Answer: 75.7 % yield
Explanation:
The balanced chemical equation is:
According to stoichiometry :
68.2 g of will require = 64 g of
Thus 7.5 g of will require = of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 68.2 g of give = 96 g of
Thus 7.5 g of give = of
% yield=
Thus 75.7 % yield is there.
Answer:
Explanation:
From the given information:
The density of O₂ gas =
here:
P = pressure of the O₂ gas = 310 bar
=
= 305.97 atm
The temperature T = 415 K
The rate R = 0.0821 L.atm/mol.K
molar mass of O₂ gas = 32 g/mol
∴
= 287.37 g/L
To find the density using the Van der Waal equation
Recall that:
the Van der Waal constant for O₂ is:
a = 1.382 bar. L²/mol² &
b = 0.0319 L/mol
The initial step is to determine the volume = Vm
The Van der Waal equation can be represented as:
where;
R = gas constant (in bar) = 8.314 × 10⁻² L.bar/ K.mol
Replacing our values into the above equation, we have:
After solving;
V = 0.1152 L
∴
= 277.77 g/L
We say that the repulsive part of the interaction potential dominates because the results showcase that the density of the Van der Waals is lesser than the density of ideal gas.
The attractive forces between the neighboring particles of a substance are known as intermolecular forces. The state of a substance relies upon the strength of the intermolecular forces among the molecules in a substance.
There are three kinds of intermolecular forces, that is, the dipole-dipole forces, ion-dipole forces, and the London dispersion forces. On the basis of the kinds of intermolecular forces, it is concluded that the intermolecular forces primarily relies upon the nature of the molecule's bonding.
Thus, on the basis of the nature of bonding between the associating atoms in a molecule one can know about the nature of intermolecular forces. On the basis of Newton's law of gravitation, all the physical bodies get fascinated towards each other, and it is known that each physical body comprises of matter. Thus, the matter is fundamentally attracted by other matter.
Answer:
118 elements
Explanation:
Of these 118 elements, 94 occur naturally on Earth.
The catalyst would increase the rate of the forward reaction...
And increase the rate of the backward to the same extent thus not affecting equilibrium.
