Answer:
Buy local and eat a more diversified diet including less meat and dairy to reduce your carbon emissions resulting from the use of fossil fuel-based fertilizers, pesticides, and gas required to produce and transport of the food you eat. Support clean energy sources.
Explanation: or
Alternatives to drivingWhen possible, walk or ride your bike in order to avoid carbon emissions completely. Carpooling and public transportation drastically reduce CO2 emissions by spreading them out over many riders.

![\large \boxed{\text{1.11 kg}}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B%5Ctext%7B1.11%20kg%7D%7D)
Explanation:
The buoyant force in kilograms is given by

Answer:
C. ↔
Explanation:
Resonating structure -
These are the set of lewis structures of the same compound .
Where the structure helps to show the delocalization of the electrons over the structure .
The charge on all the resonating structure remains the same .
All the structures can be interconverted to each other , and are shown by the arrow ↔ .
Hence , from the given information of the question,
The correct option is C. ↔
Answer:
The answer to your question is: D) 8
Explanation:
We can know the valence of an element if we know in which is located.
For example if an element is in group IA it would have 1 valence electron,
if an element is located in group IIIA it would have 3 valence electrons, if an element is located in group VIIA, it would have 7 valence electron and so on.
Neon is located in group VIIIA, so it would have 8 valence electrons.
