The operation of hydraulic brakes in a car is based upon. principle. fill in the blank

It is based upon the principle of Pascal's law

Explanation:

As we know by the Pascal's law that when we apply pressure at any point of the fluid then that applied pressure is transferred to all points of fluid equally without any change in all direction.

In hydraulic brake system it will be same that occurs in the system. When we push the brake pedal then the pressure is exerted into the brake oil inside it

This pressure is transmitted by the fluid in all directions without any change or without any loss.

Now this pressure is exerted at larger area then due to this it will exert large force as we know that

Force = (Pressure)(Area)

So The operation of hydraulic brakes in a car is based upon the Principle of Pascal's law.

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
