Answer:
reee, here is your answer.
Explanation: CH3OH(l) + 3O2(g) rightarrow CO2(g) + 3H2O(g) CH3OH(l) + O2(g) rightarrow CO2(g) + 2H20(g) CH3OH(l) + 2O2(g) rightarrow 2CO2(g) + 4H20(g) 2CH3OH(l) + 3O2(g) rightarrow 2CO2(g) + 4H20(g) Correct Calculate Delta H degree rxn at 25 degree C.
Answer:
4 mol of lithium nitride would be produced
Explanation:
6Li + N2 → 2Li3N
This equation means that 6 mol of lithium are reacted with 1 mol of nitrogen to make, 2 mol of lithium nitride.
So this is the rule of three to find out, how many moles of lithium nitride are been made, from 12 mol of Li.
6 Li _____ 2 Li3N
12 Li ________ (12. 2) / 6 = 4 moles
