How many grams of water will be produced when 14.9 L of H2 reacts according to the following equation? H2 + O2 H2O

2moles of H2 will react with 1mole of O2 to form 1 mole of water

If H2 is 14.9

O2 will be 14.9×2=29.8

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
