Answer:

2. $\displaystyle S\:waves\:are\:also\:called\:secondary\:waves.$

1. $\displaystyle Ritcher\:scale$

Explanation:

2. Seismic waves vibrate from side to side and up and down. They go through solids only, travel slower than Pressure [or Primary] waves, which arrive second, and shake the ground violently.

1. A Ritcher scale senses the magnitude of earthquakes.

oksian1 [2.3K]

Answer:

The standard cell potential is 2.00 V

Explanation:

Step 1: Data given

Cu is cathode because of higher EP

Al3++3e−→Al E∘=−1.66 V anode

Cu2++2e−→Cu E∘=0.340 V cathode

Step 2: Balance both equations

2*(Al → Al3+-3e−) E∘=1.66 V

3*(Cu2++2e−→Cu) E∘=0.340 V

Step 3: The netto equation

2 Al + 3Cu2+ +6e- → 2Al3+ + 3Cu -6e-

2 Al + 3Cu2+ → 2Al3+ + 3Cu

Step 4: Calculate the standard cell potential

E∘cell = E∘cathode - E∘anode

E∘cell = E∘ Cu2+/Cu - E∘ Al3+/Al

E∘cell =0.340 V - (-1.66) = 2.00 V

The standard cell potential is 2.00 V
