Which are base units used in the metric system? Check all that apply. quarts liters grams degrees Fahrenheit degrees Celsius pin

slega [8]

Answer:

The correct answer is liters , grams, degrees Celsius

Explanation:

The metric system is called also international system of units with this short symbols (SI) , It consists of many base units which can measure any physical amount or quantity .example for this bas units the Liters to measure volume, the kilogram and gram to measure the mass , Celsius degrees to measure the temperature using thermometers , also Ampire for measuring the current of the electricity and the second in measuring the time

but quarts , degrees fahrenheit and pints are parts of the imperial system

1) Compounds:

a) Chemically combined.

b) Components change properties.

c) Fixed proportions.

2) Mixtures:

a) Physically combined.

b) Components retain properties.

c) Variable proportions.

3) Both:

a) Made of elements.

b) 2 or more components.

A compound is a pure substance because its molecule cannot be broken down into simpler particles by physical means. For example water (H₂O) is a chemical compound made of two elements (hydrogen and oxygen).

In chemical change new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.

There are no chemical bonds between substances in the mixture.,For example, mixture is solution of water and alcohol.

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

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
