Answer:
a b
Explanation:
I think so take it with a grain of salt
The major carbon sources (reservoirs that release more carbon than absorbed) are: deforestation and fossil fuels
The major carbon sinks (reservoirs that absorb more carbon than released) are:
soil, oceans and plants.
When scientists calculate the amount of carbon dioxide is returned to the atmosphere vs the released the amount of carbon, a large amount is unaccounted for and the total does not add up. This is why scientists believe there is an undiscovered carbon sink somewhere.

Explanation:
The valence electrons are electrons found on the valence (outermost) shell of an atom.
When an atoms form compounds, there is an exchange of valence electrons between the atoms of one element and the atoms of another element.
Let us consider a typical example, sodium has one valence electron and chlorine has seven valence electrons. This means that chlorine needs one electron to complete its octet while sodium needs to release one electron in order to attain the octet structure.
So, sodium gives out its one electron and becomes a stable sodium ion and chlorine accepts that electron and becomes a stable chloride ion. This is how the compound sodium chloride is formed.
Answer: carbon dioxide detector
The number of moles in 32.5g of aluminum chloride is approximately 0.250 moles.
