It is the inverse relationship of Pressure and Volume of Boyle's Law that creates the pump - vacuum activity that allows for us to breathe.
The statements which best describe beta decay are: option 1, 2 and 4.
<h3>What is a beta particle?</h3>
A beta particle can be defined as an isotope which typically undergoes radioactive decay through the emission of a radiation with a -1 charge.
Based on scientific information and records from radioactivity, we can infer that the statements which best describe beta decay are:
- During beta decay, an atom of proton becomes a neutron and a positron.
- During beta decay, an atom of neutron becomes a proton and an electron.
- Beta decay releases energy.

The chemical formula of hydrocortisone valerate is C26H38O6. First, we determine the molar mass of the substance by adding up all the products of the number of atoms and the molar mass of atoms as shown below.
molar mass = 26(12) + 38(1) + 6(16) = 446 g/mol
Since, there are 26 atoms of carbon in each molecule, the mass of carbon in each mole is
mass of carbon = (26)(12) = 312
Obtaining the percent by mass of carbon,
% by mass of carbon = (312/446) x 100 %
= 69.955%
Thus, the percent by mass of carbon in hydrocortisone valerate is approximately 69.96%.
Correct. Its called noble gas configuration.
