Please help with Chem I DON'T HAVE ENOUGH TIME! if a 119g sample of water was allowed to evaporate completely, what volume of water vapour would be produced in milliliters?​

As 1 L = 1000 g

so 119 grams = 0.119000 L

Hope it is helpful to u

If yes then plz mark me brainlest

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
