Water vapour is made up of H2O molecules, where the hydrogen and oxygen atoms have covalent bonds that join them. A jar of hydrogen and oxygen just has oxygen molecules and hydrogen molecules, which are separate.
When we say STP that means the system is at its standard temperature and pressure. Both systems is having the same condition hence temperature and pressure is constant. We then set the amount of gas in both cases to be equal. Hence from the ideal gas law,
PV=nRT we can say that with everything constant, volume must also be constant.
The answer is (2) 2 L of methane gas.
Answer:
trees collect energy from sitting in the sun, the interact with their enviorment because they provide oxygen, and they reproduce when their fruit flowers or leaves fall off.
Explanation:
Clouds are formed by water then it evaporates into air
c.Both the breaking of nuclear bonds and the forming of nuclear bonds.
Explanation:
Nuclear energy is released by the breaking and forming of nuclear bonds. The breaking of nuclear bonds by unstable atoms is known as nuclear fission. The forming of nuclear bonds by combination of light atoms is known as nuclear fusion.
- Nuclear fission is a radioactive decay process in which a heavy nucleus spontaneously disintegrates into lighter ones with the release of energy.
- In nuclear fusion, atomic nuclei combines into larger ones with the release of large amount of energy.
