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
Thank you so much sir.. Sir please can you help us to explain the rest of periodicity, s the way you explain ionization energy in one of your videos.. I really like Sir. Once again thanks
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
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
Hey Guys😀

Amen. keep sharing with friends
Welldone sir
So nice of you
Lovely
Keep it up 💪🏾
May GOD bless u sir❤
Amen. Keep sharing with friends
Quite interesting. We'll appreciate it if you treat some tricky topics in chemistry .
Alright anticipate
Sir do d one for ui
Thank you so much sir..
Sir please can you help us to explain the rest of periodicity, s the way you explain ionization energy in one of your videos..
I really like Sir.
Once again thanks
Sir please give us more exercise and explanation on pH and poH
Thank you sir❤❤
Most welcome
Sorry sir, please in radioactivity, which unit will they give the time in?
Seconds, Minutes or Hours?
Okay, let me explain

@@NurseBright yes sir.
Thanks alot
Does the -log matters in your calculation
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
Well done sir... pls sir does uniben have department cut off mark
Thanks. Yes the do
Sir can you do q viedo on Energetics ☺️☺️
Yes, soon
Sir please do a video on dimensional units
Alright ❤️
What is the difference if I jus divide the t nut over 2??
How did you get 14
Too much talking
