when using a ph meter to monitor a stirring reaction mixture, where should you place the ph sensor electrode?
Answer:Between the stirring vortex and the side of the glassware
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.

Answer:
A. A cell with a negative cell voltage
Explanation:
other answer is wrong
An electrolytic cell is a cell with a spontaneous redox reaction (option B).
What is an electrolytic cell?Electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur.
An electrolytic cell converts electrical energy into chemical energy. The redox reaction in the cell occurs spontaneously and is responsible for the production of electrical energy.
Therefore, according to this question, option B is correct.

Answer:
94448421.2201
Explanation:
multiply the value in kilometers by the conversion factor '0.62137119223684'.
So, 152000 kilometers = 152000 × 0.62137119223684 = 94448.42122 miles.

Max Plank created the idea of quanta4 or quantum energy. This is?
Answer:
A theory of physics in which energy exists only in discrete quantities, called quanta. It was originated in 1900 by the German physicist Max Karl Ernst Ludwig Planck (1858–1947), who suggested that electromagnetic radiation is quantized, i.e. it can be emitted or absorbed only in tiny packets, not continuously.

Physical Models Activity (I need help)
You have explored some interesting, informative, and amusing examples of models. Now it's time to get creative and make your own model. Here is the requirement checklist for your model:
✔ Model types can include drawings, diagrams, physical models, virtual simulations, or videos.
✔ Models must be created by you, not something selected from an online or outside source.
✔ Submit a presentation, picture, video, or screenshot of your model.
✔ Submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. It is important that you are using science terminology and are accurate.
Now that you know how to create and submit your model, you will need to choose a topic for your model. Choose one of the three topics listed below. Select each topic for an overview.
Conservation of Mass
Atomic Theory
Thermal Energy
The question above wants to assess your ability to create a model to represent a scientific concept. In that case, I can't create the model for you, but I'll show you how to create that template.
First, you must choose one of the topics presented in the question. I suggest that you choose the topic "Conservation of Masses," because of its simplicity, however you should choose the one you are most familiar with.
Next, you should research this topic and look at the factors that make it up.
After that, you can create your template as follows:
Use a software that has ready-made drawings, mainly geometric figures, for you to represent the elements that make up this topic.Use these drawings to represent these elements, place titles that identify them, and add arrows, which direct the viewer's attention to understand the model.You can see examples of "Conservation of Masses," models in the attached figure.

Determine mass contribution for the following isotopes of the same element.
At the end, tell me the atomic mass of the element using the mass contributions.
Do not forget your units or the question will be marked incorrect.
Isotope 2 amu: 186.956
percent abundance: 62.6%
Atomic Mass of the element ?
Answer: Not possible to find average amu with only the information provided.
Explanation:
Is there more information about the other isotopes? I don't see how one could calculate an overall atomic mass with only one isotope is known. An isotope of 186.956 with abundance of 62.6% isn't enough information. We're not told anything about the other isotopes: are they larger, smaller, and at what percentage. If one has an amu of 204.956 at 37.4%, the overall atomic mass would be quite different than if it had an atomic mass of 182.956 at 37.4%. More infornmation is required.

In a free body diagram of all of the forces acting on the book, the force which would keep the book from sliding down the wall is; Choice A: Force of hand.
In modern mechanics, it is noteworthy to know that the normal force, F(n) is the component of a contact force which is perpendicular to the surface that an object contacts.In this instance, the surface which the object contacts is the wall.
It has however been stated within the question that;
A book is held against a wall by applying a force perpendicular to the surface of the book.In conclusion, the force which keeps the book from sliding down the wall is the force of the hand which is perpendicular to the object's surface of contact.

What does it mean to say that a wave is cyclic, or periodic, disturbance?
Answer:
Wave is a disturbance or energy that propagate through medium from one point to other point
So basically it is a flowing energy that flows into the medium and hence medium particles start oscillating about their mean position to and fro.
This motion of medium particles or this to and fro motion is about their mean position and this will always be cyclic or periodic motion
This means the disturbance or energy continuously flow through the medium such that it will change the position of medium particle and this will be cyclic in order
For an example
y(x,t) = Asin(kx - ωt + φ)
So here above equation of wave is a travelling wave in which displacement of medium particle from its mean position is given by "y"
Now we can see that this disturbance depends upon the sine function and it will repeat its same position after every 2 pi time interval as it is cyclic function for this value
Due to this phenomenon of repetition of its same position we can say that it is disturbance of wave is cyclic.
Explanation:
as the temperature of a gas sample at constant pressure increases, the volume of the gas will _____ and there will be _____ gas particles in the same space. the density of a gas at constant pressure therefore _____ as the temperature increases.
Answer:
Increase
Less/low number
Lessen
Explanation:
Increase > Increase in temperature cause increase in volume.
Less/low number > As volume increases the number of particles to be adjusted in the same space will be lesser than before.
Lessen> At constant pressure as increase in temperature cause increase in volume so the density will lessen due to increase in volume. Density equation is given below.
Density = mass /volume
If volume increases density will get lowered.
