Answer:
[tex]9.276[/tex]
Explanation:
As we know that one kilo joules is equal to [tex]239.006[/tex] gram calories
Given ,
Energy required by thermal decomposition of rail car load of limestone to lime and carbon dioxide is equal to
[tex]7.92 * 10^6[/tex] Kilo joules
This kilo joules of energy is converted into calories and is equal to
[tex]7.92 * 10^6 * 239.006\\= 1.892*10^9[/tex]
On taking the log of this value, we get -
log ([tex]1.892 * 10^9[/tex]) [tex]= 9.276[/tex]
Hence, the answer is [tex]9.276[/tex]
