Half Life Chemistry Problems - Nuclear Radioactive Decay Calculations Practice Examples

Thanks man. Really.

Thank you so much you have no idea how much this helped 🥰

This was helpfull! My proffesor (Dr. Isaac kleiner)
Made me have to calculate it with barney and gordon, But i didnt understand any off it, i heard he was talking about teleporters and stuff.

why did you divide it by -35 and not 35 in the last problem? does anyone know?

❤❤

Brilliant explanation - how about this. I had 370MBq of I-125 on 26 Mar. How much did I have on 16th Mar? Help please

Infact this man is indeed a professor. I really like his teaching. How can a teacher make a one week or one month topic just turn into 18minutes?This man is very awesome.

im not sure why in the last problem you divided 35 into 7 ... I thought 7 was the. half life ????

100*(1/2)^5
ANS/100
.03125
1/32

No ones gonna see this but faster way for the first problem have 32 by itself times it by 1/8 you get 4 right. Then your gonna take 200 and times it by 1/2 to the 4th and thats how you get 12.5 faster

Have a good day (I have finals next week)

Sir your explanation is awesome and so vivid....Thanks a lot

How to get the natural log of 2 ( help my exam is tomorrow))

شرحح ممتاازز !!thanks keep going 💪

Thank you sir

In day of wed ,26, June 2024

Bro you know you are life saver

It's not giving me the answer...it's saying syntax error

I'm a little confused
The formulas are mixed up in my head

Who is watching in2025😅

why can't we take the half life constant devide it by the days, than divide the square of the days with the initial quantity of of the element to derive the final quantity?

Can someone tell me what In2 on the TI 2s calculator and used for what? I’m trying to break it down and grasp the concept of conversions, etc

Very good tutor, I can understand his explanation very well

you saved my life, literally!!!

wish I could know you are not teaching only organic chemistry but everything, before I fail my inorganic chemistry subject in my Second year BSc 2023😪😪😪 Now I'm in love with this subject and gonna sit for the exam in two days. good luck sir! you deserve better all the time

Who else has a test tomo🖐🖐🖐

I really love this lesson

i dont even listen to my chem teacher, he has it all...

Thank you

You single handedly saved my life

How did he punch on the calculator. How to write 200e 😥..anyone to explain

2024 students ?

HELLO SIR HAVE A GOOD DAY CAN YOU SOLVE THIS PROBLEM? CAUSE MY TEACHER AND I DIFFERENT ANSWER AND FOR ME MINE IS MY RIGHT ANSWER BUT I CAN'T EXPLAIN IT CLEARLY. AND I WHAT TO SEE YOUR ANSWER IN THIS PROBLEM SIR .

A radioactive sample contains 3.25 × 10^18 atoms of a nuclide that decays at a rate of 3.4 ×10^13 disintegrations per 26 min.

a. What percentage of the nuclide will have decayed after 159 days?

b. What is the half-life of the nuclide?

HOPE WILL NOTICE 🙏 Thank you sir ❤

great i learnt alot in this. mant thanks

how does bro know everything

For the final problem, im confused the -4.85/-35=-k, the answer should be negative why was k positive?

🤯🤯

great video, thank you

I don't understand why they don't teach this method in school
They will just be stressing my brain anyhow
Thank you very much The organic chemistry tutor

my teacher who graduated from breaking bad speedran the full of radiation in 1 hour and barely mentioned half lifes

Thanks king☺️☺️

No matter how much someone explains I’ll never understand this

Why am I getting this for homework in 8th grade 😭🙏

I came here from a SleepToken song reference, stayed for the lesson. Thank you!

My favourite tutor

where is the e on the calculator

in national exam we dont use techniques but we use formula so always use formula then use any other styles .

Nah this one is ass, like it's convient that the original amount is divisible by the remaining amount. Is there no formula for calculating half life? I love all of your videos but this is shit
