How does vegetation allow greater infiltration?

Vegetation allows for greater infiltration by anchoring soil and keeping it from drying into a hard barren surface through protection from direct sun rays. When the soil is soft, infiltration is greatly enhanced.

Living and decaying roots  create a network of well connected channels in the soil called macro pores. Flow through these macro pores can be several hundred times faster than through the soil matrix.

Leaf litter produces humus. Soil structure is improved as soil particles are cemented together by humus and sugars excreted from roots.  The improved soil structure permits increased infiltration.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
