Question 1

The standard free energy of formation of AgI(s) is –66.2 kJ/mol. Δ for the reaction 2AgI(s) 2Ag(s) + I2(s) is:

–66.2 kJ
132.4 kJ
66.2 kJ
–132.4 kJ
None of these are correct.

Question 2

The standard free energy of formation of nitric oxide, NO, at 1000. K (roughly the temperature in an automobile engine during ignition) is 78.2 kJ/mol. Calculate the equilibrium constant for the reaction
    N2(g) + O2(g) 2NO(g)
at 1000. K.

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.

Did you know?

When blood is exposed to air, it clots. Heparin allows the blood to come in direct contact with air without clotting.

Did you know?

The heart is located in the center of the chest, with part of it tipped slightly so that it taps against the left side of the chest.

Did you know?

The first monoclonal antibodies were made exclusively from mouse cells. Some are now fully human, which means they are likely to be safer and may be more effective than older monoclonal antibodies.
