10 moles of hydrogen are allowded to react with 6 moles of oxygen .How much water molecules are obtained?

Since 2H₂ + O₂ ---> 2H₂O

We need 2 moles of hydrogen for each mole of oxygen

So, we need 2(6) = 12 moles of H₂ but since we only have 10 moles,

H₂ is the limiting reagent

So since 2 moles of H₂ gives 2 moles of water,

10 moles of H₂ will give rise to 10 moles of Water with 1 mole of remaining oxygen

kuchisake

kuchisake-onna (口裂け女, "slit mouth woman ") is a malevolent figure appearing in japanese ghost stories, possibly dating back to the edo period. she takes the form of a masked woman who approaches people and asks them if they believe she is pretty.

explanation:

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
