70×40 i need to no 70×40 can you me? ?

2800

Step-by-step explanation:

since 7 x 4 is 28 , 70 x 40 is 2800 because 70 is 7 x 10 and 40 is 4 x 10,

so 7 x 10 x 4 x 10 can be moved to get 7 x 4 x 10 x 10. if we do this we get 28 x 100 therefore 2800

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.

answer: it is 8

step-by-step explanation:

you know why its 8
