I think the correct answer would be spontaneous oxidation-reduction reaction. The type of reaction in a voltaic cell is best described as a spontaneous oxidation-reduction reaction. A voltaic cell uses the energy from the chemical reaction involved to produce electrical energy. Hope this answers the question.
A. Of a given element have different numbers of neutrons
1 is an element, 2 is an compound
f = 40 Hertz
Explanation:
Velocity of a wave = frequency × wavelength
frequency = velocity/wavelength
20m/s = f × 0.50
20/0.50 = f
40 Hertz = f or f = 40 Hertz
