Describe A Test To Distinguish Between Calcium Chloride

Calcium and sodium are 3rd and 4th from the left respectively. (Image from BBC GCSE Chemistry) There are a couple of simple tests you could do to identify the anion. If you dissolve a sample of each in water sodium oxide is strongly alkaline to pH paper (10-14) whereas calcium chloride will be neutral.

99.99% Oxide powder, Iron Oxide (Fe2O3), Zinc Oxide (ZnO

Oxide powder and metal oxides are widely used in our daily life. Quicklime is a commonly used desiccant and can also be used for disinfection; iron oxide (Fe2O3), commonly known as iron red, can be used as a red pigment; some of the alysts used in industrial processes are also metal oxides.

Thermite Reaction: aluminum reacts with iron(III) oxide

The reaction of iron (III) oxide and aluminum is initiated by heat released from a small amount "starter mixture". This reaction is an oxidation-reduction reaction, a single replacement reaction, producing great quantities of heat (flame and sparks) and a stream of molten iron and aluminum oxide which pours out of a hole in the bottom of the pot into sand.

Thermite - Sciencemadness Wiki

Thermite is an energetic composition consisting of a metal powder and metal oxide.Thermites are a special type of single replacment reactions that do not take place in aqueous solution. They are capable of producing extreme heat, enough to melt or boil other metals. The products of this reaction are the oxide of the metal powder, and pure metal produced from the oxide.

The Reaction Of Magnesium With Oxygen | Reactions Of

When a metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is: metal + oxygen → metal oxide. Some metals will react with oxygen when they burn. These reactions are called coustion reactions. Two examples of coustion reactions are: Iron reacts with oxygen to form iron oxide: 4 Fe + 3 O 2 → 2 Fe 2 O 3
