My main reason would be momentum – it depends on the mass as well as the speed of the colliding objects. For example if two sedans travelling in a low speed bump each other, then probably the damage would be minimal scratches. However, if a high speed car crashes unto a heavy truck also travelling fast, then the result would be catastrophic.

Consider the reaction cl2(g) + i2(g) <=> 2 icl(g), which is endothermic as written. what would be the effect on the equili
bogdanovich [222]

The given equilibrium reaction is,

Cl_{2}(g)+I_{2}(g)+Heat2ICl(g)

According to Le Chatelier's principle states that when a system in equilibrium is disturbed by varying conditions like concentration, pressure, and temperature of the system, the system tries to counter act the affect by shifting the equilibrium towards the required side.

When Cl_{2} is removed from the system, the concentration of chlorine (Cl_{2}) decreases, the equilibrium is disturbed. So, the system tries to re-establish the equilibrium by moving in that direction which produces more of chlorine, that is towards the reactant side.

The correct answer would be: 1. reaction would go to the left, making more "reactants"

We would like to estimate how quickly the non-uniformities in gas composition in the alveoli are damped out. Consider an alveolu
Vera_Pavlovna [14]

Answer: It will take 11.775 seconds.

Explanation: As a sphere with a diameter of 0.1 mm, the area of an alveolus is

A = 4.π.r²

r for an alveolus would be: r = 0.00005m or r = 5.10^{-5}m

Finding the area:

A = 4.3.14.(5.10^{-5})²

A = 3.14.10^{-8}m²

The concentration change is to be 90% of the final, so

c = 0.9.3.14.10^{-8}

c = 28.26.10^{-9}

The oxygen diffusivity is 2.4.10^{-9}m²/s, that means in 1 second 2.4.10^{-9} of oxygen spread in one alveolus area. So:

1 second = 2.4.10^{-9}m²

t seconds = 28.26.10^{-9}m²

t = \frac{28.26.10^{-9} }{2.4.10^{-9} }

t = 11.775s

For a concentration change at the center to be 90%, it will take 11.775s.
