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 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.

Answer:

94448421.2201

Explanation:

multiply the value in kilometers by the conversion factor '0.62137119223684'.

So, 152000 kilometers = 152000 × 0.62137119223684 = 94448.42122 miles.

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.

Explanation:

other answer is wrong

An electrolytic cell is a cell with a spontaneous redox reaction (option B).

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:

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:

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.
