Find the pH during the titration of 20.00 mL of 0.1000 M butanoic acid, CH₃CH₂CH₂COOH (Kₐ = 1.54X10⁻⁵), with 0.1000 M NaOH solut
tensa zangetsu [6.8K]

Ph range is 14.35.

<h3>What is PH?</h3>

PH is a proportion of hydrogen particle focus , a proportion of the causticity or alkalinity of an answer. The pH scale for the most part goes from 0 to 14. Fluid arrangements at 25°C with a pH under 7 are acidic, while those with a pH more prominent than 7 are essential or basic. Having a reasonable pH safeguards our bodies from the back to front. Some even say that illnesses and problems can't fill in a body whose pH is in balance. The pH is a logarithmic scale, that is to say, when an answer becomes multiple times more acidic, its pH diminishes by one. In the event that an answer becomes multiple times more acidic, its pH will diminish by two. The pH scale is recognizable to a bunch of standard arrangements whose pH is laid out by peaceful accord. Essential pH standard qualities are resolved utilizing a fixation cell with transaction, by estimating the possible distinction between a hydrogen terminal and a standard cathode like the silver chloride anode.

What process is required for minerals to crystallize from magma
OleMash [197]

Answer:

Chemical differentiation

Explanation:

The process by which minerals crystallize out of magma is termed chemical differentiation. Some times, it is referred to as magmatic differentiation.

  • Minerals have different properties and at certain environment, it comfortable for the settle out of magma.
  • Some minerals can crystallize out at very high temperature.
  • Some will form at medium temperature whereas, some are low temperature minerals.
  • Based on the properties of the minerals in a melt, a minerals will differentiate at various temperature and pressure regimes.

A sound wave has a wavelength of 0.450
Karolina [17]

Answer:

The wave's frequency is <u><em>733 hertz</em></u>.

Explanation:

The wavelength (λ) is the minimum distance between two points of the wave that are in the same state of vibration.

Frequency (f) is the number of vibrations that occur in a unit of time.

The speed of propagation (v) is the speed with which the wave propagates in the middle. Relate wavelength (λ) and frequency (f) inversely proportionally using the following equation: <em>v = f * λ</em>.

In this case you know that:

  • Wavelength of the sound wave (λ) = 0.450 meters
  • Speed of the sound wave (v)= 330 meters per second= 330 \frac{meters}{second}

Replacing you get:

330 \frac{meters}{second} = f* 0.450 meters

Then:

f=\frac{330 \frac{meters}{second} }{0.450 meters}

f=733.33 hertz≅733 hertz

Finally,  <u><em>the wave's frequency is 733 hertz.</em></u>

A 85.4 lb child has a Streptococcus infection. Amoxicillin is prescribed at a dosage of 45 mg per kg of body weight per day give
bixtya [17]

The amount of Amoxicillin dose given to the 85.4 lb child daily is determined as 1,743.3 mg.

<h3>What is the amount of Amoxicillin dose given to the child?</h3>

The amount of  Amoxicillin  dose given to the child is calculated as follows;

amount of Amoxicillin dose = weight of the child x dosage prescribed

<h3>What is the weight of the child in pounds (lb) </h3>

The weight of the child in pounds (lb) is calculated as follows;

1 lb = 0.453592 kg

85.4 lb = ?

= 85.4 x 0.453592 kg

= 38.74 kg

amount of Amoxicillin dose = 38.74 kg x 45 mg/kg

amount of Amoxicillin dose = 1,743.3 mg

Thus, the amount of Amoxicillin dose given to the 85.4 lb child daily is determined as 1,743.3 mg.
