What is the mass number for an atom of xenon containing 54 protons and 75 neutrons?
Answers
Answer:
Answer should 133
Explanation:
all you have to do is add the protons and neutrons
The mass number for an atom of xenon containing 54 protons and 75 neutrons is 129 amu.
What is an Atomic mass of an atom?The Atomic mass of any atom may be defined as the mass of an atom that is togetherly constituted by protons and neurons in the nucleus of an atom. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number).
The mass number of Xenon is calculated by the following formula:
The Number of neutrons = Mass number - Atomic number.
where, number of neutrons = 75, and number of protons = 54.
75 = Mass number - 54 (number of protons = atomic number).
Mass number = 75 + 54 = 129 amu.
Therefore, the mass number for an atom of xenon containing 54 protons and 75 neutrons is 129 amu.

Can a stable compound be made from these two atoms? Explain why or why not.
Answers
The given oxygen and lithium atoms are unable to form a stable compound.
The given atoms to form a stable compound has been oxygen and lithium.
A stable compound has been formed when the transfer of atom has been resulted in the completion of the valence shell of both the electrons.
The oxygen has 6 valence electrons and require to gain 2 electrons to form the stable compound. The Lithium has 3 electrons and has been able to lose 1 electron to form a stable compound.
Since, the formation of stable compound between oxygen and lithium requires transfer of 2 electrons, and there has been availability of 1 electron from Li. Thus, the atoms are unable to form a stable compound.

The relationships among which variable quantities are expressed by the ideal gas law equation?
A. pressure, volume, temperature, number of moles
B. volume, temperature, number of moles, gas constant
C. pressure, volume, number of moles, mass
D. pressure, volume, temperature, molar mass
Answers
Answer:
A. Pressure, volume, temperature, number of moles
The relationships among pressure, volume, temperature, and the number of moles are expressed by the ideal gas law equation. Therefore, option A is the correct answer.
The ideal gas law equation is PV = nRT, where P represents the pressure of the gas, V represents its volume, n represents the number of moles of gas present, T represents its temperature, and R is the ideal gas constant. This equation describes the behavior of an ideal gas at standard temperature and pressure (STP).
By manipulating the ideal gas law equation, we can calculate various properties of gases, including their density, molar mass, and molecular weight. This equation is widely used in chemical engineering, thermodynamics, and other fields that deal with gases.
Thus, option A is correct.

when an electron moves from a higher orbit to a lower one does it always follow the same path explained
Answers
Yes, electron follows the same path when it absorb and loses energy.
Yes, when an electron moves from a higher orbit to a lower orbit it always follow the same path as it moves from a lower orbit to a higher orbit. When electron absorb energy it has the power to move from lower orbit to higher orbit or energy level.
While on the other hand, when an electron loses that energy, it comes back to its original position from which it moves earlier when it absorb energy so we conclude that electron follows the same path when it absorb and loses energy.

Drag electrons back and forth until the molecule of oxygen (O2) is stable. Click Check to confirm your molecule is stable. How many pairs of shared electrons are there in a stable molecule of oxygen?
Answers
Answer:
2 pairs (4 electrons)
Explanation:
In a molecule of oxygen there are 2 oxygen atoms. There are 6 electrons in the outer shells of oxygen atoms. When 2 oxygen atoms form a covalent bond they share their electrons. In a diagram this would be represented by the overlap of the two circles representing the outer shells of both oxygen atoms. If each oxygen atom 'puts forward' 2 electrons into the centre, then 4 will be shared overall for each atom, making both atoms have full outer shells of 8 electrons each. 4 electrons make 2 pairs, hence the answer.

You have 150.0 mL of a 0.415 M solution of Ce(NO₃)₄.
a) What mass (in grams) of Ce(NO₃)₄ would be required to make the solution?
B) What is the concentration of the nitrate ions in the solution ?
C) If the original solution was diluted to 350.0 mL, what would be the new concentration of the Ce(NO₃)₄ in the solution?
Answers
A. The mass (in grams) of Ce(NO₃)₄ that will be required to make the solution is 24.16 g
B. The concentration of the nitrate ions in the solution is 1.66 M
C. The new concentration of the Ce(NO₃)₄ solution is 0.178 M
We'll begin by calculating the number of mole of Ce(NO₃)₄ in the solution.
Molarity = 0.415 M
Volume = 150 mL = 150 /1000 = 0.15 L
Mole of Ce(NO₃)₄ =?Mole = Molarity × Volume
Mole of Ce(NO₃)₄ = 0.415 × 0.15
Mole of Ce(NO₃)₄ = 0.06225 moleA. Determination of the mass of Ce(NO₃)₄ required to make the solution.
Mole of Ce(NO₃)₄ = 0.06225 mole
Molar of Ce(NO₃)₄ = 140.12 + 4[14 + (16×3)]
= 140.12 + 4[14 + 48]
= 140.12 + 4[62]
= 140.12 + 248
= 388.12 g/mol
Mass of Ce(NO₃)₄ =?Mass = mole × molar mass
Mass of Ce(NO₃)₄ = 0.06225 × 388.12
Mass of Ce(NO₃)₄ = 24.16 gTherefore, 24.16 g of Ce(NO₃)₄ is required to make the solution.
B. Determination of the concentration of the nitrate ion, NO₃¯ in the solution.
In solution, Ce(NO₃)₄ will dissociate as follow:
Ce(NO₃)₄ (aq) —> Ce⁴⁺(aq) + 4NO₃¯(aq)
From the balanced equation above,
1 mole of Ce(NO₃)₄ contains 4 moles of NO₃¯
Therefore,
0.415 M solution of Ce(NO₃)₄ will contain = 0.415 × 4 = 1.66 M NO₃¯
Thus, 1.66 M of the nitrate ion, NO₃¯, is present in the solution.
C. Determination of the new concentration of the Ce(NO₃)₄ solution.
Volume of stock solution (V₁) = 150 mL
Molarity of stock solution (M₁) = 0.415 M
Volume of diluted solution (V₂) = 350 mL
Molarity of diluted solution (M₂) =?
M₁V₁ = M₂V₂0.415 × 150 = M₂ × 350
62.25 = M₂ × 350
Divide both side by 350
M₂ = 62.25 / 350
M₂ = 0.178 MTherefore, the new concentration of the Ce(NO₃)₄ solution is 0.178 M

D.

Answers
Explain:
10=1
200=?
200/10=20
The time taken by the car driving at 10m/s to move 200m is 20 seconds. The speed of car is 10m/s. Thus option C is correct.
What is speed?Speed is defined as a measurement of the length of time it takes for an object to travel a certain distance.
The SI unit of speed is m/s, and speed is defined as the ratio of distance to time.
A change in speed is an example of acceleration because it is a change in velocity. Acceleration could be for positive or negative. Deceleration is another name for negative acceleration.
There are four types of speed.
Uniform speedVariable speedAverage speedInstantaneous speedSpeed can be expressed as
Speed = Distance / Time
Given, Distance = 200 m
Time = 10 m/s
Speed = 200m / 10m/s
= 20 seconds
Thus, the time taken by the car driving at 10m/s to move 200m is 20 seconds. The speed of car is 10m/s. Thus option C is correct.
