What is the formula mass for carbon dioxide?

Chemistry
1 answer:
scZoUnD [109]3 years ago
3 0
The molecular mass of the compound CO2 is calculate by simply taking the number of atoms of each element and multiplying it by the molar mass of the element on the periodic table.

C = 1 • 12.0 g/mol
O2 = 2 • 16.0 g/mol = 32.0 g/mol
CO2 = 12.0 + 32.0 = 44.0 g/mol.

The formula mass of CO2 is 44.0 g/mol.

A camcorder has a power rating of 11 watts. If the output voltage from its battery is 8 volts, what current does it use?
Reika [66]

The camcorder uses a current of 1.4 A.

<em>P = VI </em>

<em>I</em> = <em>P</em>/<em>V</em> = 11 W/8 V = 1.4 A

<em>Note</em>: The answer can have only <em>one significant figure</em> because that is all you gave for the voltage. However, I calculated the current to two significant figures.

Which property of an atom's structure was used to organize the periodic table?
VashaNatasha [74]
It is the outermost electrons, for example all the first line has one outer electron and the second has to and so on and so forth. BUT THE TRANSITION METALS FOLLOW A DIFFERENT RULE.

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
