Boron trifluoride/Molar mass
67.81 g/mol
A. 0.12 (mol/L)/s
rate = 1 x 10-2 • 2^2 • 3
Answer:
False
Explanation: isotopes generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
Answer:
restrict population growth ( second choice).
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.
