Answer: Hope this helps you out!

An ammeter is an instrument that measures electric currents in amperes. It measures a current in a circuit.

A voltmeter is used for measuring voltage in volts. It measures the electrical potential between two points within a circuit.

Describe the trends in electron configuration in the periodic table by selecting the terms from the drop-down menus.

Fittoniya [83]

Increases

Stays the same

s-orbitals

d-orbitals

p-orbitals

Explanation:

The trend in the electronic configuration on the periodic table follows a definite pattern because the arrangement of elements on the table is based on the periodic law.

The periodic law states that "The properties of elements are a function of their atomic number".

Elements in the same horizontal period have increasing number of valence electrons.
The number of valence electrons stays the same down a group.
Groups 1 and 2 are known as the s-block and electrons are added to the s-orbitals for them.
Groups 3 to 12 is the transition block and electrons the valence d-orbital.
Groups 3 through 18 is the p-block where the valence shell is the p-orbital.

Two voltaic cells are to be joined so that one will run the other as an electrolytic cell. In the first cell, one half-cell has

vladimir1956 [14]

Au/Cr cell will run as a voltaic cell and Co/Zn cell will run as an electrolytic cell.

<h3>What is an electrolytic cell?</h3>

An electrolytic cell that uses electrical energy to enable a non-spontaneous redox reaction is known as an electrolytic cell.

Certain chemicals can be electrolyzed using electrolytic cells, which are electrochemical cells.

For example, water can be electrolyzed to create gaseous oxygen and gaseous hydrogen with the use of an electrolytic cell.

The following are the three essential parts of electrolytic cells:

Cathode (which is negatively charged for electrolytic cells)

Anode (which is positively charged for electrolytic cells)

Electrolyte

The reactions for each half cell is given by

$Au^{3+}(aq) + 3e^- \rightleftharpoons Au(s)$ ; E° = 1.50 V

$Cr^{3+}(aq) + 3e^- \rightleftharpoons Cr(s)$ ; E° = –0.74 V

$Co^{2+}(aq) + 2e^- \rightleftharpoons Co(s)$ ; E° = –0.28 V

$Zn^{2+}(aq) + 2e^- \rightleftharpoons Zn(s)$ ; E° = –0.76 V

When the Au/Cr cell will run as a voltaic cell and Co/Zn cell will run as an electrolytic cell, the a difference in the voltages is produced

$E^o_{series} = E^o_{Au/Cr} - E^o_{Co/Zn}$ = 2.24 V – 0.48 V = 1.76 V

Most of the chemicals included in your introductory chemistry lab kit can be discarded down a drain with copious amounts of wate

il63 [147K]

Answer:

Explanation:

To neutralize a chemical to a pH of 7 before discarding, one would require a significant amount of acids or bases. Our best guess is that the solution in itself is either an acid or a base. Neutralization with the right amount of a proper reagent can bring the pH of the solution to a neutral 7.

If the solution has a pH originally greater than 7, add a corresponding amount of acid to it. This will reduce the concentration and bring it to a neutral point. Provided one is dealing with a solution of pH less than 7, simply add a base to to bring the solution to neutrality.
