It is an isotope of Calcium, which has the symbol Ca
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.
Answer:
because water vapor condenses higher in the atmosphere,
Explanation: hope this helps you have a nice day
Answer:
95.9 kg
Explanation:
First we <u>convert 15.0 mi² to m²</u>:
- 15.0 mi² * (
)² = 3.88x10⁷ m²
Then we <u>convert 27.0 ft to m</u>:
- 27.0 ft *
= 8.23 m
Now we <u>calculate the total volume of the lake</u>:
- 3.88x10⁷ m² * 8.23 m = 3.20x10⁸ m³
<u>Converting 3.20x10⁸ m³ to L</u>:
- 3.20x10⁸ m³ *
= 3.20x10¹¹ L
Now we <u>calculate the total mass of mercury in the lake</u>, using the <em>given concentration</em>:
- 0.300 μg / L * 3.20x10¹¹ L = 9.59x10¹⁰ μg
Finally we<u> convert μg to kg</u>:
- 9.59x10¹⁰ μg *
= 95.9 kg
