+3
Hence, the magnetic behaviour of the complex is paramagnetic. The oxidation number of the central metal atom: The oxidation number of the metal iron is +3.
Answer:
D.) This atom has an atomic number of 50
Explanation:
A is wrong because we determine the type of atom by their number of protons, not the number of neutrons. This makes the atom Tin (Sn).
B is wrong because both protons and neutrons contribute to the weight of an atom, not just neutrons
C is wrong because the correct name for this isotope would be tin-119, which is calculated by adding the protons and neutrons
D is correct because isotopes of the same element always share the same atomic number
2NaCl + CaS → Na₂S + CaCl₂
Cars need more tire in the winter because of the low temperature which results to a lower pressure as well. This is base on the ideal gas equation where PV = nRT. Volume, number of moles and R are constant values. Pressure and Temperature has a direct relationship.
