<span>Atoms are at their most stable when their outermost energy level is either empty of electrons or filled with electrons.</span>
Answer:
Explanation:
Resonance structure occurs in an organic compound that undergoes resonance effects. This resonance effect is sometimes called the mesomeric effect helps to increases the stability of organic compounds that have alternating single bonds and double bonds.
The second resonance structure diagram for the ion given in the question can be found in the attached diagram below.
In this question, you are asked the time but given the speed(89beat/min) and the number of beats(3.1 x 10^9). Then the equation would be:
Time= number of beats/ speed
Time = 3.1 x 10^9 beats / (89 beats/min)= 3.483 x 10^7 minutes.
Then convert it to years, disregard of leap years it would be : 3.483 x 10^7 minutes / (60 minutes/hour) / (24 hour/day) / (365 day/year)= 66.26 years
