What is the ground-state electron configuration of terbium (Tb)?
Answers
The answer is that the ground-state electron configuration of terbium (Tb) is [Xe] 4f9 6s2.
This means that there are 9 electrons in the 4f orbital and 2 electrons in the 6s orbital of the atom.
Terbium is a rare earth element with the atomic number 65. Start filling the electron orbitals in order of increasing energy levels, following the Aufbau principle. The noble gas that precedes terbium is xenon (Xe), with an atomic number of 54. The electron configuration of xenon is [Xe].
After filling the 54 electrons for xenon, we have 11 electrons left for terbium. The next available orbitals are 4f and 6s. Fill the 4f orbital with 9 electrons, and the 6s orbital with 2 electrons, to complete the electron configuration of terbium.
To determine its electron configuration, we start with the noble gas that precedes it in the periodic table, which is xenon (Xe). The electron configuration of Xe is [Kr] 4d10 5s2 5p6. The brackets represent the noble gas configuration, and the remaining electrons are added to it.
In the case of terbium, the 4f and 6s orbitals are filled before the 5d orbital, which is why the 4f orbital has 9 electrons and the 6s orbital has 2 electrons. This is in accordance with Hund's rule, which states that electrons occupy individual orbitals within a subshell before pairing up.

Answers
To determine the amount of baking soda to add to 100 mL of acetic acid
you can use stoichiometry. The balanced chemical equation for the reaction between baking soda and acetic acid is:
NaHCO3(s) + HC2H3O2(aq) → NaC2H3O2(aq) + CO2(g) + H2O
The mole ratio of baking soda to acetic acid is 1:1. This means that for every mole of baking soda, one mole of acetic acid reacts. Therefore, you need to add one mole of baking soda to 100 mL of acetic acid.2. The molar mass of sodium carbonate (Na2CO3) is 106 g/mol. Using the equation moles = mass (g) /molar mass, the moles of sodium carbonate used can be calculated as follows:moles = 5 g / 106 g/molmoles = 0.04717 mol (rounded to 5 decimal places)3. The balanced chemical equation shows that one mole of baking soda produces one mole of carbon dioxide gas. At standard temperature and pressure (STP), one mole of any gas has a volume of 22.4 L. Therefore, the volume of carbon dioxide gas produced can be calculated as follows:volume of gas = moles of gas x 22.4 L/molvolume of gas = 0.04717 mol x 22.4 L/molvolume of gas = 1.056 L (rounded to 3 decimal places)Therefore, if 5 g of baking soda reacted at STP, 1.056 L of carbon dioxide gas would be produced.

A stock solution of sodium sulfate, Na2SO4 has a concentration of 1.00 M. The volume of this solution is 50 mL. What volume of a 0.25 M solution could be made from the stock solution?
Answers
We can make a 0.25 M solution with a volume of 200 mL from the stock solution.
How do you calculate the volume of a 0.25 M solution that could be made from the stock solution?We can use the dilution formula to fix this issue:
C1V1 = C2V2
where C1 and V1 represent the initial (stock) solution's concentration and volume, and C2 and V2 represent the end (diluted) solution's concentration and volume.
In order to write: "We want to determine the volume of a 0.25 M solution that can be created from the stock solution."
C2 = 0.25 M V2 =? where C1 = 1.00 M and V1 = 50 mL.
Using the dilution formula with these values as input, we obtain:
0.25 M x V2 = 1.00 M x 50 mL
If we simplify, we get:
50 mL = 0.25 M x V2
The result of dividing both sides by 0.25 M is:
V2 = 200 mL

In what type of nucleus is the strong nuclear force greater than theelectrostatic force?O A. Any nucleusOB. A very large nucleusOC. A stable nucleusOD. An unstable nucleus
Answers
Answer:
A. any nucleus.
Explanation:
Let's remember the concepts of strong nuclear force and electrostatic force:
- Strong nuclear force: is the force that keeps the nuclei together (protons and neutrons together).
- Electrostatic force: is the attractive and repulsive forces between particles due to electric charges (positive and negative charges).
We have to take into account that the strong nuclear force is the strongest fundamental force in nature, so this means that the strong nuclear force is greater than the electrostatic force.
Thus, based on this logic, the answer would be that any nucleus has a strong nuclear force that is greater than the electrostatic force, so the answer is A. any nucleus.

