Need help with this ASAP Anthony has a sink that is shaped like a half-sphere. The sink is 660pi in.^3. One day his sink clogged. He has to use one of two cylindrical cups to scoop the water out of the sink. The sink is completely full when he begins scooping.

part a) 13 scoops

part b) 3 scoops

Step-by-step explanation:

1) so we know that the volume of the sink is 660pi in^3

we have to divide this with the volume of each cup to find out the number of scoops it takes to get all the water out.

since we are dividing, I don't like leaving answers in terms of pi so

660*pi= 2073.45115137

formula for volume of cylinder(diameter)

pi*(5/2)^2*h=157.079632679

so

2073.45115137/157.079632679= 13.2 - for cup 1

for cup 2:

pi*(10/2)^2*8= 628.318530718

so

2073.45115137/628.318530718= 3.3- for cup 2

Hope this helps!

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.
