A = number of mass = 31 => number of protons + number of neutrons = 31
Phosphours, Z = atomic number = 15 = number of protons
Symbol of the element phosphorus = P
=> The symbol of the isotope is the symbol of the element, P, with the number of mass, 31, to the left, as a superscript, and the atomic number, 15, to the left, as a suscript.

Answer:
k = 3.2 x 10¹¹
Explanation:
The equilbrium taking place is:
- N₂(g) + 3Cl₂(g) ↔ 2NCl₃(g)
And the expression for the equilbrium constant <em>k</em> is
- k = [NCl₃]² / ( [N₂] * [Cl₂]³)
We are given all the required data from the problem, so now we <u>solve for k</u>:
- k = (1.9x10⁻¹)² / ( (1.4x10⁻³) * (4.3x10⁻⁴)³ )
Answer:
The volume of carbon dioxide gas produced can be measured using a gas syringe.
Explanation:
gas jar
Carbon dioxide is slightly soluble in water and denser than air, so another way to collect it is in a dry, upright gas jar. As the carbon dioxide falls out of the delivery tube and into the gas jar, it pushes the less dense air out of the top of the gas jar.
