Solid ammonium iodide decomposes to ammonia and hydrogen gases at sufficiently high temperatures. NH 4 I ( s ) ⇌ NH 3 ( g ) + HI ( g ) The equilibrium constant for the decomposition at 400°C is 0.215. Twenty grams of ammonium iodide are sealed in a 7.50-L flask and heated to 400°C. (a) What is the total pressure in the flask at equilibrium? (b) How much solid NH 4 I is left after the decomposition?

Write the balanced molecular chemical equation for the reaction in aqueous solution for
mercury(I) nitrate and chromium(VI) sulfate. If no reaction occurs, simply write only NR. Be
sure to include the proper phases for all species within the reaction.

Deducing the reactants of a Diels-Alder reaction
n the molecule on the right-hand side of this organic reaction be made in good yield from no more than two reactants, in one
step, by moderately heating the reactants?
?
Δ
• If your answer is yes, then draw the reactant or reactants in the drawing area below. You can draw the reactants in any
arrangement you like.
• If your answer is no, check the box under the drawing area instead.

?
• Draw the major product, or products, of the reaction in the drawing area below.
• If there aren't any products, because no reaction will take place, check the box below the drawing area instead.
• Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are
enantiomers.
