If you put Magnesium in boiling water, bubbles of Hydrogen are released. Magnesium burns in steam.
More specifically:
Mg(s)+H2O(g) --> Mg(OH)2(s)+H2 (g)
The metals Lithium, calcium, strontium, barium, and, to a limited degree, magnesium produce bubbles of hydrogen gas in water.
SOME metals react with water, releasing hydrogen.
Sodium!!
Answer a. Pure Water is not a mixture - it is a compound. Seawater is a mixture of water and salts, air is a mixture of gases and brass is a mixture (an alloy) of copper and zinc metals.
That is called an alloy.
Distillation of water (resulting in distilled water) is the best way or purifying water. Since the contaminants in water (ions, metals, microbes) are generally larger than water molecules, when water is evaporated, the contaminants are left behind. The evaporated water can then be condensed as pure water.
Mixture. An alloy is a mixture of metals.
Five metals found pure in nature are:copperGoldPlatinumSilver (rarely)Titanium (rarely)There are 93 elemental metals of which platinum, gold, silver, copper, nickel, chromium, iron, aluminum, lead, tungsten, zinc and tin are some of the more commonly known.
Yes. The reaction creates copper sulfate, water, and carbon dioxide gas, which escapes as fizz.
Alkali metals exist only as salts.
yes(:
because u have to with some metals make a mixs ture so there
Carbon dioxide gas puts the fizz in soda water.

Preparation of very pure metals.
is soluble in water and will fizz when hydrochloric acid is added
Alkali metals are not found as pure elements in nature.
Regular water from the tap does not fizz because it is not carbonated. You can purchase carbonated water from the grocery store, which fizzes like soda.
Metals have metallic bonds.
They are actually called the alkali metals. They are called the alkali metals because many of the compounds they form are bases (alkaline) and in pure form they will react with water to produce strong bases.
