The type of nuclear decay in which Oxygen decays to form nitrogen is beta plus decay.
<h3>What is a beta plus decay?</h3>
A beta plus decay is a type of decay in which a proton in an element disintegrates to produce a neutron resulting in a decrease in the atomic number of the radioactive element.
In the given equation below:
Oxygen decays to form nitrogen due to a decrease in atomic number.
This is an example of beta plus decay.
In conclusion, oxygen decays to form nitrogen beta plus decay.

An element is a species of atom that has the same amounts of electrons and protons in their nuclei. To know which of these substances are elements, we can look it up in the periodic table of elements. The elements are as follows:
1.silicon
2.lead
3.silicone
5.iodine
where 
the Avogadro's constant that relates the number of particles to their number, in the unit moles 
.
The molar mass of propanol- mass per mole propanol- can be directly deduced from its molecular formula with reference to a modern periodic table.
of propanol molecules would thus have a mass of 
Answer:
0.21 M
Explanation:
Molarity is the calculation of the solution in which the number of solute per liter of the solutions. It is the most common measurement unit that is used to measure the concentration of the solution.
The molarity is the unit that is used to measure or calculate the volume of the solvent. The amount of solvent is used in the chemical reaction.
The amount of the two solvent in the same quantity is measured by the formula called c1v1 and c2v2.
