18. have a nice day hope it helps.
Answer:
277.7 g of CO2
Explanation:
Equation of reaction
C13H18O2 + 11O2 ---> 13CO2 + 9H2O
From the equation of reaction
1 mole of ibuprofen produces 13 moles of CO2
Molar mass of ibuprofen is 206g
Molar mass of CO2 is 44g
13 moles of CO2 weighs 572g
Therefore, 100g of ibuprofen will produce (100×572)/206 of CO2
= 277.7g
Explanation:
I think it is the first option
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