The city of Carlsbad in California is considering building a $300 million water-desalination plant. The facility would be the largest in the Western Hemisphere, producing 50 million gallons of drinking water a day – enough to supply about 100,000 homes. This plant, which uses improved membranes and pumping system to bring down the energy cost to $0.90 in electricity to produce 10,000 gallons of water. Suppose the desalination plant is fully operational and you expect to operate it continuously for A0 years, with an estimated salvage value of $20 million. The operating and maintenance costs (excluding energy cost) amount to $15 million the first year and will increase at a rate of 3% per year. If the city plans to sells the water for about $925 per acre-foot (an acre-foot is 325,851 gallons – enough water for four people per year.), can it recover the capital cost and other operating costs? Assume the city’s interest rate for this water project is known to be 6%.
Answers
The initial investment is $300 million, and the project is planned to operate for A0 years with an estimated salvage value of $20 million.
To calculate whether the city can recover the capital cost and other operating costs for the water-desalination plant, you can follow these step-by-step calculations:
Step 1: Calculate the annual revenue from selling water:
First, convert the water production from gallons to acre-feet:
Water production per day = 50 million gallons
Water production per year = 50 million gallons * 365 days = 18.25 billion gallons
Water production in acre-feet = 18.25 billion gallons / 325,851 gallons per acre-foot
Calculate the annual revenue from selling water:
Annual revenue = Water production in acre-feet * Price per acre-foot
Step 2: Calculate the annual operating and maintenance costs (excluding energy cost):
Operating and maintenance costs in the first year = $15 million
Calculate the annual operating and maintenance costs for subsequent years:
Operating and maintenance costs in year n = Operating and maintenance costs in year n-1 * (1 + Growth rate)
Step 3: Calculate the annual energy cost:
Energy cost per 10,000 gallons = $0.90
Calculate the annual energy cost:
Annual energy cost = Water production in gallons / 10,000 gallons * Energy cost per 10,000 gallons
Step 4: Calculate the annual cash flow:
Annual cash flow = Annual revenue - Annual operating and maintenance costs - Annual energy cost
Step 5: Calculate the present value of cash flows:
Use the present value formula to calculate the present value of cash flows over the A0 years:
PV = Annual cash flow / (1 + Interest rate)^Year
Step 6: Calculate the net present value (NPV):
NPV = PV - Initial investment
Step 7: Determine if the project is financially feasible:
If the NPV is greater than or equal to zero, the project is financially feasible and can recover the capital cost and other operating costs. If the NPV is negative, the project may not be able to recover the costs.

48g of Magnesium reacts with excess oxygen to produce 84g of magnesium oxide. Calculate how much magnesium oxide would be produced if 2g, 10, and 4kg were reacted with excess oxygen. 0.4 Moles of iron reacts with 0.3 moles of oxygen gas. Calculate the formula of the ir oxide produced and write a balanced equation for it.
Answers
For 2g of magnesium: 3.31 g
For 10g of magnesium: 16.59 g
For 4kg of magnesium: 6.63 kg
The balanced chemical equation for the reaction is:
2 Mg + O2 → 2 MgO
Step by step explanationThe balanced chemical equation for the reaction is:
2 Mg + O2 → 2 MgO
From the equation, we can see that 2 moles of magnesium react with 1 mole of oxygen to produce 2 moles of magnesium oxide. Therefore, we can calculate the amount of magnesium oxide produced for each given mass of magnesium as follows:
For 2g of magnesium:Moles of Mg = mass / molar mass = 2g / 24.31 g/mol = 0.0823 mol
Moles of MgO produced = Moles of Mg x (2 moles MgO / 2 moles Mg) = 0.0823 mol x 1 = 0.0823 mol
Mass of MgO produced = Moles of MgO produced x molar mass of MgO = 0.0823 mol x 40.31 g/mol = 3.31 g
For 10g of magnesium:Moles of Mg = mass / molar mass = 10g / 24.31 g/mol = 0.4116 mol
Moles of MgO produced = Moles of Mg x (2 moles MgO / 2 moles Mg) = 0.4116 mol x 1 = 0.4116 mol
Mass of MgO produced = Moles of MgO produced x molar mass of MgO = 0.4116 mol x 40.31 g/mol = 16.59 g
For 4kg of magnesium:Moles of Mg = mass / molar mass = 4000g / 24.31 g/mol = 164.47 mol
Moles of MgO produced = Moles of Mg x (2 moles MgO / 2 moles Mg) = 164.47 mol x 1 = 164.47 mol
Mass of MgO produced = Moles of MgO produced x molar mass of MgO = 164.47 mol x 40.31 g/mol = 6626.95 g or 6.63 kg
Calculation of Formula of Iron Oxide Produced:
According to the given information, 0.4 moles of iron reacts with 0.3 moles of oxygen gas. To determine the formula of the iron oxide produced, we need to first balance the chemical equation.
Fe + O2 → FeO
From the balanced equation, we can see that 1 mole of iron reacts with 1 mole of oxygen to produce 1 mole of iron oxide. Therefore, the ratio of moles of iron to moles of oxygen in the reaction is 1:1.
To do this, we can calculate the theoretical amount of moles of oxygen required to react completely with 0.4 moles of iron:
0.4 mol Fe × (1 mol O2 / 1 mol Fe) = 0.4 mol O2

After the removal of carbon, the oxygen in co2 ends up.
a. true
b. false
Answers
The given statement, After the removal of carbon, the oxygen in CO₂ ends up is False.
Carbon dioxide (CO₂) is a compound made up of two elements, carbon and oxygen, in a ratio of one carbon atom for every two oxygen atoms. When carbon dioxide is removed, the oxygen atoms do not remain isolated - instead, they bond with other oxygen atoms from the surrounding environment, forming oxygen gas (O₂).
Oxygen gas is highly reactive and forms strong bonds with other oxygen atoms to form molecules of the natural gas O₂. The result is that the oxygen that was part of the carbon dioxide is no longer present - it has become part of the newly formed oxygen gas molecules.
Oxygen gas is present in the atmosphere and it is highly reactive and mobile, meaning that it can quickly move and form bonds with other elements. When carbon dioxide is removed, the oxygen atoms that were part of the molecule become part of oxygen gas instead, creating molecules of the natural gas O₂.

Keiko will buy more than 9 pounds of candy in order to spend more than $36.
To find the possible numbers of pounds Keiko will buy, we can use the inequality:
4p > 36
where p is the number of pounds Keiko will buy.
Solving for p, we can divide both sides of the inequality by 4:
p > 9
This means that Keiko will buy more than 9 pounds of candy in order to spend more than $36.
Therefore, the possible numbers of pounds she will buy are any number greater than 9, such as 10, 11, 12, and so on.
