$\text{C(graphite)}+\text{O}_2(\text{g})\overrightarrow{\ \ \ \ \ \ \ }\ \text{CO}_2(\text{g})$
During the reaction, temperature rises from 298K to 299K. If the heat superb, of the bomb calorimeter is 20.7kJ/ K, then what is the enthalpy change for the shove reaction at 298K and 1atm?$2\text{PbO}+4\text{HCl}\xrightarrow{ \ \ \ \ \ \ \ }2\text{PbCl}_2+2\text{H}_2\text{O}$
$\text{PbO}_2+4\text{HCl}\xrightarrow{\ \ \ \ \ \ \ \ }\text{PbCl}_2+\text{Cl}_2+2\text{H}_2\text{O}$
Why do these compounds differ in their reactivity?
