Aseries ac circuit contains a resistor, an inductor of 220 mh, a capacitor of 5.50 μf, and a generator with δvmax = 240 v operating at 50.0 hz. the maximum current in the circuit is 140 ma. a. calculate the inductive reactance.ω
b. calculate the capacitive reactance.ω
c. calculate the impedance. kω
d. calculate the resistance in the circuit. kω
e. calculate the phase angle between the current and the generator voltage.

Explanation:

The capacitive reactance is given by:

Now,  The inductive reactance is given by:

By the ohm´s law, the electrical impedance is:

So

The total impedance is:

(*)

Where X is the total reactance given by:

Let´s calculate the real part of Z using (*):

Finally the angle between the current and the voltage is equal to the impedance angle:

  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

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
