True. The balanced equation: 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O represents the combustion of ethane (C₂H6).
A substance (often a hydrocarbon) combines with oxygen (O₂) in a combustion reaction, resulting in the major byproducts of carbon dioxide (CO₂) and water (H₂O). According to the equation, four molecules of carbon dioxide (CO₂) and six molecules of water (H₂O) are produced when two molecules of ethane (C₂H₆) and seven molecules of oxygen (O₂) react.
The number of atoms in each element is equal on both sides of the reaction arrow, indicating that the equation is balanced. This guarantees that the law of conservation of mass—according to which, in a chemical reaction, mass is never created nor destroyed—is upheld.
In conclusion, the combustion of ethane is accurately represented by the following balanced equation.

2C2H6 + 7O2 → 4CO2 + 6H2O
C2H6 is ethane,
Ethane reacts with oxygen, so it is the combustion.
The equation is balanced.
Answer is True.
Answer:
THE ANSWER IS THE DESERTS IF UR DOING USATESTPREP HINT THINGY
Explanation:
If it is three moles of NaOH i.e 3 NaOH
The number of atoms in each mole = 3 moles atoms
so total moles of atom = 9 moles of atom
in each mole of atoms = 6.023 X 10^23 atoms
so total atoms in three moles of NaOH = 9 X 6.023 X 10^23 atoms
= 5.4207 X 10^24 atoms
B) Can survive without sunlight
C) Can survive with little water
D) Flat leaves for floating in water
