An ion is an element that bears only one electric charge, either positive or negative. An isotope is an element with the same number of protons but a different number of neutrons. An electron is a negatively charged subatomic particle. A dipole fits the characteristics. Hence, the answer is B.
Answer:
C₄H₁₂
Explanation:
The empirical formula gives you your smallest whole number ratio for the elements in the compound. Find the molar mass using a periodic table. We have one carbon (12.01 g/mol) and three hydrogens (1.008 g/mol). Therefore our molar mass for the empirical formula is 12.01 + 3(1.008) = 15.034 g/mol. To find the molecular formula divide the given molar mass by the empirical formula's molar mass 60.2/15.034 = 4.004257017 = 4. This number is the amount to multiply the empirical formula by to get the molecular formula, therefore your molecular formula is C₄H₁₂
The answer is emission spectrum. It is the range
of frequencies of electromagnetic radiation produced because
of an atom or
molecule generating a transition from a high energy state
to a lower energy state. The photon
energy of the produced photon is equivalent
to the energy change between the two states. There are many conceivable
electron changes for each atom, and each change has a precise energy
difference.
