Answer:
They are resonance contributors
Explanation:
Resonance structures are structures that differ only in the distribution or placement of electrons.
Considering the two structures, we can easily see that the two species have the same total number of bonds and electrons differing only in the distribution of these electrons.
Hence, they are resonance contributors.

The moons of Jupiter
orbit Jupiter because
they are pulled toward
Jupiter. The moons of
Jupiter are too far to
be pulled into Earth's
orbit.
Yes or No
Answer:
Yes
Explanation:
Jupiter is a very large planet. Larger planets usually have stronger gravity, which pulls planets toward each other.
The moons of Jupiter are by Jupiter. (I know, that wasn't a smart thing to say because you know that, but, hey, I had to.) With this being the case, Jupiter is also an inside planet.
- Inside Planets
Planets that are closest to the sun and orbits the sun
There are 2 things that are the cause of the moons of Jupiter not being pulled by earth.
1. Jupiter has strong gravity which pulls the moons, and Jupiter is being pulled by the sun's INCREDIBLE gravity.
2. Earth is an outside planet. It is too far away from Jupiter to attract Jupiter's moons.
- Outside Planet
A planet that is away from the sun, but still orbits the sun
Hope this helps! :D

Calculate the number of moles of aluminum, sulfur, and oxygen atoms in 3.00 molesmoles of aluminum sulfate, Al2(SO4)3Al2(SO4)3. Express the number of moles of AlAl, SS, and OO atoms numerically, separated by commas.
Answer:
[tex]n_{Al}=6.00molAl\\\\n_{S}=9.00molS\\\\n_{O}=36.0molO[/tex]
Explanation:
Hello!
In this case, when analyzing the moles of an element inside a compound, we need to keep in mind that a mole ratio should be set up; thus, for aluminum sulfate, we have the following ones:
[tex]\frac{2molAl}{1molAl_2(SO_4)_3} \\\\\frac{3molS}{1molAl_2(SO_4)_3} \\\\\frac{12molO}{1mol1molAl_2(SO_4)_3}[/tex]
Thus, starting by 3.00 moles of aluminum sulfate, the moles of each element turn out:
[tex]n_{Al}=3.00molAl_2(SO_4)_3*\frac{2molAl}{1molAl_2(SO_4)_3} =6.00molAl\\\\n_{S}=3.00molAl_2(SO_4)_3*\frac{3molS}{1molAl_2(SO_4)_3} =9.00molS\\\\n_{O}=3.00molAl_2(SO_4)_3*\frac{12molO}{1molAl_2(SO_4)_3}=36.0molO[/tex]

mole of KOH is dissolved in 10 litres of
water. What will be the pH of the solution?
12
Ans: pH = 11
Answer:
11
Explanation:
Moles of KOH = [tex]10^{-2}[/tex]
Volume of water = 10 liters
Concentration of KOH is given by
[tex][KOH]=\dfrac{10^{-2}}{10}\\\Rightarrow [KOH]=10^{-3}\ \text{M}[/tex]
[tex][KOH][/tex] is strong base so we have the following relation
[tex][KOH]=[OH^{-}]=10^{-3}\ \text{M}[/tex]
[tex]pOH=-\log [OH^{-}]=-\log10^{-3}[/tex]
[tex]\Rightarrow pH=14-3=11[/tex]

hope it helps
Enzyme lactase catalyzes the hydrolysis of the glycosidic bond of lactose to form galactose and glucose.
What is lactase?Lactase can be described as an enzyme produced by many organisms. Lactase is located in the small intestine of humans and other mammals. It is essential to accomplish the digestion of milk and it breaks down lactose that gives milk its sweetness.
A person with a deficiency of lactase, and who consume dairy products, may experience the symptoms of lactose intolerance. Lactase is a part of the β-galactosidase family of enzymes and is a glycoside hydrolase involved in the hydrolysis of lactose into constituent galactose and glucose monomers.
The β-glycosidic bond in D-lactose in metabolism is hydrolyzed to form D-galactose and D-glucose, which can be absorbed into the bloodstream. The optimum temperature of the human lactase is about 37 degrees Celcius and the optimum pH of the human lactase is equal to 6.

Explanation:
Nitrogen can exist as a solid, a liquid, or a gas. Which of the following lists the
phases of nitrogen in order of increasing density?
1. liquid, gas, solid
2. gas, liquid, solid
3. gas, solid, liquid
4. solid, liquid, gas
The phases of nitrogen in order of increasing density is solid, liquid, and gas.
Nitrogen is known to be odorless and colorless. Nitrogen makes up about 78% of the gases that we've in the atmosphere. It has an atomic number of 7 and is represented with the symbol N.It should be noted that nitrogen can be a solid, a liquid or a gas. When nitrogen is at ordinary pressure, it is known to be a gas. In a case whereby nitrogen is below 77°K, then it's a liquid and it's a solid when it's below 63°K.The density explains the mass per unit volume that nitrogen has when it's either at gaseous, solid or liquid state. It should be noted that the highest density is at its gaseous state.Therefore, the phases of nitrogen in order of increasing density will then be solid, liquid, and gas.In conclusion, the correct option is D.

