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
Hey there!
Given the reaction:
4 AI + 3O2 ------> 2 AI2O3
4 moles Al --------- 3 moles O2
9.30 moles Al --------- ?? moles O2
9.30 * 3 / 4 => 6.975 moles of O2
Molar mass O2 => 32.0 g
Therefore:
6.975 * 32.0 => 223.3 g of Oxygen
Hope that helps!
To do this problem it is necessary to take into account that the heat given by the unknown substance is equal to the heat absorbed by the water, but considering the correct sign:
