Problem 3: (15 points a lazy susan (a circular disk mounted on a vertical axle) is at rest at -0. it has frictionless bearings. texas sized cockroach of mass m starts center with velocity dp a) find the direction of spinning and moment of inertia of the lazy susan about the central axis (note that mass of lazy susan and its radius are not given). running counterclockwise around a circle distance d from the velocity of vo relative to the ground. as a result, the lazy susan starts spinning with angular top view axle wise spiuniu b) the cockroach finds a bread crumb and stops. what is the angular velocity of the lazy susan after the cockroach stops?

  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
