They are alike because they have the same numbers in a different order. One is reversing the numbers of the original set. They are different because one number is larger in value while the other is lesser in value compared to each other.
To determine the structure of the molecule, we add the number of atoms that is bonded to the central atom. In this case, we have 4 fluorine atoms bonded to the central atom, carbon. We then look at the one pair of electrons and then choose the correct arrangement. For this case, the correct shape would be a tetrahedral. Therefore, the bond angle would be 109.5 degrees.
2C3H7OH + 9O2 → 6CO2 + 8H2O
Answer is: because carbon(IV) oxide is released.
For example if baking soda is used for <span>the pizza dough, than on heat carbon(IV) oxide is product of chemical reaction:
2NaHCO</span>₃ → Na₂CO₃ + CO₂ + H₂O.
If we use yeast (<span>single-celled microorganism)</span>, also carbon(IV) oxide produced, because yeast turns sugars into carbon(IV) oxide.
