An ant starts at -2 on the number line and travels east (positive direction) for 4 units then turns around and heads west (negative direction) for five units. it then travels east again for six units and to the west again for seven units. how far, total, does the ant travel?

(-2)  +  (4)  +  (-5)  +  (6)  +  (-7)  =  -4

Total distance traveled:  (Start position)-(End position) = (-2)-(-4) = 2

The ant travels a total of 2 units from its starting position. But traveled 22 units overall.

Hoped this helped!

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
