No because it is the valence electrons on the metals that can take/release energy in the form of light/heat.
There is no difference in the emissions if metal fluorides were used instead of metal chlorides. This is because the valence electrons on the metals are responsible for taking or releasing energy in the form of light or heat.
The emission of particles.
No, not likely and rather unknown to do so
A litter of two is not uncommon, though rather small. Fifteen is rather large. Expect 4-8 from a normal dog
Less cost effective than grid power, produce carbon emissions locally rather than further away.
Yes. People who expect things out of somebody, they tend to not care about their personality rather what they are expected of.
Pinatubo
As wild animals, I'd expect them to be rather gamy, though I've never actually eaten one.
Carbon compounds containing fluorine destroyed the ozone above Antarctica. This permitted a form of Ultraviolet light that kills many forms of life to reach the surface of the earth. Rather than have all life destroyed, nations got rid of refrigerants containing fluorides.
Forests absorb carbon dioxide (CO2) and store the carbon. A company or country emitting CO2 can plant trees to 'offset', or counterbalance their emissions. They may find it cheaper to do this rather than to reduce their emissions. Through afforestation they reduce their carbon footprint, and raise their standing among their peers.
They can be but a gift is something to show someone you care about them. You shouldn't expect one in return but rather be happy you are giving one.
You would expect to find a fold mountain range at a convergent or collision boundary rather than at a divergent boundary such as a mid ocean ridge.
