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),

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
