This is the balanced chemical equation for the reaction that produces ammonia (NH3) from nitrogen (N2) and hydrogen (H2). N2 (g)+3 H2 (g) - 2 NH3 (g)

A. Using the mole ratio from the chemical equation, calculate how many moles of ammonia (NH3) would be produced if 2.5 moles of nitrogen (N2) reacted with
excess hydrogen (H2). .
