Introduction: The (fictitious) town of Solutionville is trying to figure out a way to replace their current coal-fired power plants with cleaner and more sustainable energy sources. At a recent town meeting, it was proposed that the town build a nuclear power plant to replace coal as the community’s main source of energy for electricity.



Your Challenge: As a voting citizen of Solutionville, you must decide whether or not you support building a nuclear power plant to provide energy and electricity to homes and businesses in the community. This means carefully weighing the benefits and disadvantages of nuclear power.



1. Conduct research to learn more about nuclear power, and keep track of what you learn on slide#4 and/or in your notebook.

2. Make sure to write down the sources you get your information from, and be ready to defend the sources as credible.

3. Using the information you find, fill in the Benefits and Drawbacks Chart on slide #5 3. Be prepared to defend the information on your chart with evidence from your sources.

4. Analyze your findings, then find a partner and compare notes.

5. Decide whether or not you are in favor of or opposed to nuclear energy.

0.092M

Explanation:

Molarity of glucose solution = number of moles ÷ volume

According to this question, 12.5g of glucose (C6H12O6) is dissolved in enough water to make 750mL of solution.

Molar mass of glucose (C6H12O6) = 12(6) + 1(12) + 16(6)

= 72 + 12 + 96

= 180g/mol

mole = mass/molar mass

mole = 12.5/180

mole = 0.069mol

Volume of solution = 750mL = 750/1000 = 0.750L

Hence, molarity = n/V

Molarity = 0.069 ÷ 0.750

Molarity = 0.092M

Answer: No

Explanation:

Epsom salts have different solubility in water compared to sugar.

Answer:

5 milliliters

Explanation:

Use the formula M1V1 = M2V2 where M is molarity and V is volume

Plug in numbers

(.25 M)(100 mL) = (5 M)V2

V2 = 5 mL

The volume of stock solution of 5M H₂SO₄ needed to prepare 100mL of 0.25M H₂SO₄ is 5mL.

Volume of stock solution to prepare any dilute solution will be calculated by using the following formula:

M₁V₁ = M₂V₂, where

M₁ & V₁ is the molarity and volume of stock solution, and

M₂ & V₂ is the molarity and volume of final prepared solution.

On putting values from the question to the above formula and calculate for the value of V₁ as:
V₁ = (0.25)(100) / (5)

V₁ = 5 mL

Hence required volume is 5mL.

Questions about the kind of charge, the magnitude of charge etc can be asked when the charge on an ion is determined.

An ion is a charged atom or a charged molecule. It attains a charged state because the number of electrons does not remain equal to the number of protons in the atom or the molecule.

The gain of a positive charge by an atom or a negative charge will depend on the fact that whether the number of electrons in an atom is greater than the number of protons or less than the number of protons.

If the atom loses electrons, the total proton number will be higher, so the atom will become positive. If the atom gains electrons, the total electron number will be higher, so the atom will be negative.

The attraction of an atom to another atom happens because it has an unequal number of electrons and protons, then the atom is called an ION. If the atom has more electrons than protons, it is a negative ion or ANION. If it has more protons than electrons, it is a positive ion.

Explanation:

Work is a net force applied through a distance in order to displace an object, commonly abbreviated as W. A net force is the sum of all forces acting on an object. Work is mass times acceleration and distance so to find out the work you simply calculate the acceleration of the box being brought in. Next find the distance it was carried to get in the house. Then find out the mass of the box and finally multiply those sums together to get the amount of work put in to bring the package inside.

Explanation:

Hello there!

In this case, according to the Charles' gas law as way to understand the volume-temperature as a directly proportional relationship for this problem, we can write:

[tex]\frac{T_2}{V_2}=\frac{T_1}{V_1}[/tex]

Thus, given the initial temperature and volume and the final volume, we are able to calculate the final temperature as follows:

[tex]T_2=\frac{T_1V_2}{V_1} \\\\T_2=\frac{252K*5.25L}{3.90L}\\\\T_2=339K[/tex]

Answer:

The correct option is option;

A. 1.58 mol

Explanation:

The given balanced chemical reaction is presented as follows;

2Al₂O₃ → 4Al + 3O₂

The given mass of Al produced = 85.5 grams

The given molar mass of Al₂O₃ = 85.962 g/mol

The given molar mass of O₂ = 31.998 g/mol

The given molar mass of Al = 26.982 g/mol

[tex]We \ note \ that \ the \ number \ of \ moles, \ n = \dfrac{Mass }{Molar \ mass}[/tex]

For the given produced Al, n = 85.5 g/(26.982 g/mol) ≈ 3.169 moles

From the given reaction, we have;

2 moles of Al₂O₃ produces 4 moles of Al

∴ 2/4 moles of Al₂O₃ produces 4/4 = 1 mole of Al

2/4 × 3.169 = 1.5845 moles of Al₂O₃ produces 1 × 3.169 = 3.169 moles of Al

∴ 1.5845 ≈ 1.58 moles of Al₂O₃ produces 3.169 moles of Al ≡ 85.5 grams of Al

The correct option is approximately 1.58 moles of Al₂O₃.

