The correct answer from the choices is: D
Resonance is an event where an external force or vibration moves another system to oscillate with higher amplitude at certain frequences or there is a transfer of energy between two or more different storage modes.
Half life is determined using the equation expressed as:
A = Ao e^-kt
First, we need to find for the value k.
A = .67Ao = Ao e<span>^-k(33 min)
k = 0.0121
The half-life is then calculated as follows:
</span>A = .5Ao = Ao e<span>^-0.0121(t)
</span><span>t = 57.28 min
</span>
The answer is (3), oxidation occurs at the anode and reduction occurs at the cathode. That's because the oxidation reaction can lose electrons and reduction can gain electrons.
Answer:
I'm pretty sure the answer is B
Explanation:
Because when a chemical reaction takes place the substances atoms rearrange and turn into a different substance.
