Explanation:
According to Bronsted-Lowry an acid is defined as the specie which is able to donate hydrogen ions when dissolved in water.
For example, 
On the other hand, bases are the species which are able to donate hydroxide ions when dissolved in water.
For example, 
In 
compound, when it will lose hydrogen ion then it will result in the formation of a 
(alkoxide ion). As the carbon atoms are donating their positive charge towards the 
ion so, it will become unstable in nature.
As a result, it will neither give a hydrogen ion or a hydroxide ion.
In 
, there is no difference in the electronegativity of both carbon and hydrogen atoms. Therefore, this compound is not polar in nature hence, it will neither give a hydrogen or hydroxide ion.
In 
there is presence of no -OH group. Hence, it will neither give a hydroxide or hydrogen ion.
Thus, we can conclude that none of the given compounds will act as an acid or a base.
We are given the equation 3CO(g) + Fe2O3(s)= Fe(s) + 3CO2(g) and determine the next step in balancing the equation. In this case,C is already balanced. The next step is to balance Fe so we put 2 before Fe (s) to balance the 2 atoms in the left of the equation.
