your bead making!

The fizz is a bunch of bubbles but they dont "explode" because of the static electricity in the hand. When the soda is made, you basically have a shit-load of carbonic acid in it. Carbonic acid is a fairly unstable substace. If you give it any reason, it will conver to carbon dioxide and water. so to keep it the carbonic acid form, the producers put a lot of preassure in the can. As soon as the can is opened a lot of the carbonic acid gets turned into carbon dioxide because you get rid of this preassure. This is evedent becasue you see the bubbles being formed when opening pop. All of the acid is not turned into CO2 though. Some of it get transformed due to the heat in the mouth (this is your fizz). if you stick a finger while pouring the drink, you are heating the pop thus creating the carbondioxide before it actually reaches your mouth. As a result you get to feel less amount of the fizz.

Vinegar is an acid (Acetic Acid) and baking soda is a base (Sodium Bicarbonate). Mixing acids with bases produces what is called "Acid Reduction Oxidation," or "Redox" reactions. Its basic forms result in salt (the type of salt is dependent upon the mixed chemicals), water, and heat (left over from the reaction). In the case of more complex reactions, where there is enough heat to separate some of the salt compounds, gases such as carbon-dioxide may alo be formed. \n\nThis is what creates the bubbles found in your "volcano."

No precipitate is formed.\nYou will see bubbles of carbon dioxide if there is enough HCI (Na2CO3+2HCI=2NaCI+H2O+CO2). If there isn't enough HCI ,Na2CO3+HCI=NaHCO3+NaCI happens ,you will see nothing.
