Chemistry Likely Questions with Detailed solution for 2024 Post UTME Examination

[@NurseBright]

Hey Guys😀
For QUESTION 3 On Radioactivity
Given(to) and Half life (t1/2) are both expressed in time units which can be seconds, minutes, hours, days, weeks, years. When solving any practice question at all you should have in mind that both of this parameters must be in same units when solving Questions. Like you can see in question 3 the value for given time(to) was 64 mins then when i solved for half life(t1/2) the answer gotten was still expressed in min. If the given time(to) in the question was in seconds the answer for half life(t1/2) will be in seconds
The same applies to all time units
Hope this is clear Now

[@Odumu_legend]

Thank you sir❤❤

[@NurseBright]

Most welcome

[@samuel_onyx]

Sorry sir, please in radioactivity, which unit will they give the time in?
Seconds, Minutes or Hours?

[@NurseBright]

Okay, let me explain
to and t1/2 are both expressed in time units which can be seconds, minutes, hours, days, weeks, years. In a particular practice question both of this parameters must be in same units when solving Questions. Like you can see in question 3 the value for given time(to) was 64 mins then when i solved for half life(t1/2) the answer gotten was still expressed in min. If the given time(to) in the question was in seconds the answer for half life(t1/2) will be in seconds
The same applies to all time units
Hope this is clear Now

@@NurseBright yes sir.
Thanks alot

[@Shimayam-cz2oy]

Does the -log matters in your calculation

[@patriciaomorodion5732]

Pls sir why didn't you use N1/No =(1/2)to/t1/2? You used 2 raised to the power of t initial over t half instead of 1/2 raised to the power of t initial over t 1/2. Pls reply

[@akinduroabiola6094]

Well done sir... pls sir does uniben have department cut off mark

[@NurseBright]
