A scientist measures the standard enthalpy change for the following reaction to be \( -822.3 \mathrm{~kJ} \) :
\[
\mathrm{CH}
A scientist measures the standard enthalpy change for the following reaction to be \( 16.0 \mathrm{~kJ} \) :
\[
\mathrm{Ca}(\
A scientist measures the standard enthalpy change for the following reaction to be \( -822.3 \mathrm{~kJ} \) : \[ \mathrm{CH}_{4}(g)+2 \mathrm{O}_{2}(g) \rightarrow \mathrm{CO}_{2}(g)+2 \mathrm{H}_{2} \mathrm{O}(g) \] Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of \( \mathrm{H}_{2} \mathrm{O}(g) \) is \( \mathrm{kJ} / \mathrm{mol} \) 5 more group attempts remainine A scientist measures the standard enthalpy change for the following reaction to be \( 16.0 \mathrm{~kJ} \) : \[ \mathrm{Ca}(\mathrm{OH})_{2}(a q)+2 \mathrm{HCl}(a q) \rightarrow \mathrm{CaCl}_{2}(s)+2 \mathrm{H}_{2} \mathrm{O}(l) \] Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of \( \mathrm{Ca}(\mathrm{OH})_{2}(\alpha q) \) is \( \mathrm{kJ} / \mathrm{mol} \) 5 more group attempts remaining
