Below is the solution:
n equation showing conservation of mass of reactants and products:
2H2O --> 2H2 & O2 

what is the mass of the oxygen gas produced, from 178.8 g H2O , (using molar masses: 
178.8 g H2O @ (1mol O2)(@ 32.00 g/mol) / (2molH2O)(18.02g/mol) = 
your answer (4 sigfigs): 158.8 g O2 

178.8 g H2O ---> 20.0 H2 & 158.8 O2

Please 1) describe what is meant by the terms short-wave and long-wave energy, 2) name a specific type of electromagnetic energy

Studentka2010 [4]

Answer:

wavelength difference
ultraviolet, infrared
shortwave = Sun; longwave = Earth

Explanation:

The terms shortwave and longwave radiation refer to the wavelength of the radiation, which is the distance from the crest of one wave to the crest of another. The wavelength reflects the energy of the wave. Longwave radiation is less energetic, while shortwave has more energy. Longwave radiation has even longer wavelengths than red light in the visible spectrum, while ultraviolet radiation has wavelengths shorter even than the shortest violet visible light.
Ultraviolet is not the only kind of shortwave radiation; in fact, it is the shortwave radiation closest to visible light on the electromagnetic spectrum. X rays and gamma rays have far shorter wavelengths and thus are more energetic. Infrared radiation is the type of the longwave radiation that is closest to the visible spectrum. Radiation with much longer wavelengths than infrared light include microwaves and radio waves.
The Sun produces its own radiation since it is a body that is much more massive and with a much higher temperature than the Earth. Because of this, the radiation emitted from the Sun is mostly shortwave radiation. The Earth emits radiation as well, but it is infrared radiation emitted in the form of heat that is not visible to human eyes.

What is a major difference between the Roman Catholic Church and the Eastern Orthodox Church?

Fynjy0 [20]

The catholic church believes the pope to be infallible in matters of doctrine. orthodox believers reject the infallibility of the pope and consider their own patriarchs and thus they subject to error.
