Not all bonds are "created equal". From the following molecules, which one contains the most easily broken carbon to carbon bond
navik [9.2K]

Answer:

H3C—CH3

Explanation:

The strength of a bond is indicated by the value of its bond dissociation energy. Simply put, the bond dissociation energy is the energy required to break the bond.

Carbon forms single, double and triple bonds with itself. As a matter of fact, carbon atoms can link to each other indefinitely. This is known as catenation and has been attributed to the low bond energy of the carbon-carbon single bond.

The bond energy of the carbon-carbon single bond is about 90KJmol-1 while that of carbon-carbon double bond is about 174KJmok-1. The carbon-carbon triple bond has the highest bond dissociation energy of about 230KJmol-1.

Hence, it is easier to break carbon-carbon single bonds than double and triple bonds respectively, hence the answer.

For the balanced equation: 2H2S + 3O2 → 2SO2 + 2H2O
Irina-Kira [14]

Answer:

8 moles SO₂

Explanation:

To find the moles SO₂, you need to multiply the given value by the mole-to-mole ratio. This ratio, between O₂ and SO₂, is made up of the coefficients from the balanced equation.

2 H₂S + 3 O₂ -----> 2 SO₂ + 2 H₂O

12 moles O₂          2 moles SO₂
--------------------  x  ----------------------  =  8 moles SO₂
                               3 moles O₂
