Knowing that volume is directly proportional to Kelvin temperature and that, in this situation, the final volume is double the initial volume, the final temperature (in Kelvin) should be double the initial temperature (in Kelvin).

Answer:
The first one would describe it best
Explanation:
The second option sounds like a single displacement reaction
The third is a decomposition reaction
ANd the first is a combination reaction
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms
4 steps of Carbon Cycle
Photosynthesis, Decomposition, Respiration and Combustion.
A = change in velocity / time
so change in velocity = 13-7 = 6
so 6/1 =6:
acceleration = 6m/s^2
Explanation:
a) 4P + 3O2 --> 2P2O3
b) The chemical reaction above limits the number of molecules of P2O3 produced for every 4 atoms of P.
