Answer: 10.99

Explanation: because you take the Cao 13.9 and take CO2 which is 10.99 and it makes 24.8 . Which is CaCO3.

Ions that are made of more than one atom are examples of
anastassius [24]
These ions are polyatomic ions. The prefix "poly-" means "many," and the rest of the word "atomic" clearly refers to the atoms themselves. So, if there are two or more atoms in an ion, this ion is polyatomic.

After precipitation falls, the water moves into the lithosphere through
Pie

After precipitation falls, the water moves into the lithosphere through openings in the rock or soil. This process is called percolation.

Therefore, Option C is the correct option.

<h3>What is Evaporation? </h3>

Evaporation is defined as the process of conversion of liquid into vapours.

For example: Conversation of water into water vapours.

But int he question, there is no conversion. So this option is incorrect option.

<h3>What is Sublimation?</h3>

Sublimation is the process of conversion of solid directly into the vapour phase

Since, there is no conversion of of solid into vapours. So, this option also incorrect option.

<h3>What is Mineralization? </h3>

Mineralization is defined as the process through which chemicals which is present in organic matter are decomposed or oxidized easily in the available forms to plants.

As there is no decomposition of minerals. So, this is also incorrect option.

<h3>What is Percolation? </h3>

Percolation is defined as the process in which liquid slowly allow to pass through a filter.

So, this is correct option.

Thus, we concluded that the water moves into the lithosphere through openings in the rock or soil. This process is called percolation.

A mixture of hydrogen and nitrogen gases is placed in a 1.0 L reaction vessel and the reaction is allowed to reach equilibrium a
e-lub [12.9K]

Answer:

a. 0.27 = Kc

b. 8.19×10⁻⁵ = Kp

Explanation:

The reaction is this: 3H₂(g) + N₂ (g)  ⇄ 2NH₃ (g)

As we have the moles of each in the equilibrium and the volume is 1L, we assume the concentrations as molarity.

1.6981 mol/L → H₂

0.5660 mol/L → N₂

0.8679 mol/L → NH₃

Let's make the expression for Kc

Kc = [NH₃]² / [N₂] . [H₂]³

Kc = 0.8679² / 0.5660 . 1.6981³

Kc = 0.27

Let's calculate Kp, derivated from Kc

Kp = Kc . (RT)^Δn where:

Δn is the difference between final moles - initial moles. It is governed by stoichiometry. For this case 2 - (1+3) = -2

Δn it is always for gases

R is the Ideal gases constant

T is Absolute T°

Let's replace data → 0.27 . (0.082 . 700K)⁻² = Kp

8.19×10⁻⁵ = Kp
