All six members of the alkali metals group react violently when exposed to water. When water touches alkali metals the reaction produces hydrogen gas and a strong alkaline solution, also known as a base. The further down... More »

All alkali metals and most alkaline earth metals react with cold water. The alkali metals are lithium, sodium, potassium, rubidium and cesium. The alkaline earth metals that react with water are magnesium, calcium, stron... More »

A metal hydroxide and hydrogen gas form when a metal reacts with water. The metal hydroxide is a strong base. Reactions between a metal (especially an alkali metal) and water usually produce a violent scene. More »

When metal oxides are put into contact with water, they often, though not always, form metal hydroxides. The reaction depends on the element, the acidity of the metal oxide and on the physical state of the water. More »

Some examples of mixtures include metal alloys containing two or more metals, salt dissolved in water, air containing various gases, sand mixed with tiny rocks and pebbles, and trail mix with different types of nuts and ... More »

Ethanol is soluble in water because the polarity of its hydroxyl group is stronger than the nonpolarity of its two carbon chain. In alcohols with more than five carbons in their chain, the repulsive forces between the no... More »

The most reactive metals react with water to form hydrogen gas and their oxides or hydroxides, and with acids to form their oxides or hydroxides. According to the activity series, the first nine metals are highly reactiv... More »
