Ans: Moles of CO2 = 0.25 moles
<u>Given:</u>
Mass of CO2 = 11 g
<u>To determine </u>
Moles of CO2
<u>Explanation:</u>
Moles = mass/molecular mass
Molecular mass of CO2 = 44 g/mol
Moles of CO2 = 11 g/44 g.mol-1 = 0.25 moles

Based on location in the periodic table, fluorine (F) has chemical properties that are most similar to iodine.
In the periodic table, elements are classified in groups and periods. The elements in the same group are chemically similar and they have the same number of valence electrons. Elements in the same period have the same highest energy level.
Hence, when looking for an element that is most chemically similar to iodine, we have to consider the element that is in the same group with iodine.
Both fluorine are iodine are both in group 17 hence, fluorine is most chemically similar to iodine.
