Calculating molar mass and nuer of moles (worked …
The molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance''s molar mass by summing the molar masses of its component atoms. We can then use the calculated molar mass to convert between mass and nuer of moles of the substance.

Ionization Energy of Chemical Elements - Periodic Table
Sodium is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ ion.
What is the difference between a sodium atom and a …
Sodium, an Alkali Metal from Group 1 of the periodic table, is the element with atomic nuer 11. That means it has 11 protons in its nucleus. A neutral atom of sodium will have
How Metals are Made - Today I Found Out
One is sodium—a metal we regularly eat: Sodium is a soft, silvery white metal that commonly bonds with the element chlorine to form sodium chloride, or common salt. Another is astatine, which was discovered in 1940 in a lab, where it was created artificially.
Sodium Bicarbonate Uses - Science Struck
Sodium bicarbonate is a very useful chemical compound having a crystalline salt-like appearance. This compound has revolutionized many production processes, and has also resulted in the effective development of several different consumer products and other substances. In this Buzzle article, we take a look at the different uses of sodium bicarbonate.

Electrolysis of molten sodium chloride gives silvery sodium metal and pale green chlorine gas. This is a simpler electrolysis situation where the ionic compound sodium chloride on melting provides a highly concentrated mixture of positive sodium ions and negative chloride ions.
10 Sodium Hypochlorite Uses in Everyday Life - …
There are several appliions of sodium hypochlorite uses in everyday life. Below are the appliions of this chemical solution. 1. Whitening Agent Whitening agent or also known as bleach for is commonly the solution that contains 4-6% of sodium
Sodium metal that forms at the hode floats up through the molten sodium chloride into a sodium-collecting ring, from which it is periodically drained. The diaphragm that separates the two electrodes is a screen of iron gauze, which prevents the explosive reaction that would occur if the products of the electrolysis reaction came in contact.
