Answer:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
Hello!
This question requires a model -- you'll have to do that yourself. However, I can explain the steps for the process:
• Chlorophyll absorbs the sun's energy.
• The energy is used to split water molecules into hydrogen and oxygen.
• The oxygen is released from the leaves into the atmosphere.
• The hydrogen and carbon dioxide glucose (food) for plants.
If you have any more questions related to this assignment, please let me know!
Well , I will say this is a false statement.
This is because compounds which were all made by the same bond have same physical properties but different chemical properties.
Chemical Properties :
How do the subtances react with ( water, acid,alkaline, base , gas like oxygen, etc. )
Physical Properties :
- Solubility of those subtances in (water or organic solvent )
- Electric Conductivity
- Melting or Boiling Point
- Density
- Smell (exp : Ammonia has pungent smell , Esters has fruity smell)
The balanced equation would be:
2HCl + Mg(HCO3)2 —> MgCl2 + 2CO2 + 2H2O
Answer:
Electro negativity decreases down the group
Explanation:
One of the known periodic trends is that electro negativity decreases down the group but increases across the period. The electro negativity of fluorine is 3.98 on the Pauling's scale while that of bromine is 2.96. Hence the magnitude of charge separation and degree of partial positive charge on hydrogen in HF must be much greater than that of HBr to a large extent due to the significant difference in electronegativity in HF compared to HBr.
