Therefore carbohydrates are covalent compounds. Since electrons or more specifically valence electrons from their respective atoms are shared to form chemical bonds and acquire greater chemical stability from the bonds, this is present through out this biological macromolecule and is thus covalent.

Hey there!
A half-life means after a certain amount of time, half of that substance will be gone/changed after that time.
How many half-lives are in 16 days?
Multiply 16 by 24 (to get the total hours) and divide that by 2.5.
That is 153.6 half-lives.
35(0.5)^(153.6) represents the equation for this.
Simplify this and get 8.88 x 10^(-45).
There will be 2.02 x 10^(-45)g of germanium-66 sample remaining after 16 days.
Hope this helps!
