Answer:
the cell will either
Explanation:
The hybrid atomic orbitals are formed by the combination of the valence orbitals on an atom. The hybrid orbitals formed have different energy and shape compared to the atomic orbitals that combine to form the hybrid orbitals. Hybrid orbitals help in explaining the shapes of the molecules and other bonding properties.
Therefore the correct answer will be,
b. A mixture of the valence orbitals in an atom
e. There are as many hybrid orbitals as there are valence orbitals that mix together.
f. Hybrid orbitals have a different shape and different energy than the atomic orbitals of which they are made
Answer:
2.13g
Explanation:
Atomic mass of CO2 = 12 + 32 = 44g/Mol
Atomic mass of C3H8 = 36 + 8 = 44g/Mol
Reaction
C3H8 + 5O2 --> 3CO2 + 4H2O
3CO2 = 6.39g
Required C3H8 = (6.39/(44 x 3)) x 44 = 2.13g
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.
