The balanced chemical reaction that would occur here would be:
7O2 + 2 Cl2 --> 2 Cl2O7
To determine the moles of oxygen that is needed in the system, we use the given amount of the product that is needed to be produced. Then, we use the relation from the balanced reaction to relate the product and one of the reactants. We do as follows:
moles Cl2O7 = 60.7 mol
moles O2 = 60.7 mol Cl2O7 ( 7 mol O2 / 2 mol Cl2O7 )
moles O2 = 212.45 mol O2
Therefore, about 213 moles of oxygen gas is needed in order to producr 60.7 moles of dichlorine heptoxide.
Answer: A sulfur ion has more electron shells than a chlorine ion.
Answer:
Option C = 30 j
Explanation:
Given data:
mass of snowboard = 5 Kg
Initial speed = 2 m/s
final speed = 4 m/s
work done = ΔE= ?
ΔE= change in kinetic energy
Solution:
Formula:
K.E (initial) = 1/2 × mv²
K.E (initial) = 1/2 × 5 Kg . (2m/s)²
K.E (initial) = 1/2 × 20 Kg.m²/s²
K.E (initial) = 10 Kg.m²/s² or 10 J
Kg.m²/s² = J
K.E (finial) = 1/2 × mv²
K.E (finial) = 1/2 × 5 Kg . (4m/s)²
K.E (finial) = 1/2 × 5 Kg . 16 m²/s²
K.E (finial) = 1/2 × 80 Kg.m²/s²
K.E (finial) = 40 Kg.m²/s² or 40 J
work done = ΔE = K.E (finial) - K.E (initial)
work done = ΔE = 40 J - 10 J
work done = ΔE = 30 J
Answer: The intermolecular forces increase with increasing polarization of bonds. Boiling point increases with molecular weight, and with surface area. The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds. Intermolecular forces are much weaker than the intramolecular forces of attraction but are important because they determine the physical properties of molecules like their boiling point, melting point, density, and enthalpies of fusion and vaporization.In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces. Ionic bonding is stronger than any of the given intermolecular forces, but is itself NOT an intermolecular force.
Hope this helps.. Stay safe and have a Merry Christmas!!!!!!!!!! :D
Answer:) is related to the change in free energy of the reaction--d
Explanation:
For any reaction that is taking place at any moment the change in Gibbs Free Energy is related to the reaction quotient as
ΔG=ΔG⁰+RTlnQ
where R-Universal Gas Constant, T- Temperature in Kelvin, Q is the reaction quotient
Now when the system is in equilibrum, ΔG⁰ which is the standard Gibb's Free Energy,is then defined as
ΔG⁰=−RTlnK ,
where K is the equilibrium constant. because ΔG becomes 0 and reaction quotient Q = K
The equilibrum constant is related to the change in free energy of the reaction.
because when ΔG is negative, the value of K is high which leads to a spontaneous. reaction
when ΔG is positive, the value of K is low, which leads to a spontaneous. reaction in the opposite direction.
