The average kinetic energy of a mole of gas can be determined through the equation KE= 1.5 nRT where R is the gas constant equal to <span>8.314 J/K-mol and T is temperature, The temperature for this problem is 125 Kelvin and n is equal to 1 mole. KE then is equal to 1558.88 Joules.</span>
The balanced chemical reaction is expressed as:
<span>8SO2 + 16H2S = 3S8 + 16H2O
We are given the initial amount of the reactants. From there, we determine the limiting reactant. We do as follows:
87.0 g SO2 ( 1 mol / 64.07 g ) = 1.36 mol SO2 ( 16 mol H2S / 8 mol SO2 ) = 2.72 mol H2S
87.0 g H2S ( 1 mol / 34.08 g ) = 2.55 mol H2S ( 8 mol SO2 / 16 mol H2S ) = 1.28 mol SO2
Therefore, the limiting reactant would be H2S. We calculate the maximum amount of S8 that can be produced from the amount of H2S.
2.55 mol H2S ( 3 mol S8 / 16 mol H2S ) ( 256.48 g / 1 mol ) = 122.63 g S8</span>
To satisfy the octet rule, there has to be eight electrons in phosphorus's outermost shell. Phosphorus has five electrons in its valence shell, fluorine has seven. This means that phosphorus would have to bond to three fluorine atoms in order to have eight electrons in its valence shell without breaking the octet rule in any one of the fluorine atoms.
Since it has 4 electrons, it needs only 4 more to be stable. Therefore, it would share electrons, which is a covalent bond.
Answer: Covalent bond
Answer: Kinetic Energy is already moving and is not at rest. Potential Energy is purely based on the position of the object and also the condition of the object.
