Why might the presence of kudzu make it difficult for other plants to compete for resources?
Bingel [31]

Answer:

Kudzu kills trees and other plants by smothering and choking them with its fast-growing vines, and as the heavy vines engulf trees or shrubs their weight can actually break or uproot trees. A kudzu vine can grow as much as a foot per day and sixty feet during a growing season.

The total pressure of a mixture of oxygen and hydrogen is 1.00 atm. The mixture is ignited and the water is removed. The remaini
blsea [12.9K]

Answer:

molar composition of oxygen =0.2 (20%)

molar composition of hydrogen = 0.8 (20%)

Explanation:

Since hydrogen and oxygen react according to

2*H₂+ O₂ → 2*H₂O

according to the ideal gas law:

P₁*V=n₁*R*T (initial state)

P₂*V=n₂*R*T (final state)

dividing both equations

P₁/P₂ = n₁/n₂

then since 2 moles of hydrogen react for every mole of oxygen that reacts, thus oxygen that reacted "no" is

no =  (n₁-n₂) 1/(1+2) = n₁ (1-n₂/n₁)/3

then

molar composition of oxygen = xo= no/n₁ = (1-n₂/n₁)/3 = (1-P₂/P₁)/3 = (1-0.4 atm/1 atm )/3 = 0.2 (20%)

then

molar composition of hydrogen = xh= 1- xo = 0.8 (20%)

to verify it , the number of initial moles n₁=remaining hydrogen + hydrogen that reacted + oxygen that reacted

and since 2 moles of hydrogen react for every mole of oxygen that reacts n₁= n₂ + (n₁-n₂) (2/3) + (n₁-n₂) (1/3) = n₂ + (n₁-n₂) = n₁
