Is this Question related to Chemistry?

Yep, it's to do with chemical bonding. If you happen to have the "Science Matters" textbook it's chapter 31 ("Chemical Bonding") which starts on page 219.

I don't know if this is right or wrong but I'll give it a try. I have a different textbook.:pac:

They are weak and they tend to be liquids or gases. They do not dissolve in water or conduct electricity.

- evaporation
- condensation
- precipatation
- run off/soakage

okies......

what is the symbol equation for plant respiration?

6 CO2 + 12 H2O + light → C6H12O6 + 6 O2 + 6 H2O
carbon dioxide + water + light energy → glucose + oxygen + water

I think...

Give a brief description of brown soils.

Daire10

Brown soil is the most common type of soil in Ireland.
It is located in places where deciduous trees once stood, as when the leaves fell off they decayed/ broken up by micro-organisms and earthworms, turning it into humus.
Thus brown soils are rich in humus & therefore, very fertile (suitable for a wide range of farming). Leaching is not common in brown soils & thus, no hardpan is present.

Or capillary action,can be said either way!

Ok, watch me go!Ahem
Capillary action is when the water that has been irrigated from a cooler climate to a hotter climate is soaked back up from under the soil by the sun,the water that has been evaporated by the sun leaves behind salt.Salt acts as a poison to plants and kills them!
