18.0g of N2 reacts with 3.03 of H2 what is the limiting reactant Molar Masses:
N2= 28g/mol
H2= 2.02g/mol

Apiece of metal with a length of 1.42 cm was measured using four different instruments. which of the following measurements is the most accurate?

For the reaction shown, find the limiting reactant for each of the following initial amounts of reactants. 4al(s)+3o2(g)→2al2o3(s) a) 1 molal, 1 mol o2 b) 4 molal, 2.6 mol o2 c) 16 molal, 13 mol o2 d) 7.4 molal, 6.5 mol o2

Answer explain why it is not possible to deduce a complete order of reactivity.
