In the Beats lab, you are observing the beat pattern formed by combining the oscillations from the two circuits on the oscilloscope. On one circuit, you turn the capacitor screw clockwise and notice that the beat period increases. As you continue to turn the screw clockwise you eventually observe the beats spread so wide they are no longer there and all you see is a single frequency oscillation. What has happened

the force required to move the cart is divided by three or 33.33 n.

  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
