Electrolytic cells use electric currents to drive a non-spontaneous reaction forward. This is also used in electroplating which involves the movement of metal cations to the surface of another metal. Water can also undergo electrochemical reactions by splitting it into its gaseous components, hydrogen and oxygen.
The IUPAC name of a carboxylic acid is derived from that of the longest carbon chain that contains the carboxyl group by dropping the final -e from the name of the parent alkane and adding the suffix -oic followed by the word “acid.” The chain is numbered beginning with the carbon of the carboxyl group.
Answer:
4.8× 10²³ atoms
Explanation:
Given data:
Number of moles of San element = 0.796 mol
Number of atoms present = ?
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
0.796 mol × 6.022 × 10²³ atoms / 1mol
4.8× 10²³ atoms
Answer:
Tyrel is learning about a certain kind of metal used to make satellites. He learns that infrared light is absorbed by the metal. X-ray light is transmitted through the metal. ... Yes, light can cause the metal to get warm because light carries energy.
