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 »

While exploring what happens when metals come in contact with acids, it is apparent that most, but not all, have some sort of reaction, usually forming hydrogen gas. The result is the production of salts. More »

The solubility of elemental calcium in water is unassessable because calcium reacts with liquid water to produce calcium hydroxide in a hydrolysis reaction. The reaction produces hydrogen gas and calcium hydroxide as byp... More »

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 »

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 »

Hot water freezes faster compared to cold water, due to the intermolecular bonding between water molecules, based on a study conducted by the Nanyang Technological University in Singapore. This phenomenon is known as the... More » Science Physics Thermodynamics

Brass is an alloy that is a mixture of the metals zinc and copper. Using brass makes sense for many manufacturers since it is durable and easily transformed into objects. More »
