Remarkably, a catalytic system that uses light energy to hydrolyze water into hydrogen h2(g) and o(g) has been devised (science 334, 2011: 645-648) to capture and efficiently store solar energy. hydrogen is "clean burning" in that it yields only h2o. in this problem you will contrast the combustion of 1 kgh2(g) to that of 1 kg of n-octane.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.

you need to have a picture of the atom that way we can answer it

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
