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

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.

An atom has 7 protons, 8 electrons, and 7 neutrons. What is the charge of the
atom and what type of ion is it?
Answers
Answer: An atom containing 7 protons, 8 neutrons, and 7 electrons is charge-neutral.
Explanation:
An atom is composed of protons (positively charged), neutrons (no charge) and electrons (negatively charged). The excess or defect of electrons in relation to protons determines the charge of an atom.
The atom described is an anion with -1 charge as it has one extra electron than protons.
What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answers
The element belongs to group 17 of the periodic table.
In the periodic table, elements are arranged in groups depending on their properties. Usually, elements whose atoms have the same number of valence electrons are placed in the same group.
All the elements in group 17 have seven electrons on their outermost shell. Since an ionization energies of the electrons on the valence shell of an atom are always close together, the ionization energies of the seven electrons as shown indicate that they must be on the same shell.
Hence, the new element must be a member of group 17 of the periodic table.

The density of a liquid is 6.0g/cm3 , when it fills a container of volume 300cubic centimeters . What is the mass of the liquid in the container?
Answers
Answer:
1800g
Explanation:
b/c d=m/v
m=dv
m=300×6=1800g
The mass of the liquid in the container is equal to 1800 g.
What is the density?The density of an object can be described as the mass per unit volume of the object. The average density of any substance equals the total mass of the substance divided by its total volume.
The mathematical formula of the density can be expressed as follows:
The density of material = Mass/Volume
Mass = density × Volume
The S.I. unit of the density of any substance is Kg/m³ and it is an intrinsic property. If the size of the substance increases, the mass increases as well but the density of the substance will stay constant.
Give, the density of the liquid, d = 6.0 g/cm³
The volume of the container, V = 300 cm³
The mass of the liquid = 6 ×300 = 1800 g
Therefore, the mass of the liquid is equal to 1800 g.
