Consider the chemical equation.

2nbr3 + 3naoh --> n2 + 3nabr + 3hobr

if there are 40 mol of nbr3 and 48 mol of naoh, what is the excess reactant?

n2
nbr3
naoh
hobr

When you perform this reaction, what could remain at the end of the reaction? check all that apply. excess reactant aqueous copper chloride excess reactant aluminum oxygen product solid copper carbon dioxide product aqueous aluminum chloride water
