The volume of Carbon dioxide : 29.12 L
Further explanationGiven
ReactionCH4 (g) + 202(g) → CO2(g) + 2H2O(g)
Oxygen volume = 63.3 L
Methane volume = 29.2 L
RequiredThe volume of Carbon dioxide
Solution
1 mol gas at STP = 22.4 L
mol methane :
[tex]\tt \dfrac{29.2}{22.4}=1.3[/tex]
mol oxygen :
[tex]\tt \dfrac{63.3}{22.4}=2.83[/tex]
limiting reactant : CH₄(smaller ratio:mol/reaction coefficient)
So mol CO₂ based on CH₄
From equation, CO₂ : CH₄ = 1 : 1, so mol CO₂ = 1.3
The volume =
[tex]\tt 1.3\times 22.4=29.12~L[/tex]
The volume of carbon dioxide is produced in the reaction is 29.12 L
The calculation is as follows:We know that
1 mol gas at STP = 22.4 L
So,
The mol methane is
[tex]= 29.2 \div 22.4\\\\= 1.3[/tex]
Now
The mol oxygen is
[tex]= 63.3 \div 22.4\\\\= 2.83[/tex]
Now the volume is
[tex]= 22.4 \times 1.3[/tex]
= 29.12 L

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.

The glancing angle (θ) of a Bragg reflection (n = 1) from a set of crystal planes separated by 99.3 pm is 10.42°. Calculate the wavelength of the X-rays that is used.
Answer:
wavelength λ = 35.92 pm
Explanation:
Given that:
The glancing angle (θ) = 10.42°
Bragg reflection n = 1
wavelength λ = ???
diameter d = 99.3 pm
Using the formula:
nλ = 2dsinθ
we have:
1 × λ = 2 × ( 99.3) × sin (10.42°)
λ = 198.6 × 0.18086
λ = 35.92 pm
The wavelength of the X-rays that is used is equal to 35.9 nanometers.
Given the following data:
Bragg reflection, n = 1Glancing angle (θ) = 10.42°.Distance between planes = 99.3 picometers.To calculate the wavelength of the X-rays that is used, we would apply Bragg's law of reflection:
Mathematically, Bragg's law of reflection is given by the formula:
[tex]n\lambda = 2dsin\theta[/tex]
Where:
n is Bragg reflection.d is the distance between crystal planes.[tex]\lambda[/tex] is the wavelength.[tex]\theta[/tex] is the reflection angle.Substituting the given parameters into the formula, we have;
[tex]1 \times \lambda = 2 \times 99.3 \times 10^{-11} \times sin(10.42)\\\\ \lambda = 1.99 \times 10^{-9} \times 0.1809\\\\\lambda = 3.59 \times 10^{-10}[/tex]
Wavelength = 35.9 nanometers.

seconds. What can you conclude about the rates of these reactions?
A. The rates of reactions A and B are equal.
B. The rate of reaction A is lower.
C. The rate of reaction B is lower.
Answer:
c
Explanation:
because the left side of reactant is take more time to make a product than the first
The rate of these reactions should be considered as the option b. The rate of reaction A is lower.
Conclusion of the rate of reactions:Since Reaction A is completed in 12 seconds, and reaction B is completed in 21 seconds.
So based on this, we can say that the rate of reaction A should be lower as it contain 12 seconds as compared to reaction b.
hence, the option b is correct.
