i want food real bad
please bro
N2+3H2 ---> 2NH3 Which reactant limits the reaction, and how many moles of NH3 form?
Limiting reactant.. H2
NH3 formed ;; 2.0 mol
Hydrogen is turned wayy up. You have 2.0 mol N2 and 12.0 mol H2. Which reactant controls the volume, and how many moles of NH3 form?
Limiting Reactant ;; N2
4.0 mol NH3 produced
convert 9.0 x 1023 molecules of O2 into moles
9.0 x 1023 molecules of O2 , so the answer would be 1.5 moles
like food is so good bro im so hungry
feed me seymour
