Answer:

Explanation:

The concentration of 25 mL of potassium hydroxide can be determined from 0.1 M solution of hydrobromic acid by titration.

Titration involves the process by which the concentration of an unknown solution is determined by reaction a known volume of the unknown solution with a carefully measured volume of a standard solution. By determining the volume of the standard solution required to react completely with the solution of unknown concentration, its concentration can be accurately determined by calculation.

In order to determine the concentration of  25 mL of potassium hydroxide, this volume of solution is put into a conical flask and titrated against a known volume of 0.1 M solution of hydrobromic acid. At the end point, usually signified by a color change, the concentration of the 25 mL of potassium hydroxide solution can be calculated from the stoichiometry of the reaction.

Taking into account the definition of dilution,  the new concentration of the solution is 0.2567 M.

First of all, you have to know that   dilution is the reduction in concentration of a chemical in a solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volumeof the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you know:

Replacing in the definition of dilution:

0.385 M× 0.600 L= Cf× 0.900 L

Solving:

Cf= (0.385 M× 0.600 L)÷ 0.900 L

Cf= 0.2567 M

In summary, the new concentration of the solution is 0.2567 M.

The energy range expected is 6.6 × 10^-19 J < E < 7.33 × 10^-19 J

The energy of the photon is given by;

E = hc/λ

E = energy of the photon

h = Plank's constant

c = speed of light

λ = wavelength of light

For the upper boundary range;

E = ?

h = 6.6 × 10^-34 Js

c = 3  × 10^8 m/s

λ = 270 × 10^-9

E =  6.6 × 10^-34 Js × 3  × 10^8 m/s / 270 × 10^-9

E = 7.33 × 10^-19 J

For the lower range;

E = ?

h = 6.6 × 10^-34 Js

c = 3  × 10^8 m/s

λ =300 × 10^-9

E =  6.6 × 10^-34 Js × 3  × 10^8 m/s / 300 × 10^-9

E = 6.6 × 10^-19 J

Hence, the energy range 6.6 × 10^-19 J < E <  7.33 × 10^-19 J

Explanation:

The biggest change in the body caused by regular exercise is to muscle tissue. ... At the cellular level, exercise triggers the release of substances that dilate the blood vessels in the muscle, letting in more oxygen, says Prof Bradford. These are short-term effects, but deeper changes come with regular exercise.

Exercising causes changes in our body because we're working our muscles so there's more going on with us compared to when we're just laying down. We need more oxygen to go to our muscles so we breathe harder and more rapidly. Our heart also beats faster because it needs to pump more blood to the muscles that are being worked.
