WebWhich of the following could be the molecular formula of the compound? A) C2H2 B) C2H6 C) C4H8 D) C6H6 C) C4H8 -The balanced chemical equation is C4H8 + 6 O2 4 CO2 + 4 H2O, so combustion produces CO2 and H2O with a mole ratio of 1 to 1, in agreement with the observed equimolar ratio. WebIonization energy is the amount of energy necessary to remove an electron from an atom. The ionization energy tends to increase from left to right across the periodic table because of the increase number of protons in the nucleus of the atom. It tends to decrease down a column of the periodic table because the number of electron shells is larger, making …
