Answer:
C) atmosphere → plants → animals → soil
Explanation:
The third choice provides the correct path through which carbon is cycled in nature.
Carbon passes from the atmosphere to plants then to animals and finally to the soil.
- Plants uses carbon dioxide from the atmosphere to manufacture their food.
- The food is made up of giant carbon chains which also provides nourishment for animals.
- When animals digest plant matter, they obtain energy for their process.
- The waste is passed into the soil .
Ok so all are in the alkali family also they are all metals and in group 1 but I think the one that might reacts quickest is Li because it has less AMU
Yes. Baboons have larger brains than chimpanzees
Mass for carbon = 12
Mass for hydrogen = 1
Mass for oxygen = 16
Mass for nitrogen = 14
12+1+14+16 = 33
165g / 33g = 5
times all the atoms by 5
C5H5O5N5
Answer:
12.213 minutes will be taken for 120 g-Thalium-208 to decay to 75 grams.
Explanation:
Radioactive isotopes decay exponentially in time, the mass of the isotope (
), in grams, is described by the formula in time (
), in minutes:
(1)
Where:
- Initial mass of the isotope, in grams.
- Time constant, in minutes.
In addition, the time constant associated with the isotope decay can be described in terms of half-life (
), in minutes:
(2)
If we know that 
, 
and 
, then the time taken by the isotope is:
12.213 minutes will be taken for 120 g-Thalium-208 to decay to 75 grams.
