What volume of sulfur trioxide would be produced by reaction of 2.56 L of oxygen with excess sulfur at STP?
shepuryov [24]
The balanced chemical reaction would be :

S + O2 = SO2
2SO2 + O2 = 2SO3

We are given the amount of oxygen to be used in the reaction. This will be the starting value in the calculations. We do as follows:

2.56 L O2 ( 1 mol / 22.4 L) ( 1 mol SO2 / 1 mol O2 ) ( 2 mol SO3 / 2 mol SO2 ) 22.4 L / 1 mol =  2.56 mol SO3

1 Select the correct answer! Which statement best explains the octet rule? A. Atoms gain, lose, or share electrons to achieve a
Ostrovityanka [42]

Answer:

A. Atoms gain, lose, or share electrons to achieve a full valence shell

Explanation:

The octet rule is best explained as the process in which atoms lose or gain or share electrons to achieve a full valence shell.

  • In this process bonds are formed when there is an attraction between the two substances.
  • For electrovalent compounds, an atom will lose electrons or gain electron to form an ion, the electrostatic attraction causes the bond formation.
  • Covalent compounds, form by sharing of electrons.

Therefore, the octet rule is attained when atoms gain full valence configuration.
