a group od atoms bonded together representing the smallest fundemental unit
Explanation:
Answer:
3.0 moles of water
Explanation:
Having the balanced equation of water production
2H2 (g) + O2 (g) -----> 2H2O (g)
Given that 3.0 moles of hydrogen gas reacts with 1.8 moles of oxygen gas
from the 2 moles of hydrogen are required to react with 1 mole of oxygen
1.8 moles of oxygen,requires 1.8 mol O2 x 2 mol H2/ 1 mol O2 = 3.6 mol H2
this means that H2 is the limiting reagent while oxygen is in excess,thus we use the moles of H2 to find the ,moles of water produced.
from the equation, 2 moles of H2 produces 2 moles of H2O
moles of H2O = 3.0 mol H2 x 2 mol H2O/ 2mol H2 = 3.0 molH2O
Therefore 3.0 moles of water are produced.
