Answer : The molecule 
is a polar molecule.
Explanation :
Polar molecule : When the arrangement of the molecule is asymmetrical then the molecule is polar.
Non-polar molecule : When the arrangement of the molecule is symmetrical then the molecule is non-polar.
The given molecule is,
The electronegativities of oxygen and fluorine are different. The molecular geometry of is bent. As, Fluorine is more elctronegative than the oxygen. So, the arrows putting towards the more electronegative element i.e, fluorine. These arrows do not balance each other. Due to this, the asymmetrical arrangement of these bonds makes the molecule polar.
Hence, the given molecule is polar.
Answer:
A
Explanation:
The Charles law states that the volume of an ideal gas increases when temperature is increased under constant pressure. The pressure inside the balloon is always equal to the atmospheric pressure. Therefore answer A demonstrate the Charles law.

2) combustion reaction.
3) double replacement reaction
4) combination reaction
5) decomposition reaction
Explanation:
Chemical equation:
Fe₂CO₃ + 3C → 2Fe + 3CO
The given reaction is single replacement reaction. In this reaction carbon react with Fe₂CO₃ and replace the iron from CO₃²⁻ and form free iron and carbon monoxide.
Chemical equation:
C₂H₄ + 3O₂ → 2CO₂ + 2H₂O
The given reaction is combustion reaction. In which ethene burn in the presence of oxygen form carbon dioxide and water.
Chemical equation:
Fe₂O₃ + 6HCl → 2FeCl₃ + 3H₂O
The given reaction is double replacement reaction. In which anion and cation of both reactants exchange with each others.
Chemical equation:
2Al + 2Br₂ → 2AlBr₃
The given reaction is combination reaction in which aluminium and bromine combine to form aluminium bromide.
Chemical equation:
C₆H₁₂O₆ → 6C + 6H₂O
The given reaction is decomposition reaction in which glucose molecule decompose to give water and carbon.
