Suppose the half life of an isotope is 30 seconds and you have 10 grams to start with how much will you have after one minute

Hello!

The half-life is the time of half-disintegration, it is the time in which half of the atoms of an isotope disintegrate.

We have the following data:

mo (initial mass) = 10 g

m (final mass after time T) = ? (in g)

x (number of periods elapsed) = ?

P (Half-life) = 30 seconds

T (Elapsed time for sample reduction) = 1 minute → 60 seconds

Let's find the number of periods elapsed (x), let us see:

Now, let's find the final mass (m) of this isotope after the elapsed time, let's see:

I Hope this helps, greetings ... DexteR! =)

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

i believe the answer is three water molecules
