I was just wondering this after seeing the episode of Bones when they were trapped in the car. If you could put the chemical equation and why it reacts I would be very grateful because I have been trying to search for the answer on teh internet but haven't found anything?
The reason you haven't found anything on the internet is most likely due to this reaction being implausible.
I didn't see the episode, so I will have to assume that all the reactants were mixed together simultaneously. Lithium is a reactive metal that is solid at room temp. (it will lose electrons ie. ionize rapidly), sodium carbonate (Na2CO3) is also solid at room temp and will ionize into two sodium and one bicarbonate ions when added to water. Carbon dioxide is a gas at room temp and would dissipate into surroundings, not participating in any reaction.
Lithium + water alone would produce lithium hydroxide and hydrogen gas (which would also dissipate in surroundings), and lithium + sodium carbonate alone would produce sodium solid and lithium carbonate (which would ionize in the water solvent). Reacting all these simultaneously just doesn't seem to evolve oxygen gas no matter what!
(like...really quickly!) decomposes into water (H2O) and carbon dioxide gas (CO2): H2CO3 → H2O(l) + CO2(g) The gas formed produces nice, fizzy ...
H2SO4 + Na2CO3 = Na2SO4 + H2O + CO2
salt is sodium sulphate
is this a single displacement, double displacement, decomposition or synthesis?
i think it is a single displacement. is that correct?
Aussie Teen,
The reaction proceeds according to the following reaction:
NaHCO3 ---> Na2CO3 + CO2 + H2O
This is a decomposition reaction, as the sodium hydrogen carbonate (also known as sodium bicarbonate) is breaking down to smaller compounds (such as carbon dioxide and water).
Hope that helps!
start by writing out the species and the arrow.
NaHCO3 --------> Na2CO3 + CO2 + H2O
next note the 2 Na's on the right side. then balance Na
2 NaHCO3 --------> 1 Na2CO3 + CO2 + H2O
then balance CO3. you have two on the left. and 1 in the Na2CO3 on the right. means you need 1 more CO3 on the right. CO2 has 2 of the three O's leaves 1 for the H2O
2 NaHCO3 --------> 1 Na2CO3 + 1 CO2 + 1 H2O
finally check the H's. 2 on left 2 on right. al is well so the balanced equation is
2 NaHCO3 --------> 1 Na2CO3 + 1 CO2 + 1 H2O

sodium bicarbonate (NaHCO3) does indeed form sodium carbonate + carbon dioxide + water. it undergoes thermal decomposition above 60 degrees F to form the products of the above reaction. google thermal decomposition of sodium bicarbonate if you don't believe me.
another thing. not to be funny here but this is certainly a very straightforward general chemistry question. Arguing about the validity of the question without really thinking through the problem doesn't help this student.
water. (had to finish sentence.) Balancing equations are tricky!!! Please help!!

I tested the solution I made with my API test kit and it told me that it was 4 dkh. I figure it should be accurate enough for my purpose and I don't think having the exact target Co2 level is crucial. As a curiosity, I do have also some real commercial 4 dkh solution.

Soda Water For Weight Loss Demystified : Panic Attack Symptoms ...
Soda water is a alternative to sugar and calorie filled drinks when losing weight. Because obese people generally avoid plain water, it does not taste good enough when life circulate around good eating. Carbonated soda water taste great and when tired of the plain water, one can add Aromhuset flavours that hold no calories sugars or carbohydrates.
Soda water, or carbonated water, is also referred to as sparkling water , and is plain water to which carbon dioxide gas has been added. It is the number one ingredient of most “soft drinks.”. This process of carbonation has a happy result — carbonic acid, enjoyed by millions as soda pop.
By using a seltzer bottle filled with water and then “charged” with carbon dioxide, soda water (club soda) was produced in the past in the home. Club soda may be the same as plain carbonate water but it can have a small amount of table salts, and sodium trace minerals. Such additives sometimes make the taste of home made soda water somewhat salty. This process — naturally occuring in some areas — produces carbonated mineral water.
