The change which shift the equilibrium to produce the maximum possible amount of SO₃ is decreasing the temperature.
What is equilibrium principle?According to this principle if any external stress is applied in the equilibrium state then equilibrium will shift towards that side where the external stress will decreases.
In the given chemical equation energy is releases in the form of heat, then in this condition:
Increase in temp will shift the reaction towards the reactant side.Decreasing the pressure will also lead to the decrease in the temperature and in this condition reaction will shift towards product side and will increases the amount of SO₃.Removing the oxygen and SO₃ will not help in increasing the amount of SO₃.Hence decreasing the temperature will produce maximum SO₃.

Is it possible for a reaction with + ΔG° to still be spontaneous in the forward direction? Explain.
Answer:
See explanation.
Explanation:
Hello!
In this case, according to the thermodynamic definition of the Gibbs free energy:
[tex]\Delta G=\Delta H-T\Delta S[/tex]
In the scenario by which G>0 (nonspontaneous) it would be possible for reaction to have a G<0 (spontaneous) if:
- If H>0 and S>0, then the temperature should be increased until the process was entropy-driven for it to be possible.
- If H> and S<0, then it'd be impossible to have an spontaneous process.
- If H<0 and S>0 then the process was not spontaneous.
- If H<0 and S<0 it is possible if the temperature is not high enough to ensure the process is enthalpy-driven.

a. Can A will make a louder and stronger fizz than can B.
b. Can B will make a louder and stronger fizz than can A.
c. The fizz will be the same for both cans.
d. There is not enough information to predict which can will make the louder fizz.
Answer:
The correct answer is -
1. a) The bubbles will shrink, some may vanish.
2. a) Can A will make a louder and stronger fizz than can B.
Explanation:
In the first question, it is given that the bottle is not opened and therefore, squeezing the bottle filled with a carbonated drink will increase the pressure on the carbonated liquid which forces the bubbles to dissolve or displace or vanish as it moves to empty space.
Thus, the correct answer would be - The bubbles will shrink, some may vanish
In the second question, there are two different conditions for two different unopened cans of carbonated water that are different temperatures one at the garage with higher temperature and one in the fridge at low temperature. As it is known that higher the temperature less will be solubility of gas in liquid so gas in can A will be less soluble which means it has more gas and it will make louder and stronger fizz than B which was stored at low temperature.
thus, the correct answer would be - Can A will make a louder and stronger fizz than can B.

Warmer air and colder air can hold the same amount of water vapor.
Warmer air can move faster than colder air.
Warmer air can hold more water vapor than colder air.
Answer:
I got you! I think the answer is D. Warmer air can hold more water vapor than colder air.
Explanation:
Although this statement is true, I could be incorrect, but it is unlikely. When warm air recieves more water vapor it expands while cold air becomes packed and unstable.

A sealed 1.0L flask is filled with 0.500 mols of I_2 and 0.500 mols of Br_2. When the container achieves equilibrium the equilibrium constant is 1.10x10^{-2}. What is the equilibrium concentration of the product, IBr?
Answer:
[IBr] = 0.049 M.
Explanation:
Hello there!
In this case, according to the balanced chemical reaction:
[tex]I_2+Br_2\rightarrow 2IBr[/tex]
It is possible to set up the following equilibrium expression:
[tex]K=\frac{[IBr]^2}{[I_2][Br_2]} =0.0110[/tex]
Whereas the the initial concentrations of both iodine and bromine are 0.50 M; and in terms of [tex]x[/tex] (reaction extent) would be:
[tex]0.0110=\frac{(2x)^2}{(0.50-x)^2}[/tex]
Which can be solved for [tex]x[/tex] to obtain two possible results:
[tex]x_1=-0.0277M\\\\x_2=0.0245M[/tex]
Whereas the correct result is 0.0245 M since negative results does not make any sense. Thus, the concentration of the product turns out:
[tex][IBr]=2x=2*0.0249M=0.049M[/tex]

Hydrogen peroxide with a concentration of 3.0 percent (3.0 g of H2O2 in 100 mL of solution) is sold in drugstores for use as an antiseptic. For a 10.0-mL 3.0 percent H2O2 solution, calculate (a) the oxygen gas produced (in liters) at STP when the compound undergoes complete decomposition and (b) the ratio of the volume of O2 collected to the initial volume of the H2O2 solution.
Answer:
a) 0.099 L
b) 9.9
Explanation:
Now, given the equation for the decomposition of H2O2;
2H2O2(l) ------> 2H2O(l) + O2(g)
Mass of H2O2;
percent w/v concentration = mass/volume * 100
volume = 10.0-mL
percent w/v concentration = 3.0 percent
mass of H2O2 = x
3 = x/ 10 * 100
30 = 100x
x = 30/100
x = 0.3 g of H2O2
Number of moles in 0.3 g of H2O2 = mass/ molar mass
Molar mass of H2O2 = 34.0147 g/mol
Number of moles in 0.3 g of H2O2 = 0.3g/34.0147 g/mol
= 0.0088 moles
From the reaction equation;
2 moles of H2O2 yields 1 mole of oxygen
0.0088 moles of H2O2 = 0.0088 * 1/2 = 0.0044 moles of oxygen
If 1 mole of oxygen occupies 22.4 L
0.0044 moles of oxygen occupies 0.0044 * 22.4/1
= 0.099 L
b) initial volume of the H2O2 solution = 10 * 10-3 L
Hence, ratio of the volume of O2 collected to the initial volume of the H2O2 solution = 0.099 L/10 * 10-3 L = 9.9

A strong beam of light is directed toward a tank filled with water. What caused the beam of light to change direction?
When light travels from less dense air to denser glass or water, it slows down. Slowing down of a ray of light changes the direction of the ray of light.
What is Ray of light?Light that travels in a straight line in one direction is called a ray of light. When a group of light emanates from a source, it is called a beam of light. A beam of light is defined as the path of a photon or a group of photons traveling through a space appearing as a column of light.
There are three types of light rays. They are
Incident raysReflected raysRefracted raysExample of a beam is a beam of light with a pass from a laser or laser pointer. A beam of light is made up of particles called photons that carry specific amounts of energy. We cannot measure the length of a beam.
Thus, when light travels from less dense air to denser glass or water, it slows down. Slowing down of a ray of light changes the direction of the ray of light.
