2) Match the operating state name to the correct operating state description. A. Active

B. Cutoff

C. Saturation

Match letter Operating State Description

In this region the collector and emitter diodes are both conducting. IC reaches a maximum value and VCE is approximately zero

Sometimes called the linear region. The emitter diode is forward-biased, the collector diode is reverse-biased. The collector current is approximately equal to the emitter current and base current is much smaller that either the emitter or collector current.

In this region neither the collector or emitter diodes are conducting. IC is approximately zero and VCE equals VCC

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
