Answer:
Thermal decomposition or cracking
Explanation:
Petroleum is a mixture of hydrocarbons which are usually formed naturally. Petroleum undergo a host of chemical reactions. One of such is thermal decomposition or cracking.
Cracking is used in the petroleum industry to covert heavy fractions to more useful lighter ones.
When petroleum is subjected to high temperature and pressure, and in the presence of catalyst, the long chain type of petroleum will decompose into more useful smaller and lighter molecules.
Example is given below:
C₁₅H₃₂ → C₈H₁₈ + C₃H₆ + 2C₂H₄
Answer:
C!
Explanation:
only C
A: solid B: liquid : C: GAS
V1 / T1 = V2 / T2
3.5 / 20 = 3 / T2
T2 = 17.1 C
Answer:
Applying this same method to the carbonate ion, we have 3 resonance structures with bond orders of 2, 1, 1 when considering the bond between carbon and a single oxygen.
Explanation:
CO32- has three resonating structures. The way to calculate the bond order for most conpounds having resonating structures is:(No.of bonds/No.of resonating structures) Since, CO32- has 4 bonds, Thus answer will be 4/3 or 1.3333..
