sure its b but im preatty sur dont spell check me plz
In an equation, 40kJ + 2SO₃ (g) -->2SO₂(g) + O₂(g), if pressure added, the equilibrium shifts to the left side of the reaction because it has fewer moles of gas.
<h3>What is Le Ch atelier's principle?</h3>
Le Ch atelier's principle states that if the pressure is added in a nay reaction, then the equilibrium will be shifted toward the side where there are fewer atoms.
In this case, there are fewer moles on the left side.
Thus, when pressure is added, the equilibrium shift to the left side due to Le Ch atelier's principle.

Answer:
0.670 mol
Explanation:
Step 1: Write the balanced reaction for the decomposition of alumina
2 Al₂O₃ ⇒ 4 Al + 3 O₂
Step 2: Calculate the moles corresponding to 34.2 g of Al₂O₃
The molar mass of Al₂O₃ is 101.96 g/mol.
34.2 g × 1 mol/101.96 g = 0.335 mol
Step 3: Calculate the moles of Al produced from 0.335 moles of Al₂O₃
The molar ratio of Al₂O₃ to Al is 2:4.
0.335 mol Al₂O₃ × (4 mol Al/2 mol Al₂O₃) = 0.670 mol Al
Pneumonia is an infection of the lungs caused by fungi, bacteria, ... These conditions include asthma, cystic fibrosis, diabetes, and heart failure.
Answer: Option (d) is the correct answer.
Explanation:
Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.
So, when thermal energy is added to an object then kinetic energy within its molecules will also increase. As a result, temperature of the object will also increase due to increase in number of collisions between the molecules.
Therefore, we can conclude that the statement energy that is associated with temperature, describes thermal energy.
