The gas has already created enough pressure to become a gas, which is the most expandable it could turn in to. Thats what i think, hope it helps.

How to find molar mass
Shkiper50 [21]

Answer:

Multiply the element's atomic mass by the number of atoms of that element in the compound. This will give you the relative amount that each element contributes to the compound. For hydrogen chloride, HCl, the molar mass of each element is 1.007 grams per mole for hydrogen and 35.453 grams per mole for chlorine.

When determining an element’s chemical properties, the most important subatomic particle to look at is
Crank

Answer:

Electrons

Explanation:

When determining the chemical properties of elements, the most important subatomic particle to consider is the electrons.

Electrons are negatively charged particles that orbits an atom. They occupy the extranuclear space of an atom.

These electrons determines the chemical properties of each atom. Most especially, the valence ones. All elements wants to resemble the noble gases, so they alter their number of electrons in order to attain this stable state.

2. How does the way elements are grouped in the periodic table serve as an advantage to scientists?
Goryan [66]
When looking down the groups the elements have an equal number of electrons in the outer shell. This means they react in a similar way making it easier for scientists to use.

The equilibrium constant, Kc, is calculated using molar concentrations. For gaseous reactions another form of the equilibrium co
Anarel [89]

Answer:

Kp = 1.41 x 10⁻⁶

Explanation:

We have the chemical equation:

2 A(g) + 3 B(g)⇌ C(g)

In which A and B are the reactants and C is the product. We calculate first the change in the number of moles of gas (Δn or dn):

dn= (sum moles products - sum moles reactants)

   = (moles C - (moles A + moles B))

   = (1 - (2+3))

   = 1 - 5

   = -4

We have also the following data:

Kc = 63.2

T= 81∘C + 273 = 354 K

R = 0.082 L.atm/K.mol (it is a constant)

Thus, we introduce the data in the mathematical expression for the relation between Kp and Kc:

Kc = (RT)^{dn}= (0.082 L.atm/K.mol x 354 K)⁻⁴ = 1.41 x 10⁻⁶
