What are calibaration of a solution?

Standard addition, internal standard, and external standard techniques to quantitation all employ calibration solutions. Calibrants can be made gravimetrically using reference standards or pure reference materials, but they can also be made on a volumetric or other fraction basis.

For preparing the solution of known concentration and volume, the equation can be related as:

M1v1=M2V2

M1 and V1 are molarity of known solution

M2 AND V2 molarity of solution to be prepared

Here,M1=1 x 10^-4M

        M2= 1 X 10^-5 M

V2= 25ml

1 x 10^-4 x V1=1 X 10^-5 x 25

Volume of required solution=2.5ml

To make the volume 10ml of 3 x 10^-5 x 10

Volume of required solution=3ml

Therefore the volume of solution required to make final concentration of   is 2.5 ml and for   is 3 ml.

the halogens, X2 Draw the molecule by placing atoms on the grid and connecting them with bonds. Include nonbonding electrons. Use X to indicate a halogen atom.

Answers

In a lewis structure of a molecule, we place the valance electrons of the bonded atoms around them.  Then the shared pair or bond pair electrons between the bonded atoms are joined and represented as a line.

whereas the nonbonding electrons called lone pairs are kept as a pair of dots around them. Now we know the valance electrons of any halogen is 7. So each halogen needs only 1 more electron to complete its octet. Hence on X2, each X-atom will share one of the electrons to form a single bond as in the image.

Halogens exist as simple molecules. Each molecule contains two halogen atoms joined by a single covalent bond.

What happens to molecules when they slow down?; What happens if you slow down the particles in a liquid?; When the motion of water vapor molecules slows what most likely happens?; What happens if water molecules are speeded up?

Answers

The attraction between the molecules of a liquid causes them to organize themselves, and this happens when a liquid freezes. As the speed of water molecules rises, increasing their kinetic energy.

The kinetic energy of the liquid decreases as it cools, which causes the molecules to travel more slowly. By slowing the flow and allowing the soil profile to function as a filter, as it always has, it improves the water quality and reduces the amount of toxic algae in our water supplies. Condensation occurs when molecules in a gas cool down. Ice is created when the water's molecules stick together at around 0°C and form a solid. The molecules slow down and lose energy as they lose heat. They advance toward additional gas molecules. In the end, these molecules come together to create a liquid. The temperature of a material is determined by how quickly its atoms and molecules are moving.

Answers

0.357 days is required for the completion of 90% of 1kg 239Pu at the rate-determining step for the reaction of the second B-emission.

What is the rate-determining step?

In chemical kinetics, the slowest step, sometimes referred to as the rate-determining step, or rate-limiting step frequently determines the overall pace of a process. This approximation of the rate-determining step is frequently used to simplify the prediction of the relevant rate equation for a given reaction mechanism (for comparison with the experimental rate law).

The collection of simultaneous rate equations for the various phases of the mechanism can theoretically be used to estimate the temporal evolution of the reactant and product concentrations. However, it is not always simple to solve these differential equations analytically; in some circumstances, numerical integration may even be necessary.  The single rate-determining step hypothesis can be very beneficially simplified.

Calculation:

We know that,

Half-life of 239Pu is 2.35 days

The solution(s) that changed pH the most were those that were just water and a NaCl solution, without any buffers.

What factors into a solution's pH?A pH meter, universal indicator solution, or paper can all be used to determine the pH of a solution. The pH scale measures the amount of H+(aq) ions present in a solution. Although mol dm(-3) can be used to express the concentration of H+ ions, using the log(10) function makes the calculations easier.The pH value drops when a solution's hydrogen ion concentration rises, making the solution more acidic. The pH value also rises as the concentration of hydroxide ions in a solution does, making the solution more basic or alkaline.The solution(s) that changed pH the most were those that were just water and a NaCl solution, without any buffers.

2,4-dinitrophenol uncouples oxidative phosphorylation by decreasing the membrane potential. The process involves inhibiting electron flow from complex to ubiquinone shuttling the protons across the mitochondrial membrane preventing the electron transfer from Fe-S center to ubiquinone inhibiting cytochrome oxidase

Answers

DNP is integrated into mitochondrial membranes, electron transport is gradually inhibited. Dinitrophenol (DNP) is an uncoupler, which means it may separate the pumping of H+ ions for ATP production from the flow of electrons.

Without affecting the respiratory chain or ATP synthase (H(+)-ATPase), uncoupler of oxidative phosphorylation in mitochondria prevent the coupling between the electron transport and phosphorylation reactions. This inhibits ATP synthesis.

DNP is known to have mixed activities, which means that in addition to uncoupling, it also has other effects. This implies that ATP production is not possible using the energy from electron transport.

It is a precursor to other chemicals and is biochemically active, allowing protons to go from the intermembrane space into the mitochondrial matrix to decouple oxidative phosphorylation from the electron transport chain in cells with mitochondria.
