2<span> NH3 the ratio between N2 and H2 is </span>1<span> : 3 ... actual moles H2 = 5000 g / </span>2<span> g/mol=2500 so H2 is the limiting reactant</span>
The reaction equation is:
Zn + Pb(NO₃)₂ → Pb + Zn(NO₃)₂
The moles of lead are calculated using:
moles = concentration x volume
moles = 0.25 x 0.15
moles = 0.0375
The moles of zinc are: 1 / 65 = 0.015
We see from the equation that equimolar quantities of zinc and lead should be present. Therefore, lead is in excess and zinc is the limiting reactant.
I think it might mean like energy went off not sure tho
