when using a ph meter to monitor a stirring reaction mixture, where should you place the ph sensor electrode?

Answers

Answer 1

Answer:Between the stirring vortex and the side of the glassware

Answer 2

When using a ph meter to monitor a stirring reaction mixture, the ph sensor electrode

should be placed;

between the stirring vortex and the side of the glassware.

The pH meter is an electric device that is used to measure the hydrogen-ion activity in water-based solutions. This means that it is used to measure the PH which is the acidity or alkalinity.

The pH meter is made up of a voltmeter attached to a pH-responsive electrode and a reference electrode.

Now, this pH-responsive electrode is usually made of glass while the reference electrode is usually a silver–silver chloride electrode.

Now when monitoring the stirring reaction mixture, the PH-responsive electrode written above is usually placed between the stirring vortex and the side of the glassware.

You have been handed a 1892.6g sample of Rion and determine that it has
a volume of 200.0 mL. What is the density of Rion?

Answers

Answer:

9.46 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 1892.6 g

volume = 200 mL

We have

[tex]density = \frac{1892.6}{200} \\ = 9.463[/tex]

We have the final answer as

9.46 g/mL

What is solar system?

Solar system is defined as the grouping of the eight planets and their moons in orbit around the sun, as well as other smaller bodies like comets, asteroids, and meteoroids.

It can also be defined as the Sun's orbiting objects are confined by gravity to one system.

An orbiting collection of planets, meteors, or other celestial bodies is referred to as a star system.
The Sun, an ordinary star, the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto make up our solar system.

Our solar system is referred to as the "solar system" because our Sun is called Sol after the Latin word for Sun, "solis," and because anything related to the Sun is termed "solar."

Thus, scientists work independently to form theories about the Earth without sharing data.

why should you never place a hot object on the pan of a balance

Answers

Answer:

Because, it would make the pan hot and if it's plastic then it would melt. if it was metal it might make the metal piece hot and you'd risk burning yourself.

Explanation:

You should never place a hot object on the pan of a balance because it can cause the balance to become inaccurate and affect the measurement results.

Balances are precision instruments used to measure the mass of objects with high accuracy. The balance pan and its components are designed to operate under specific conditions, including a stable temperature. When you place a hot object on the balance pan, several issues can arise:

Thermal Expansion: Materials, including metals and plastics, can expand when exposed to heat. Placing a hot object on the pan can cause the pan and its supporting components to expand, potentially affecting the balance's calibration and accuracy.

Uneven Heating: If the hot object is not uniformly heated, it can cause uneven expansion of the balance pan. This can lead to imbalanced weight distribution and inaccurate measurements.

Calibration Shift: The heat from the hot object can cause the materials in the balance to change temperature rapidly, potentially affecting the calibration of the instrument. The balance may require time to stabilize before accurate measurements can be obtained.

Damage to the Balance: Exposing the balance pan to extreme heat can cause warping, cracking, or other structural damage to the pan material. This can permanently impair the balance's performance and accuracy.

To ensure accurate measurements and maintain the integrity of the balance, it's important to allow hot objects to cool to room temperature before placing them on the balance pan. Additionally, using appropriate containers or holders designed for high-temperature applications can help prevent damage to both the hot object and the balance equipment.

Answers

Answer:

1. D 2.. A 3. C 4. B

Explanation:

just took the quiz

We can classify each rock as intrusive or extrusive and basaltic or granitic as follows; Rock A - Extrusive, Basaltic, Rock B - Intrusive, Granitic, Rock C - Extrusive, Basaltic, and Rock D - Extrusive, Basaltic.

Rock A - Extrusive, Basaltic

Rock A is described as having dark-colored large grains, which indicates a fine-grained texture, typical of extrusive rocks. The presence of dark-colored large grains suggests a basaltic composition.

Rock B - Intrusive, Granitic

Rock B is described as having large crystals and a high percentage of silica, which suggests a coarse-grained texture, typical of intrusive rocks. The high silica content and large crystals indicate a granitic composition.

Rock C - Extrusive, Basaltic

Rock C is described as having a fine-grained texture and being light-colored, which are characteristic features of extrusive rocks. The fine-grained texture suggests a rapid cooling, typical of extrusive rocks, and the light color is indicative of a basaltic composition.

Rock D - Extrusive, Basaltic

Rock D is described as being from the Hawaiian volcano area and having no visible crystals. This indicates a glassy texture, typical of rapidly cooled extrusive rocks. The origin from a volcanic area and glassy texture suggest a basaltic composition.
