A mixture of so2(g) and o2(g), formed by the complete decomposition of so3(g), is collected over water at 34°c at a total pressu
Sedbober [7]
The decomposition of so3 to so2 gas and o2 gas can be described in the balanced chemical equation: 

2so3(g) = 2 so2 (g) + 02(g). 

so assuming a complete reaction, the ratio of so2 gas to total products is 2/3 while that of 02 is 1/3. 

Subtracting water's water vapor pressure, 760-40 mm hG = 720 mm Hg.

then the products partial pressures are

so2 = 2/3 * (720) = 480 mm Hg.
o2 = 720-480 = 240 mm Hg.

Which best describes a compound such as sodium chloride? a) a pure substance that can be separated into different elements by ph
vitfil [10]

Answer:

d) a pure substance that can be separated into different elements by chemical means.

Explanation:

Hello,

Sodium chloride (NaCl) is a chemical compound composed by sodium and chlorine. They are chemically bonded through a ionic bond which means that the sodium transfers just one electron (valence electron) to the chlorine to form the bond. Now, if we want to separate them, we must induce a chemical process because bond breaking implies a chemical change, not physical. Thus, a typical way to separate them (break the bond) is via electrolysis in which an electric driving force induce the aforementioned breakdown.

Best regards.

Which has a higher frequency electron or a neutron why ?
8_murik_8 [283]
The electron has a higher frequency compared to the neutron. It can be explained by the way an electron orbits the nucleus of an atom. 

According to Quantum Mechanics, electrons do not really orbit the nucleus of an atom. In fact, the most tightly bound state, the 1s orbital, has no angular momentum at all. This would be the state with the most "kinetic energy" and yet there is no "orbital" motion at all in this state.  

<span>However, there are frequencies associated with each orbital.</span>
