C. Energy/amu for proton-proton is 0.36 and for fission it is 0.85106383.

D. Based on my work from C, does fission or fusion release the most energy per amu?

Answer:

if you mutliply 8x2 it would be 16 and half of 16 is 8 and if you multiply that by 2 you get 16 again and then if you multiply that by 2 it comes out to 32 then devide that by 2 and you get 16 then divide again and you get 8

Developing work ethics won't lower your stress although it may make your conscience a little happier. Not B

Not C. Procrastinating just makes things harder. The mountain of things to do is not diminishing at all and your stress knows it.

Not D. Although D is the second best answer, setting goals is not really an action. It is a plan for how to work. But it is not work. Still having a goal is useful.

The answer is A. Just keep hitting what you have to do at a steady pace.

The correct IUPAC name for this compound as described here is 2-methylpropane.

The term IUPAC nomeclature refers to the generally accepted pattern for the naming of compounds. The international Union of Pure and applied chemistry (IUPAC) provides the guidelines for naming compounds. This system of nomenclature helps us to be able to write the unique name of a compound from its structure.

In the system of IUPAC, the parent name is the longest chain in the compound. The substituents are then given numbers in alphabetical order.

Now, the correct IUPAC name for this compound as described here is 2-methylpropane.

Litmus is an example of an indicator, a substance that changes color depending on its pH (pH is a measure of the concentration of protons, or H+ ions). In the Titration Gizmo™, you will use indicators to show how acids are neutralized by bases, and vice versa.

To begin, check that 1.00 M NaOH is selected for the Burette, Mystery HBr is selected for the Flask, and Bromthymol blue is selected for the Indicator.

Calculate: Concentration is measured by molarity (M), or moles per liter. Brackets are also used to symbolize molarity. For example, if 0.6 moles of HNO3 are dissolved in a liter of water, you would say [HNO3] = 0.6 M.

Because HNO3 is a strong acid, it dissociates almost completely in water. That means the concentration of H+ is very nearly equal to that of HNO3.What is [H+] if [HNO3] is 0.01 M? 0.01 M

The pH of a solution is equal to the negative log of H+ concentration: pH = –log[H+]

Describe: The equation for the reaction of nitric acid (HNO3) and sodium hydroxide (NaOH) is shown on the bottom right of the Gizmo.

Measure: A titration can be used to determine the concentration of an acid or base by measuring the amount of a solution with a known concentration, called the titrant, which reacts completely with a solution of unknown concentration, called the analyte. The point at which this occurs is called the equivalence point.

Explain: A titration curve is a graph of pH vs. volume of titrant. The graph at right shows a typical titration curve for the titration of a strong acid by a strong base. (A strong base is one that has relatively high dissociation in water.)

According to theBrønsted-Lowry definition, an acid is a substance that is capable of donating a proton to another substance. A base is a substance that accepts protons. When an acid and a base are combined, the acid is neutralized as the base accepts the protons produced by the acid.One way to determine if a solution is acidic or basic is to use litmus paper, as shown above. There are two types of litmus papers: red and blue.How does litmus paper indicate an acid? Both strips turn red.

Mass of chlorine

941539.2 g of mass of oxygen is produced when 2000 kg of aluminium oxide is completely electrolysed.

Electrolysis is the process by which electric current is passed through a substance to effect a chemical change.

The mass of aluminium oxide Al₂O₃ = 2000 kg = 2000 000 g

Molar mass of Al₂O₃ = 101.96 g/mol

no of moles = [tex]\frac{mass }{ molar \;mass}[/tex]

no of moles of Al₂O₃ =  [tex]\frac{2000 000 g}{101.96 g/mol}[/tex]

no of moles of Al₂O₃ = 19615.4 mol

From the reaction:

4Al + 3O₂  ⇒  Al₂O₃

To determine the moles of O₂ in Al₂O₃:

Then;

19615.4 mol X [tex]\frac{3}{2}[/tex] mol of O₂ = 29423.1

The mass of oxygen now = 29423.1  × 32 g

= 941539.2 g

Hence,  941539.2 g of mass of oxygen is produced when 2000 kg of aluminium oxide is completely electrolysed.

The energy released in nuclear reactions are far larger than that released in chemical reactions due to the release of nuclear energy from the nucleus.

Energy is released in a reaction due to the breaking of bonds are well as formation of bonds.

The quantity of energy released in reactions differs according to the reaction type involved.

When compared to chemical reactions, the energy released in nuclear reactions are very much higher because of the changes that occurs in the nucleus of the atoms involving nuclear energy.

The energy, E released in nuclear reactions is given by the formula below:

[tex]E = mc^{2}[/tex]

where m is the mass of the substance and c is the speed of light.

Which of these solutions is the most basic?

[OH-] = 4.3 x 10-9 M

[OH-] = 2.8 x 10-11 M

[OH-] = 6.7 x 10-10 M

[OH-] = 1.0 x 10-5 M

[OH-] = 4.3 x 10-9 M

_______________________________________

[OH-] = 2.8 x 10-11 M

_______________________________________

[OH-] = 6.7 x 10-10 M

_______________________________________

[OH-] = 1.0 x 10-5 M

_______________________________________

we know that , the solution with pH > 7 is termed as basic and more the pH ,more the basicity, hence ,the solution with the highest pH would be the strongest base out of these all which is

[OH-] = 1.0 x 10-5 M with pH = 9

Note the rule

And we can find the answer through logarithm rules basic

So

Higher the n higher the pOH

But

As we can see

Option D has least n (5)

Hence D is more basic

Answer:

1.99 M

Explanation:

It gives the mass of a compound, KNO3. First, find the gram formula mass of KNO3. You should get 101.102 g/mol, or something very close. Next, divide given mass by g/mol mass to get number of moles. In this case, 45.3/101.102 = .44806, roughly.

Now, since it says molar concentration, it is asking for moles per liter of solution. If it only gives you 225 mL, or .225 L, you have to adjust for that value. Divide the number of moles you have by number of liters.

.44806/.225 = 1.99 M. This isn't the exact answer, but always remember to round for significant figures. Since both numbers contain 3 significant figures, your answer should have 3. Therefore 1.99 is your answer.
