One of the challenges astronauts face is in space travel is the build-up of carbon dioxide in their spacecraft. The average human exhales about 42.0 g of carbon dioxide per hour. One method to remove the excess carbon dioxide from the air is using solid lithium hydroxide: CO2(g) + 2 LiOH(s) → Li2CO3(2) + H2O(l) If a typical canister of LiOH contains 750.0 g, how many hours will it last for one person before it has to be replaced?

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

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