what would be a logical explanation for why carbon dioxide increased over the time shown in the graph.
A. the area of land for crops incresed
b. the amount of plants eaten by animal increased
c. the amount of fossil fuels being burned increased
d. the amount of wood being burned by pepole increased
Answer:
c. the amount of fossil fuels being burned increased
Explanation:
Carbon dioxide gas concentration increased over the time due to burning of fossil fuels increased. Fossil fuels are organic compounds which releases carbondioxide gas as a result of burning of fossil fuels in the engines of vehicles and industries. With the passage of time, number of vehicles increases in the world which needs more fossil fuels and due to burning of that fossil fuels, more carbondioxide gas is released.
A 1.00-L flask was filled with 2.00 moles of gaseous and 2.00 moles of gaseous and heated. After equilibrium was reached, it was found that 1.21 moles of gaseous was present. Assume that the reaction
SO2 + NO2 ⇌ SO3 + NO
occurs under these conditions. Calculate the value of the equilibrium constant, K, for this reaction.
Answer:
2.35
Explanation:
A 1.00-L flask was filled with 2.00 moles of gaseous SO₂ and 2.00 moles of gaseous NO₂ and heated. After equilibrium was reached, it was found that 1.21 moles of gaseous NO was present. Assume that the reaction
SO₂ + NO₂ ⇌ SO₃ + NO
occurs under these conditions. Calculate the value of the equilibrium constant, K, for this reaction.
Step 1: Calculate the molar concentrations
Since the reaction takes place in a 1.00 L flask, the molar concentrations are:
[SO₂]i = 2.00 M
[NO₂]i = 2.00 M
[NO]eq = 1.21 M
Step 2: Make an ICE chart
SO₂ + NO₂ ⇌ SO₃ + NO
I 2.00 2.00 0 0
C -x -x +x +x
E 2.00-x 2.00-x x x
Step 3: Calculate the concentrations at equilibrium
The concentration of NO at equilibrium is 1.21 M. Then, x = 1.21.
[SO₂]eq = 2.00-1.21 = 0.79 M
[NO₂]eq = 2.00-1.21 = 0.79 M
[SO₃]eq = x = 1.21 M
[NO]eq = x = 1.21 M
Step 4: Calculate the value of the equilibrium constant, K, for this reaction
K = [SO₃] × [NO]/[SO₂] × [NO₂]
K = 1.21²/0.79² = 2.35

Element X has two naturally occurring isotopes, 65X (isotopic mass 65.0457 amu, abundance 20.53%) and 67X (isotopic mass 66.9704 amu, abundance 79.47%). Calculate the atomic mass of element X.
Answer:
66.5753 amu
Explanation:
From the question given above, the following data were obtained:
Isotope A (⁶⁵X):
Mass of A = 65.0457 amu
Abundance of A = 20.53%
Isotope B (⁶⁷X):
Mass of B = 66.9704 amu
Abundance of B = 79.47%
Atomic mass of X =?
The atomic mass of X can be obtained as follow:
Atomic mass = [(mass of A × A%)/100] + [(mass of B × B%)/100]
= [(65.0457 × 20.53)/100] + [(66.9704 × 79.47)/100]
= 13.3539 + 53.2214
= 66.5753 amu
Therefore, the atomic mass of X is 66.5753 amu.
Element X, with an atomic mass of 66.58 amu, has 2 naturally occurring isotopes, ⁶⁵X (65.0457 amu, 20.53%) and ⁶⁷X (66.9704 amu, 79.47%).
What is the average atomic mass?The average atomic mass (atomic mass) of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance.
Element X has 2 isotopes:
⁶⁵X with an isotopic mass of 65.0457 amu and an abundance of 20.53% (0.2053).⁶⁷X with an isotopic mass of 66.9704 amu and an abundance of 79.47% (0.7947).We can calculate the average atomic mass of X using the following expression.
mX = m⁶⁵X × ab⁶⁵X + m⁶⁷X × ab⁶⁷X
mX = 65.0457 amu × 0.2053 + 66.9704 amu × 0.7947
mX = 66.58 amu
Element X, with an atomic mass of 66.58 amu, has 2 naturally occurring isotopes, ⁶⁵X (65.0457 amu, 20.53%) and ⁶⁷X (66.9704 amu, 79.47%).

determine the mass of 840 cm3 of oxygen gas, O2 at rtp
Answer:
Mass = 0.96 g
Explanation:
Given data:
Volume of oxygen = 840cm³
Temperature = at room = 25°C
Pressure = at room = 1 atm
Mass of oxygen = ?
Solution:
Volume of oxygen = 840 cm³ × 1 L /1000 cm³ = 0.84 L
Temperature = 25 +273.15k = 298.15 K
Formula:
PV = nRT
n = PV/RT
R = 0.0821 atm.L/mol.K
n = 1 atm × 0.84 L / 0.0821 atm.L/mol.K × 298.15 K
n = 0.84 atm.L / 24.48 atm.L/mol
n = 0.03 mol
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 0.03 mol × 32 g/mol
Mass = 0.96 g
