Answer:
Kc = 1.35x10^7
Explanation:
Let's write the reaction again:
2R + A <------> 2Z Kp = 5.51x10^5
In order to know the value of Kc, we need to write the expression that relations the Kp with Kc which is:
Kp = Kc * (RT)^Δn (1)
Where:
R: 0.082 L atm/ K mol
Δn: difference between the coefficients of the reaction
Kc: equilibrium constant
T: temperature in K
Now, from the equation (1) we can solve for Kc:
Kc = Kp / (RT)^Δn (2)
Now, before do any calculations, let's do first the value of Δn:
Δn = 2 - (2+1) = -1
Now, replacing all values in (2):
Kc = 5.51x10^5 / (0.082*298)^-1
Kc = 1.346x10^7
The third option is the correct one.
The solid product from reaction of sulfuric acid with sucrose is?
- Concentrated <u>sulfuric acid</u> is added to sucrose forming carbon, steam and <u>sulfur</u> dioxide.

<h3>RELATED TO THE QUESTION </h3>
- <u>Solid is one of the four fundamental states of matter</u>. The molecules in a solid are closely packed together and contain the least amount of kinetic energy.
- <u>A solid is characterized by structural rigidity and resistance to a force applied to the surface</u>.
- <u>Sulfuric acid or sulphuric acid, also known as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen</u>, with molecular formula H₂SO₄. It is a colorless, odorless and viscous liquid that is miscible with water at all concentrations.
- <u>Sucrose is common sugar. It is a disaccharide</u>, a molecule composed of two monosaccharides: glucose and fructose. Sucrose is produced naturally in plants, from which table sugar is refined. It has the molecular formula C₁₂H₂₂O₁₁.

The answer is C because the particles in a solid are so tightly packed that there are no spaces in between them and they cannot move around.
It's a single- replacement reaction so Mg+ 2HCl ➡️ H2+ MgCl2
