HOW DO YOU WRITE A BALANCED CHEMICAL REACTION COMPLETE W STATE SYMBOLS THAT CORRESPOND TO THE ENTHALPY?
HOW DO YOU WRITE A BALANCED CHEMICAL REACTION COMPLETE W STATE SYMBOLS THAT CORRESPOND TO THE Delta H of f for:
ammonia carbonate
and
mercury(1) phosphite
To write the balanced chemical reaction to find the enthalpy of any compound, first find out all the elements it is composed of. Then, write a balanced chemical reaction for the compound using the formulas for the natural states (that is, the state of the element in which ΔH = 0).
For example, lets take ammonium carbonate, (NH4)2CO3. It is comprised of N, H, C and O. So, the skeleton equation will be:
N2 + H2 + C + O2 —> (NH4)2CO3
Balancing, we get:
2N2 + 8H2 + 2C + 3O2 —-> 2(NH4)2CO3
Incorporating the states, we get:
2N2(g) + 8H2(g) + 2C(s) + 3O2(g) —-> 2(NH4)2CO3(s)
Using this reaction, we can find the enthalpy of formation for (NH4)2CO3. Follow a similar procedure for Hg3PO3. If you do that, you will get:
P4(s) + 12Hg(l) + 6O2(g) —-> 4Hg3PO3(s)
Hope this helps.

Carl Orff: Carmina Burana $7.74 Yes, here it is folks–that irritatingly catchy chorus you first heard in the film Excalibur, or as the background music to the HBO Boxing Specials, and in zillions of other places. What it’s not is the music from The Omen, which it clearly inspired. All pieces of music that feature choruses chanting in Latin are not the same (in fact, Stravinsky’s Symphony of Psalms is much closer to The Ome… |
