Wavelength is chosen by analyzing the spectrogram.
Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave.
A spectrogram gives a going for walks show of a sound signal because it takes place in real time, a spectrum, however, offers us a photograph of the sound at a particular factor in time. A spectrum can permit you to see.
Spectrograms map out sound in a comparable way to a musical rating, only mapping frequency rather than musical notes. Seeing frequency energy allotted over the years in this manner allows us to genuinely distinguish each of the sound factors in a recording, and their harmonic shape.

increased co2 in the atmosphere since the industrial revolution has resulted in lower surface ocean ph of about ph units.
Since the start of the industrial revolution more than 200 years ago, human activity has led to an increase in the atmospheric concentration of carbon dioxide (CO2). The pH of the ocean's surface waters has decreased by 0.1 pH units throughout this time.
As a result of the rise in atmospheric CO2 concentrations, the pH of the ocean surface has decreased over the industrial age, falling from 8.2 to below 8.1. This drop is accompanied by a 30% increase in oceanic acidity.It first creates carbonic acid. The carbonic acid then "dissociates," or separates, into bicarbonate ions and hydrogen ions. Ocean acidification is caused by an increase in hydrogen ion concentration and a decrease in carbonate ions as a result of increasing CO2 absorption.What is the meaning of Industrial Revolution ?A significant and swift transition in an economy (as in late-18th-century England) signaled by the widespread adoption of power-driven machinery or by a significant shift in the prevalent forms and applications of such machinery.

if you compared 1m solutions, was a 1m nacl solution less hypertonic than a 1m sucrose solution? what is you evidence? what about 1m nacl and 1m glucose and 1m sucrose?
If you compare 1 M Nacl solution, 1M glucose solution and 1M sucrose solution,1M Nacl solution is more hypertonic due to the dissociation of ions in the solution.
Of the two solutions the solution with higher osmotic pressure is called hypertonic. The extra pressure developed on the solution side due to the diffusion of solvent from its high amount through a semipermeable membrane is called the osmotic pressure.
Osmotic pressure= icRT
Where, i= van't hoff factor
c= concentration
R=Gas constant
t= temperature
The extent of dissociation or association of a solute in solution is expressed in terms of the van't hoff factor.
In 1M Nacl, as Nacl dissociates into ions in the solution its van't hoff factor becomes 2. In 1 M glucose it doesn't dissociate into ions. So van't hoff factor remains 1. And In 1 M sucrose,as it does not dissociate into ions van't hoff factor remains 1. So here Nacl has more osmotic pressure.
So, Nacl is hypertonic because of its dissociation into ions in the solution.

Explanation:
when temperature and pressure are held constant, volumes can be used in gas-phase reaction stoichiometry because
Because of Avogardo Hypothesis, volumes can be used in gas phase reaction stoichiometry at constant temperature and pressure.
Avogadro's Law (also known as Avogadro's Hypothesis or Avogadro's Principle) is an experimental gas law that relates the volume of gas to the amount of gaseous matter present.
Avogadro's law states that "equal volumes of all gases at the same temperature and pressure have the same number of molecules". At constant temperature and pressure, (mol) of a gas is directly proportional.
For example, if two ideal gases, hydrogen and nitrogen, are mixed in equal amounts, they contain the same amount of molecules. This only happens if they are kept at the same pressure and temperature. This shows the ideal behavior of gases.
Let's look at this law mathematically: the overall law can be written as
V is directly proportional to n
or V = nK , K (a constant)
Amount of gas; “n” is the gaseous substance measured in moles. "k" is a constant defined for a specific pressure and temperature.
Comparing the same gas under different conditions, the law is : V₁/ n₁=V₂/ n₂
The equation shows that the number of moles of gas increases in proportion to the increase in gas volume. Therefore, the total number of atoms or molecules present in a given volume of gas is completely independent of the molar mass or size of the gas.

1) H2(g)+I2(g)⇌2HI(g). Why does the reaction occur only in the forward direction at first?
2) During the reaction, how does the rate of the forward direction compare to the rate of the reverse direction?
The reaction has a low activation energy and mostly of the reactants are converted into products hence the reaction tends to occur in the forward direction
2) The rate of the reverse reaction is too small compared to the rate of the forward reaction.
What is the reaction?The term reaction has to do with the interaction that occurs between the reactants and the products. Thus as the reactants interacts, a new substance is formed and then we have new substances and they are called the products. Looking at the reaction as it is written in question (1), we can see that the there is a complete and total interaction that occurs as all the reactants are converted into products. Given the fact that all the reactants are converted into products, the reactions can only proceed forward.
In this reaction, we can see from the equation that the reaction is reversible. This means that the reaction is able to occur in both directions; forward and backwards. This reactions proceeds mostly forward hence the rate of reverse reaction is infinitesimal compared to the rate of the forward reaction.

A 40.0 ml sample of 0.25 m KOH is added to 60.0 ml of 0.15 m Ba(OH)₂. the molar concentration of OH⁻ ion in the resulting solution is 0.28 M.
Given that :
volume of KOH = 40 mL = 0.04 L
Molarity of KOH = 0.25 M
volume of Ba(OH)₂ = 60 mL = 0.06 L
molarity of Ba(OH)₂ = 0.15 M
moles of OH⁻ in KOH = 0.04 × 0.25 = 0.01
moles of OH⁻ in Ba(OH)₂ = 2 (0.06 × 0.15) = 0.018
total no. of moles = 0.01 + 0.018 = 0.028 mol
total volume = 0.04 + 0.06 = 0.1 L
molarity of OH⁻ ion = moles / volume
