Question

1. What is the balanced equation that represents the reaction between hydrogen and nitrogen to make ammonia (NH₃)?
2. How many molecules of ammonia can be created when four molecules of nitrogen are combined with four molecules of hydrogen? Include a drawing of the molecules in your answer.
3. What ratio of nitrogen and hydrogen molecules would result in no left-over reactants? Explain your answer.
4. If 100.0g of nitrogen is reacted with 100.0g of hydrogen, what is the excess reactant? What is the limiting reactant? Show your work.
5. The following balanced equations represent double replacement reactions that each result in the formation of a precipitate. For each reaction, which ratio of reactants would result in the formation of the greatest amount of precipitate? Cu(NO 3 ) 2 (aq)+2NaOH(aq) Cu(OH) 2 (s)+2NaNO 3 (aq) Note: Cg(OH) 2 is a blue precipitate. FeSO 4 (aq)+2NaOH(aq) Fe(OH) 2 (s)+Na 2 SO 4 (aq) Note: Fe(OH) 2 is a dark green precipitate. Fe(NO 3 ) 3 (aq)+3NaOH(aq) Fe(OH) 3 (s)+3NaNO 3 (aq) Note: Fe(OH) 3 is a red-orange precipitate.
