when the half-life is the amount of time which the radioactive isotopes need to
be in half.
So when w start with 32 g of unobtanium 53 so :
1- after 20 sec the number of grams remain = 32/2
= 16 g
2- and after 40 sec the number of grams remain
16 g will cut in half:
= 16 / 2
= 8 g
3- and after 60 sec the number of grams remain
8 g will cut in half:
= 8g /2
= 4 g
4- and after 80 sec the number of grams remain
4 g will cut in half:
= 4 g /2
= 2 g
5-after 100 sec the number of grams remain
2 g will cut in half :
= 2g /2
= 0 g
after 100 sec there are no grams remain
Answer is: hydrogen cyanide (formonitrile).
Anion CN⁻ is cyanide. Cyanide <span>consists of a </span>carbon<span> atom </span>triple bonded<span> to a </span>nitrogen atom (<span>C≡N).</span>
Hydrogen cyanide is colorless, poisonous liquid, <span>also weakly </span>acidic. Salts<span> of the cyanide anion are called cyanides.</span>
