4g of hydrogen reacts with 20g of oxygen to form water. the mass of water formed is
adiz05:
oxygen is the limiting reagent so 36 g O2 gives 36g water thus 20 g gives 36*20/32
ie,22.5g

hello
__________________________________________________________
come to the reaction
2H₂ + O₂ → 2H₂O
Reactents :
Hydrogen = 2 moles = 2 X 2 = 4 g
Oxygen = 32 g
it means
4 g H reacts with 32 g of oxygen to form 36 g of water
But the second mole needs more oxygen
SO only one molecule formed of 18 g

that is true but the answer is 22.5 g of water 36*20/32
what a nonsense type of ans Thxxx

Answer:
2H2O + O2 ------ > 2H2O i.e 4g + 32g ----- > 36g
32grams of O2 gives 36grams of H2O.
20grams =?
= 36/32 * 20
= 22.5
