A Photograph enlarged to make a poster, the photograph is 10cm wide and 15cm high, The poster is 35cm wide, how high is the poster?

  52.5 cm

Step-by-step explanation:

Assuming the scale factor is the same in all directions, for poster height h, we have ...

  height/width = h/(35 cm) = (15 cm)/(10 cm)

  h = (35 cm)(15/10) = 52.5 cm . . . . . multiply by 35 cm

The poster is 52.5 cm high.

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.
