Answer:

Option C: The solution begins to turn blue

Explanation:

When a copper wire is placed in a beaker containing a solution of silver nitrate(AgNO3), the copper (Cu) will reduce the positive silver ions (Ag+) to metallic silver (Ag). In this same process, Copper (Cu) is oxidized to produce Copper II ions (Cu2+).

The reaction will continue to progress and silver (Ag) crystals will begin to form on the Copper (Cu) wire and thus, we will observe that the solution becomes blue as a result of the formation of copper II (Cu2+) ions.

This is a single replacement reaction.

In an oscillating series RLCcircuit, with a 6.13 Ω resistor and a 15.2 H inductor, find the time required for the maximum energy
ivanzaharov [21]

Answer:

time for maximum energy is 1.718 sec

Explanation:

Maximum energy on the capacitor is given as  =\frac{q_{max}^2}{ 2C}

Maximum energy = \frac{(1/6) Q_2}{2C}

The maximum charge is given by

                                    q_{max} =Qe^{-Rt/2L}

                       Or\frac{q_{max}}{Q} = e^{-Rt/2L}

                    Orln\frac{q_{max}}{Q}  = \frac{-Rt}{2L}

solving for t

t = \frac{2L}{R}\frac{1}{2} ln( 2)

Putting all value to get desired value

 t = ln(2)\times \frac{L}{R}

 t = 0.693\times \frac{(15.2}{6.13} = 1.71 sec
