In PV = nRT, n is the number of moles. When 8 grams of oxygen are present,
n = 8/32 = 1/4
So PV = RT/4
<u>Answer:</u> The value of for the reaction is
<u>Explanation:</u>

Initial moles of
Volume of the container = 1.00 L
Molarity of the solution =
The given chemical equation follows:
Initial: 0.0150 0.0150
At eqllm: 0.0150-4x 0.0150-3x 2x 6x
The expression of for above equation follows:

Answer:
~69.744 moles of Ca
Explanation:
Using Avogadro's constant , we know that:
1 mole = 6.022 x 10^23 atoms
S0, the number of moles in 4.20 x 10^25 atoms of Ca:
=(4.20 x 10^25 x 1 )/(6.022 x 10^23)
~69.744 moles of Ca
Q2:How many atoms are in 0.35 moles of oxygen?
1 mole = 6.022 x 10^23 atoms
S0, the number of atoms in 0.35 moles of oxygen:
=[0.35 x (6.022 x 10^23)]
=2.1077 x 10^23 atoms of Oxygen

A negative G indicates that there is more free energy in the reactants, or beginning state than in the products, or final state.
Exergonic reactions, which can take place without the supply of energy, are also known as spontaneous reactions.
Not all Gibbs's free energy is bad. Gibbs's free energy is negative for spontaneous reactions at a given temperature and positive for non-spontaneous reactions.
A spontaneous reaction is one that happens under specific circumstances without the addition of energy or outside influence. Since spontaneous reactions can happen rapidly or over the course of several days, months, or years, reaction spontaneity is independent of reaction rate.
