Discuss the nature of the bonding in the nitrate ion () no3 2 . draw the possible lewis resonance diagrams for this ion. use the vsepr theory to determine the steric number, the hybridization of the central n atom, and the geometry of the ion. show how the use of resonance structures can be avoided by introducing a de-localized p mo. what bond order is predicted by the mo model for the nuo bonds in the nitrate ion?

Think about how you can use le chatelier’s principle to find possible solutions to the design problem. describe at least two ways to increase the yield (amount) of ammonia based on this principle.

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?

When the chemicals iron sulfide (fes) and hydrochloric acid (hcl) are combined, bubbles appear from the mixture. 1. does the appearance of bubbles indicate a physical or chemical change? 2. why do the bubbles indicate this change? 3. what property is this?
