D. Reducing the pressure

Reaction
2H₂ + O₂ ⇒ 2H₂0 + energy

Two changes would make this reaction reactant-favored
Solution
The formation of H₂O is an exothermic reaction (releases heat)
If the system temperature is raised, then the equilibrium reaction will reduce the temperature by shifting the reaction in the direction that requires heat (endotherms). Conversely, if the temperature is lowered, then the equilibrium shifts to a reaction that releases heat (exothermic)
While on the change in pressure, then the addition of pressure, the reaction will shift towards a smaller reaction coefficient
in the above reaction: the number of coefficients on the left is 3 (2 + 1) while the right is 2
As the temperature rises, the equilibrium will shift towards the endothermic reaction, so the reaction shifts to the left towards H₂ + O₂( reactant-favored)
And reducing the pressure, then the reaction shifts to the left H₂ + O₂( reactant-favored)⇒the number of coefficients is greater
Answer: C. Increasing the temperature
D. Reducing the pressure

Question 4
Calculate the nlass of 7.1 x 1024 formula units of magnesium hydroxide, Mg(OH),.
its me again this is how you find the answer. note: i dont have the periodic table to see the exact atomic mass to find the molar mass however this is the answer:
so the actual formula is Mg(OH) with a 2 as a subscript because there are 2 Mg. so with Mg(OH)2 the Molar mass is 58.32g/mol. 58.32 g/mol x 7.1x1024 = 4.1x1026g

5.Are pure solids included in equilibrium expressions? Explain your answer.
Answer:
Pure solids or liquids are excluded from the equilibrium expression because their effective concentrations stay constant throughout the reaction. The concentration of a pure liquid or solid equals its density divided by its molar mass.

Determine the change in energy when an electron transitions from n= to n=5?
Answer:
ΔE = 13.056 ev
Explanation:
Energy associated with nth state is,
En = -13.6/n²
For n = 1
E₁ = -13.6 / 1²
E₁ = -13.6/1
E₁ = -13.6 ev
Kinetic energy of electron = -E₁ = 13.6 ev
For n = 5
E₅ = -13.6 / 5²
E₅ = -13.6/25
E₅ = -0.544 ev
Kinetic energy of electron = -E₅ = 0.544 ev
Wavelength of radiation emitted:
ΔE = hc/λ = E₅ - E₁
by putting values,
ΔE = -0.544ev - (-13.6 ev )
ΔE = 13.056 ev
Our digestive enzymes are able to break the alpha linkage in potatoes but not the ?? Linkage in paper
Answer:Beta
Explanation:
I watched the video and I got it wrong, the right answer was beta. I can’t explain why because I’ve already forgotten lol
Digestive tract have digestive enzymes which are not able to break beta linkages as humans do not have enzymes which breakdown beta linkages.
What is digestive tract?
It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.
The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.
