Answer:planting more trees
Explanation:
Trees go through photosynthesis and uses carbon dioxide (CO2) and changes it to oxygen
Answer:
.Electron affinity is -142 kJ<---------->O(g)+e−→O−(g)Process involves single electron addition
O−(g)+e−→O2−(g)<--------> Electron affinity is +710 kJ. .Process is endothermic
Cl(g)+e−→Cl−(g)=Electron affinity is -349 kJ. Process involves single electron addition
None of the of thee reactions ----------Electron affinity is +142 kJ.
Explanation:
Negative electron affinity values indicate that energy is given out when the atom accepts an electron. Halogens evolve a large amount of heat on forming halide ions.
Substantial amount of energy is absorbed when two electrons are added to O2- thus its electron affinity has a positive sign. Energy is evolved on adding only one electron to form O- is hence it has a negative value of electron affinity as shown.
<span>We can use an equation to convert from Celsius to Fahrenheit. Let F be the temperature in Fahrenheit and let C be the temperature in Celsius.
F = (9C / 5) + 32
F = (9 x 39.0 / 5) + 32
F = 70.2 + 32
F = 102.2 degrees Fahrenheit
The temperature is 102.2 degrees Fahrenheit.</span>
