Answer:

C2= 0.126M

Explanation:

C1*V1=C2*V2

C1= 0.630M

C2=?

V1= 100.0ML

The correct statement in regards to nuclear fusion are 1) Only in the sun's core does fusion take place because of the necessary temperatures.

2) The three types of neutrinos oscillate one after the other.

3) It takes very high temperatures for nuclei to merge.

The Sun and other stars are powered by nuclear fusion reactions. A heavier nucleus is created when two light nuclei fuse together in a fusion reaction. Because the mass of the resulting single nucleus is smaller than the combined mass of the two initial nuclei, the process produces energy. Remaining mass is converted to energy.

Controlled nuclear fission reactions and chemical reactions like burning coal, oil, or gas each produce roughly four million times as much energy as controlled atom fusion (at equal mass).

To use the van der Waals equation to determine the pressure of a gas if it were behaving ideally, you will need to first determine the value of the a and b parameters for the gas. These values are specific to each gas and can be found in a table or by using a calculator. Once you have the values of a and b, you can use the van der Waals equation to calculate the pressure:

P = (nRT)/(V-nb) - a(n²)/(V²)

where P is the pressure, n is the number of moles of the gas, R is the ideal gas constant, T is the temperature in kelvins, V is the volume of the container, and a and b are the van der Waals parameters for the gas.

Plugging in the given values, you can calculate the pressure of the gas if it were behaving ideally:

P = (3.220 moles × 8.314 J/mol × K × 298 K)/(8.325 L - 3.220 moles × b) - a(3.220 moles²)/(8.325 L²)

monohalogenated alkane is a haloalkane containing only one halogen atom - correct statement.

what is monohalogenated alkane ?

A halogenation reaction is a chemical reaction that takes place between a material and a halogen in which one or more halogen atoms are integrated into the substance's molecules.

When an alkane is halogenated, a hydrocarbon derivative is formed in which one or more halogen atoms are replaced for hydrogen atoms.

Because they are non-polar and lack functional groups where reactions might occur, alkanes are famously unreactive molecules. As a result, free radical halogenation provides a mechanism for functionalizing alkanes.

The amount of identical C-H bonds found in all but the simplest alkanes, however, is a significant constraint of radical halogenation, making selective reactions difficult to execute.

Monohalogenated alkane: An alkane substituted with one halogen atom instead of a hydrogen atom at any position in the compound.

The oxidation number for iron is on the right side of the reaction arrow,

Electron Transport Chain or Oxidative phosphorylation is a series of reductions and oxidation reactions to yield ATP, high energy molecules.

The enzyme, which plays a crucial role in creating proton gradient is ATP synthase. The conversion of ADP to ATP releases energy.

In the given chain, coenzyme Q couples with Cytochrome C for the conversion of ADP to ATP.

The species FADH₂ has oxidized and lost the protons to coenzyme Q. The FADH₂ will be converted to FAD.

FADH₂ + Q  FAD + QH₂

In the reaction, the enzyme has gained electrons, therefore undergone reduction.

As we know, cytochrome C is the iron-containing enzyme, which is represented as Fe ³⁺. It is present on the reactant side, such that:

The coefficient of Fe ³⁺ is 2. The reaction is given as now:

QH₂ + 2 cyt c (Fe ³⁺) - Q + 2 cyt c (Feˣ ) + 2H⁺

Charge present on the reactant side = 2 x 3 =+6

Also, the species on the product side and the reactant side should have an equal number of charges.

Now, following the law of conservation of mass:

QH₂ + 2 cyt c (Fe ³⁺) - Q + 2 cyt c (Feˣ ) + 2H⁺

From the law, the charge on the product side = Charge on the reactant side

2 x + (+2) = +6

x = 6 - 4

x = 2

Thus, the equation becomes:

QH₂ + 2 cyt c (Fe ³⁺) - Q + 2 cyt c (Fe²⁺ ) + 2H⁺

Therefore, the iron ions have a total of +4 charges and the +2 charges have been contributed by the hydrogen ions on the product side.

The stoichiometric coefficient determines the number of iron ions on the product side is 2, thus, the value of x = +2.

As it happens, early human embryos do have slits in their necks that look like gills. This is almost certainly because humans and fish share some DNA and a common ancestor, not because we go though a “fish stage” when in our mothers' wombs as part of our development towards biological perfection

Ancestral characters are often, but not always, preserved in an organism’s development. For example, both chick and human embryos go through a stage where they have slits and arches in their necks like the gill slits and gill arches of fish. These structures are not gills and do not develop into gills in chicks and humans, but the fact that they are so similar to gill structures in fish at this point in development supports the idea that chicks and humans share a common ancestor with fish. Thus, developmental characters, along with other lines of evidence, can be used for constructing phylogenies.

If Iron(III) oxide reacts with nitric acid to produce iron(III) nitrate and water. when 87.3 g of iron(III) oxide reacts with 126.5 g of nitric acid to produce 140.1 g of iron(III) nitrate. The percent yield of the reaction should be 82.5 %.

The balanced reaction is :

Fe₂O₃ + 6HNO₃ → 2Fe(NO₃)₃ + 3H₂O

Moles of Fe₂O₃ taken = (87.3 g) / (160 g/mol)

                                    = 0.545 mol

Moles of HNO₃ taken = (126.5 g) / (63.0 g/mol)

                                    = 2.01 mol

 0.545 mol Fe₂O₃ → 6 × 0.545 mol HNO₃

                          = 3.27 mol HNO₃

But we have only 2.01 mol HNO₃, so HNO₃ is the limiting reagent.

Theoretical moles of Fe(NO₃)₃ formed = [tex]\frac{2}{6}[/tex] × 2.01 mol

                                                          = 0.67 mol

Theoretical yield of Fe(NO₃)₃ = 0.67 mol × 242 g/mol

                                                 = 162.1 g

Percentage yield = (Actual yield / Theoretical yield) × 100

                             = [tex]\frac{133.7 g}{162.1 g}[/tex] × 100

increasing concentration of dissolved CO₂ raises the acidity of ocean water.

The pH of the ocean (a measurement of how acidic or basic the ocean is) decreases when carbon dioxide dissolves in the water, making the water more acidic. Despite the ocean's size, too much carbon dioxide may have a significant effect.

As atmospheric CO₂ levels rise, carbon dioxide dissolves in water to generate carbonic acid (H₂CO₃), which contributes to the acidification of the oceans.

As temperatures increase, carbon dioxide pours out of the ocean like a glass of root beer on a hot day. Deeper waters, which are rich in carbonate dissolved from limestone and other rocks, must be up welled in order to replenish carbonate, which depletes and must be replenished.

Carbon dioxide behaves like the glass windows in a car with the windows wound up in that it allows light to pass through but prevents heat from passing through. This is because carbon dioxide molecules are transparent to visible light but opaque to infrared radiation, which is the type of electromagnetic radiation that is responsible for heat transfer. When light from the sun hits the Earth's atmosphere, the carbon dioxide molecules in the atmosphere allow the light to pass through and reach the surface of the Earth. However, when the heat from the sun's rays is absorbed by the Earth's surface, the carbon dioxide molecules in the atmosphere prevent the heat from escaping back into space, trapping it in the atmosphere and contributing to the greenhouse effect.
