There are several gases commonly used for filling balloons, with the most popular being helium and air. Helium is lighter than air, allowing balloons to float, while air is typically used for ground decorations. Other gases like hydrogen can also be used, but due to its flammability, it is less common. In total, the primary gases for balloons are helium, air, and sometimes hydrogen, along with other specialty gases for specific effects.
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
Gases used are: air (and hot air), helium.

Trees take in more oxygen than balloons. Through the process of photosynthesis, trees absorb carbon dioxide and produce oxygen as a byproduct. Balloons, on the other hand, do not produce oxygen as they are typically filled with gases like helium or air.
There are no cows in a box full of balloons, as cows are animals and balloons are objects commonly used for decoration or celebrations.

The two types of air balloons are * One is lifted using heated gases. * Another one is lifted using unheated gases.

Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
Hydrogen, Helium
Two of the gases that are used to fly balloons are Hydrogen and Helium. Helium is the preferred gas because Hydrogen is very explosive. The Hindenburg disaster was caused by the ignition of the Hydrogen gas that filled it.
Balloons get smaller over time due to the slow escape of the gases inside the balloon, primarily helium or air. The molecules of these gases are small enough to pass through the porous surface of the balloon material, leading to deflation.
Heated air, like what you breath.
Gases used are: air (and hot air), helium.
If I am right in interpreting the question as "Are balloons normally filled with hydrogen and oxygen?", then the answer would be no. Although they can be, as both substances are gases, the majority of balloon are filled with air, a mixture of nitrogen, oxygen, carbon dioxide and other gases. If you mean the balloons that float, they are filled with helium
