Answer:
Products are the species formed from chemical reactions. During a chemical reaction reactants are transformed into products after passing through a high energy transition state. This process results in the consumption of the reactants.

Answer:
moon
Explanation:
the moon's gravitational pull generates tidal force which affects earth's tides
Answer : The enthalpy change for the reaction, ![\Delta H_{rxn}=-85KJ](https://tex.z-dn.net/?f=%5CDelta%20H_%7Brxn%7D%3D-85KJ)
Solution : Given,
(1)
![\Delta H_1=-393.5KJ/mole](https://tex.z-dn.net/?f=%5CDelta%20H_1%3D-393.5KJ%2Fmole)
(2)
![\Delta H_2=-285.8KJ/mole](https://tex.z-dn.net/?f=%5CDelta%20H_2%3D-285.8KJ%2Fmole)
(3)
![\Delta H_3=-3119.6KJ/mole](https://tex.z-dn.net/?f=%5CDelta%20H_3%3D-3119.6KJ%2Fmole)
![\Delta H_{rxn}=?](https://tex.z-dn.net/?f=%5CDelta%20H_%7Brxn%7D%3D%3F)
Now we have to calculate the enthalpy change for this reaction by doing:
![2\times eq.(1)+\frac{1}{2}(eq.3)\text{[reversing equation 3 and dividing it by 2]}+3(eq.2)](https://tex.z-dn.net/?f=2%5Ctimes%20eq.%281%29%2B%5Cfrac%7B1%7D%7B2%7D%28eq.3%29%5Ctext%7B%5Breversing%20equation%203%20and%20dividing%20it%20by%202%5D%7D%2B3%28eq.2%29)
![\Delta H_{rxn}=2\times \Delta H_1+3\times \Delta H_2+(-\frac{\Delta H_3}{2})](https://tex.z-dn.net/?f=%5CDelta%20H_%7Brxn%7D%3D2%5Ctimes%20%5CDelta%20H_1%2B3%5Ctimes%20%5CDelta%20H_2%2B%28-%5Cfrac%7B%5CDelta%20H_3%7D%7B2%7D%29)
![\Delta H_{rxn}=2\times (-393.5)+3\times (-285.8)+(-\frac{-3119.6}{2})](https://tex.z-dn.net/?f=%5CDelta%20H_%7Brxn%7D%3D2%5Ctimes%20%28-393.5%29%2B3%5Ctimes%20%28-285.8%29%2B%28-%5Cfrac%7B-3119.6%7D%7B2%7D%29)
![\Delta H_{rxn}=-85KJ](https://tex.z-dn.net/?f=%5CDelta%20H_%7Brxn%7D%3D-85KJ)
Therefore, the enthalpy change for the reaction, ![\Delta H_{rxn}=-85KJ](https://tex.z-dn.net/?f=%5CDelta%20H_%7Brxn%7D%3D-85KJ)
Red because it has the highest visibility from a far distance
Answer: According to the Bohr model, atoms emit light because excited electrons are returning to lower energy states, emitting the energy difference. This energy always has a specific wavelength because the electrons can only exist in set orbits. ... An emission spectrum is the frequencies of light emitted from an atom.
