The half life of this radioisotope is 12 hours.
<u>Explanation:</u>
The length of time it requires to break down for an initial half amount or the amount of time taken to transform half of a reactant into product. Half of a particular sample took the time to experience radioactive decay. The time it would take to degrade radioactively into another component or nuclide for half of the atoms of an unstable element or nuclide.
If 1/16 of the sample remains it predicts that there were 4 half-life periods then 16 = 2⁴
4 half-life periods = 48 hours / 4
half-life period = 12 hours.
Answer:
Electrons are located in an electron cloud, which is the area surrounding the nucleus of the atom. There is usually a higher probability of finding an electron closer to to the nucleus of an atom.

Its 1500 meters, which is equal to 0.9320568 miles. Hope this helps!
Explanation:
A molecule consisting of 100 amino acids has a molar mass
of 10,000 amu. The answer is letter A.
The role of the enzyme is to speed up biochemical
reactions. The answer is letter A. it does not take part in the reaction.
<h3>
Answer:</h3>
482.596 grams
<h3>
Explanation:</h3>
The relationship between moles, molar mass and mass of a compound is given by;
In this case;
The compound in question is P₂O₅
Molar mass of P₂O₅ = 141.94 g/mol
Rearranging the formula;
Mass = Moles × molar mass
Therefore;
Mass of P₂O₅ = 3.4 mol × 141.94 g/mol
= 482.596 grams
Therefore, mass of P₂O₅ is 482.596 grams
