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.

Answer:
8 Valence Electrons
Explanation:
There are 2 atoms of Hydrogen and 1 atom of Sulfur in the compound. Each Hydrogen atom has 1 electron (which is the valence electron).Sulfur has six valence electrons. Therefore, there is a total of eight valence electrons in H2S.why is an atom electrically neutral
Atoms acquire the stability of a noble gas by losing electrons
Answer:Atoms acquire the stable electron structure of a noble gas by losing electrons. An atom of an element in Group 1A has seven valence electrons. Among Group 1A and 2A elements, the group number is equal to the number of valence electrons in an atom of that element.

How many moles of H3PO4 are contained in 150.0 mL of 18.1 M H3PO4?
Answer:
Number of moles = 2.72 mol
Explanation:
Given data:
Number of moles of H₃PO₄ present = ?
Molarity of solution = 18.1 M
Volume of solution = 150.0 mL (150/1000 = 0.15 L)
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
By putting values,
18.1 M = number of moles / 0.15 L
Number of miles = 18.1 M × 0.15 L
Number of moles = 2.72 mol

Why is a map considered a model?
Answer:
Every map is a representation of reality, thus a model in the broadest sense. Sometimes mapping is distinguished from modelling by stating that mapping is a simple representation of reality, while modelling is trying to cover more complexity in reality.

if you started with 2.34 grams of methane and 8.32 grams of oxeygyn and the combustion reaction went to completion how many grams of CO2 would be produced
Answer:
Mass of CO₂ produced = 5.72 g
Explanation:
Given data:
Mass of methane = 2.34 g
Mass of oxygen = 8.32 g
Mass of CO₂ produced = ?
Solution:
Chemical equation:
CH₄ + 2O₂ → CO₂ + 2H₂O
Number of moles of methane:
Number of moles = mass/molar mass
Number of moles = 2.34 g/ 16 g/mol
Number of moles = 0.146 mol
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 8.32 g/ 32 g/mol
Number of moles = 0.26 mol
Now we will compare the moles of carbon dioxide with oxygen and methane.
CH₄ : CO₂
1 : 1
0.146 : 0.146
O₂ : CO₂
2 : 1
0.26 : 1/2×0.26 = 0.13 mol
Less number of moles of CO₂ are produced by oxygen thus oxygen will react as limiting reactant.
Mass of CO₂:
Mass = number of moles × molar mass
Mass = 0.13 mol × 44 g/mol
Mass = 5.72 g

Explanation:
Since the sun is tilted on it's axis, then the rays of the sun fall on the equator, directly, and that causes it to heat the equator more than the other regions.
Sometimes the sun's rays are on two tropics, Cancer and Capricorn, and that causes the Earth to heat unevenly, which causes wind and ocean currents to form.

Covalent bond is a type of chemical bond which is due to the sharing an electron from each and every atom that is participating in the bond.
Ionic Bond:Ionic bond is a type of bond which is formed due to the complete donation of an electron from one atom to another.
Ionic bond is formed between metals and non-metals. The group which provide the Metal are IA and IIA i.e. S block elements. The group which mostly provide non-metal is VII A i.e. halogens. The Metals give up their ONLY Valance shell electron which is accepted by the Non-metal. This results in formation of ions, The Metals gets the positive charge thus called cation and The non-metal gets a negative charge thus called anion. These Positive and Negative ion attract each other resulting in the formation of IONIC BOND.
_____________________________________The Ionic bond is formed between The metal and non metal because, the metals have low ionization energy due to which the valence shell is ejected out easily, and The Non-Metals have high electron affinity which means that they attract an electron with greater force because they need one electron to complete their octet. As the non metal has high electron affinity and metal have low electron affinity thus the electronegativity difference between the non metal and metal is more than 2 thus they make ionic bond.
_____________________________________Rule of Electronegativity:Electronegativity is the tendency of an atom to attract shared pair of electron. If there is electronegativity difference between the two atom more than 2 then it makes IONIC BOND. If the electronegativity difference is less than 2, it makes COVALENT BOND.
_____________________________________Question:The question says, the KCl has ionic bond but HCl has covalent bond, why?
Answer:Answer is that KCl has electronegativity difference between K and Cl atom more than 2 thus it forms ionic bond. H and Cl has electronegativity difference of less than 2 thus it makes Covalent Bond. K donates its valence electron completely to the Chlorine atom because chlorine has much more electronegativity than potassium(K). H shares an electron with chlorine, it is not completely donated. H has pair of electron for sometime and chlorine has pair of electron for sometime, It is because the Chlorine and Hydrogen has less difference of electronegativity so they attract with almost same electronegativity.
_____________________________________Best Regards,'Borz'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
Titanium metal is used as a structural material in many high-tech applications such as jet engines. What is the specific heat of titanium in J/g°C if it takes 99.7 J to raise the temperature of a 34.7 g block by 5.20°C?
Answer:
0.553 J/g°C
Explanation:
From the question given above, the following data were obtained:
Heat (Q) required = 99.7 J
Mass (M) = 34.7 g
Temperature change (ΔT) = 5.20 °C
Specific heat capacity (C) =?
Thus, we can obtain the specific heat capacity of titanium as follow:
Q = MCΔT
99.7 = 34.7 × C × 5.20
99.7 = 180.44 × C
Divide both side by 180.44
C = 99.7 / 180.44
C = 0.553 J/g°C
Therefore, the specific heat capacity of titanium is 0.553 J/g°C.