Q.1

Given-

Volume of solution-1 L

Molarity of solution -6M

to find gms of AgNO3-?

Molarity = number of moles of solute/volume of solution in litre

number of moles of solute = 6×1= 6moles

one moles of AgNO3 weighs 169.87 g

so mass of 6 moles of AgNO3 = 169.87×6=1019.22

so you need 1019.22 g of AgNO3 to make 1.0 L of a 6.0 M solution

1. the grams of [tex]\rm AgNO_3[/tex] is 1019.22.

2. 10,192.2

Molarity is the measure of the concentration of any solute in per unit volume of the solution.

1. Volume is 1.0 l.

Molarity of solution -6 m

To find the mass of [tex]\rm AgNO_3[/tex]

[tex]\rm Molarity = \dfrac{n}{V}\\\\rm 6 = \dfrac{n}{1}\\\\n = 6 \times 1 = 6[/tex]

Mass of One mole of [tex]\rm AgNO_3[/tex] is 169.87 g

Therefore, the mass of 6 moles will be

169.87 × 6 = 1019.22

2. Molarity of solution 6.0

Volume of solution is 0.1m

The mass of 6 moles will be

169.87 × 6 = 1019.22

[tex]\rm density = \dfrac{mass }{volume} \\\\\rm density = \dfrac{1019.22 }{0.1} = 10,192.2[/tex]

Thus, the options are 1. 1019.22    2. 10,192.2

Explanation:

This is an extension of Graham's Law of Effusion where [tex]\frac{R1}{R2} = \sqrt{\frac{M2}{M1} } = \frac{t2}{t1}[/tex]

We're only talking about molar mass and time (t) here so we'll just concentrate on [tex]\sqrt{\frac{M2}{M1} } = \frac{t2}{t1}[/tex]. Notice how the molar mass and time are on the same position, recall effusion is when gas escapes from a container through a small hole. The time it takes it to leave depends on the molar mass. If the gas is heavy, like Xe, it would take a longer time (4.83 minutes). If it was light it would leave in less time, that gives us somewhat an idea what our element could be, we know that it's atleast an element before Xenon.

Let's plug everything in and solve for M2. I chose M2 to be the unknown here because it's easier to have it basically as a whole number already.

[tex]\sqrt{\frac{M2}{131} } = \frac{2.29}{4.83}[/tex]

The square root is easier to deal with if you take it out in the first step, so let's remove it by squaring each side by 2, the opposite of square root essentially.

[tex](\sqrt{\frac{M2}{131} } )^2= (\frac{2.29}{4.83})^2[/tex]

[tex]{\frac{M2}{131} } = (0.47)^2[/tex]

[tex]{\frac{M2}{131} } = 0.22[/tex]

M2= 0.22 x 131

M2= 28.93 g/mol

Answer:

The reaction takes place is

 2 (C2H6) + 7 (O2) → 4(CO2) + 6(H2O) 

According to the equation,

60g ethane requires 7x32= 224g oxygen

here ethane is in excess.oxygen will be consumed completely.

hence

2.9 g O2 will consume 60×2.9/224=0.776g of C2H6

now,

2 moles of C2H6 produces 4 moles of CO2!

60g ethane produces 4x44 g CO2

hence amount of CO2 produced =4×44×0.776/60=2.27g

Answer:

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Lithium, or 6.941 grams.

"Electron binding energy, more commonly known as ionization energy, is a measure of the energy required to free an electron from its atomic orbital or from a solid. ... The atomic binding energy of the atom is the energy required to disassemble an atom into free electrons and a nucleus."

Explanation:

Hope this helps! <33

God bless your heart <3333

have a wonderful day!

Binding energy is a required amount of energy that disperses the other particles of the reaction system. It measures the energy needed to free an electron or a subatomic particle.

Binding energy is the ionization energy that depicts how much energy will be needed if an electron has to be removed from an atom for a reaction to occur.

It can be said that the energy required to free an electron from the orbit of the atom is measured in electron volt (eV). It is a little different from ionization energy as binding energy can remove any subatomic particle and not just an electron.

Therefore, the binding energy measures the freed subatomic particle.

Answer:

1514g of CO₂ reacted

Explanation:

Based on the reaction:

2CO₂ + 43.9kJ → 2CO + O₂

2 moles of carbon dioxide require 43.9kJ of energy to produce 2 moles of carbon monoxide and 1 mole of oxygen

To solve this question, we must convert the 755kJ of energy to moles of carbon dioxide that reacts and to find the mass as follows:

755kJ * (2 moles CO₂ / 43.9kJ)  =34.4 moles of CO₂ are produced
