Question 1

Find ΔH°rxn for the reaction
         CH4(g) + 2O2(g) → CO2(g) +  2H2O(l).
         [ΔH°f (CH4(g)) = –74.8 kJ/mol; ΔH°f (CO2(g)) = –393.5 kJ/mol; ΔH°f (H2O(l)) = –285.5 kJ/mol]


Question 2

Given the following ΔH° values,
         H2(g) + O2(g) → H2O(l)   ΔH°f = –285.8 kJ/mol
         H2O2(l) → H2(g) + O2(g)     ΔH°rxn = 187.6 kJ/mol
calculate ΔH°rxn for the reaction H2O2(l) → H2O(l) + O2(g),

Immunoglobulin injections may give short-term protection against, or reduce severity of certain diseases. They help people who have an inherited problem making their own antibodies, or those who are having certain types of cancer treatments.

Did you know?

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
