Answer:
A typical carbon carbon bond requires 348 kJmol to break What is the longest from ... wavelength (in nm) of radiation with enough energy to break carbon-carbon bonds? ... and radiation with shorter wavelengths can damage biological molecules because they carry enough energy to break bonds within the molecules.
Explanation:
Ultraviolet radiation and radiation of shorter wavelengths can damage biological molecules because these kinds of radiation carry enough energy to break bonds within the molecules. A typical carbon -carbon bond requires 348 kJ/mol to break.
A. When two chemicals mix their temperature rise: <span>Exothermic
b. </span>A solid burns brightly and releases heat, light and sound: <span>Exothermic
c. </span>When two chemicals are mixed their temperature drops: <span>Endothermic
d. </span>Two chemicals will only react if you heat them continually: <span>Endothermic
e. </span>Plants take in light energy for photosynthesis: <span>Endothermic

Answer:
A.) Adding more of gas C to the system
Explanation:
A.) is correct because the reaction wants to keep the same amount of reactants and products that sustain equilibrium. If you are increasing the amount of gas C, this will push the reaction to make more of the reactants to restore the balance.
B.) is incorrect because heat is a form of energy. As previously stated, when you add more material to the reactants side, the equilibrium shifts to the product side to restore equilibrium.
C.) is incorrect because when the volume is increased, the equilibrium will shift to the side with the greater amount of moles of gas. There is 1 mole of gas on the reactant side (from A (g)) and 3 moles of gas on the products side (from 3 C (g)). Therefore, the reaction will shift to the product side.
D.) is incorrect because if the material on the product side is decreasing, the equilibrium will want to make up that difference by shifting to the product side.
Remember,
reactants ---> products
Answer:
C
Explanation:
I really not sure if im wrong please tell me the answer and ill change it for other people
Have a great day! <3
The overall enthalpy of reaction will be calculated from enthalpy of formation of products and reactants.
DeltaHrxn = [Sum of enthalpy of formation of products] - [sum of enthalpy of formation of reactants]
DeltaHrxn = 3 X deltaHf (H2O) - [ 3 X DeltaH (H2) + DeltaH (O3)]
DeltaHrxn = 3 X (--242) - [ 0 + 143] = -869 kJ / mole
We can also calculate the enthalpy of reaction from bond energies
