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.A soccer ball was kicked it had the mass of .42 kg and accelerated at 25m what is the force

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.

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.

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
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.

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

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.

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
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.

A student measures the time it takes for two reactions to be completed.
Reaction A is completed in 12 seconds, and reaction B is completed in 21
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.
