Question
I will rate u 5 if u give me an explaination
What is the For the cell reaction 2Al(s) + 3Sn4+(aq) rightarrow 3Sn2+(aq) + 2Al3+(aq)? Al3+(aq)+3e- Al(s), E degree =-1.66V Sn4+(aq) + 2e- Sn2+(aq),E degree 0.15V -1.51V 0 45V 151V 1.81V 1.93 V Nuclides with too many neutrons to be in the band of stability are most likely to decay by what mode? Beta- fission Beta+ alpha electron capture Which of the following nuclear decay processes decreases the nuclear charge? Electron capture Beta emission Positron emission 1 only 2 only 3 only 1 and 2 1 and 3 Which of the following corresponds to the most rapid nuclear decay? t1/2 - 1.0 x 103 min k = 1.0 x 10-5/s k = 1.0 x 10-1/day t1/2 1.0 x 109 year k = 1.0 x 10-3/year What is the percent activity of a radioactive sample (relative to its original activity) that has undergone four half-lives of decay? 12.5% 3.13% 25.0% 6.25% 75.0%Explanation / Answer
E0 = 0.15+1.66V = 1.81 V
Electron capture as then neutrons are emitted
3 only
K should be max. so here C)
No/2^4 = 6.25%
