Answer:
The concentration of SO₂ will decreases
Explanation:
As you can see in the reaction
2 moles of gas ⇆ 3 moles of gas
Based on Le Châtelier's principle, a change doing in a system will produce that the system reacts in order to counteract the change made.
If the pressure is increased, the system will shift to the left in order to produce less moles of gas and decrease, thus, the pressure.
As the system shift to the left, the concentration of SO₂ will decreases
Answer:
D
Explanation:
A reaction becomes spontaneous when the value of the change in free energy is negative.
The relationship between the enthalpy, the entropy and the free energy in a chemical reaction is given below:
G = H – TS
Now, let’s input the values that we have.
One important thing to note is that we have to convert the KJ to Joules and this mean we have to multiply by a conversion factor of 1000. This mean 33KJ is 33,000J
33,000 = 92,200 - 198.7T
33,000 - 92,200 = -198.7T
-59,200 = - 198.7T
T = 59,200/198.7
T = 298k
How many protons, neutrons, and electrons are there in an atom of uranium-238? Write the symbol for this isotope. The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons.
1 moles of any molecules has 6.022 x 10^23 molecules in it
