The total heat gained by the solution is: q = mc(dT), where m = 75.0 g H2O, c = 4.18 J/g-C, and dT = 31.8 - 23.2 = 8.6 C. This gives a value of q = (75.0)(4.18)(8.6) = 2696.1 J.
If there were 10.00 g of the compound, then the heat of dissolution of the compound is: 2696.1 J / 10.00 g = 269.61 J/g.
The reaction follows the normal rules for an acid-carbonate reaction, which in turn is a special kind of acid-base reaction.
Acid + Carbonate -> Salt + Water + CO2
(Citric Acid) + (bicarbonate soda) -> (<span>Trisodium citrate) + water + CO2</span>
This is a very fast reaction, which produces a lot of carbon dixoide in a very short amount of time, which is the bubbles that you see. The other chemicals produce are clear liquids, so you don't see any of them.
Answer:
Check the explanation
Explanation:
Taking a look at the image, I have shown only the energy levels and not the proper curves, because we just need to calculate the energy differences.
Here, S2 denotes a ground state molecule while S2* denotes an excited state molecule
The energy D1, required for dissociation of excited state molecule to 2 ground state atoms is -ve, which means no energy is supplied, rather energy is emitted by this spontaneous dissociation.
