A gas occupies 5.6 liters at 0.860 atm. what is the pressure if the volume becomes 3.0L?

During cellular respiration, cells in the human body contribute to the generation of the weak acid, H2CO3. This reaction can lower the pH of the blood to dangerous levels. Fortunately, this acid combines with carbonate ions to form bicarbonate ions.

The diagram to the right shows energy for two reactions, A and B. Which reaction has the higher Gpx?. Which reaction has the higher activation energy?

How does a model make it easier for someone to understand the sun's and the moon's influences on the tides
