Question

which metals reacts with water at high temperature answer the following​

Answer 1

Answer:

Water-reactive substances[1] are those that spontaneously undergo a chemical reaction with water, as they are highly reducing in nature.[2] Notable examples include alkali metals, sodium through caesium, and alkaline earth metals, magnesium through barium.

Some water-reactive substances are also pyrophoric, like organometallics and sulfuric acid, and should be kept away from moisture. The use of acid-resistant gloves and face shield are required and should be handled in fume hoods.[3]

Water-reactive substances are classified as R2 under the UN classification system and as Hazard 4.3 by the United States Department of Transportation.

All chemicals that react vigorously with water or liberate toxic gas when in contact with water are recognized for their hazardous nature in the 'Approved Supply List,'[4] or the list of substances covered by the international legislation on major hazards[5] many of which are commonly used in manufacturing processes.

Answer 2

Alkali metals are reacts with water at high temperature.  

Explanation:

• Alkali metals and alkaline earth metals react with water and its produce hydrogen.
• The alkali metals comprise Group 1 of the periodic table, and include lithium, sodium, potassium, rubidium, cesium, and francium.
• The alkali metals are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1.
• All the alkali metals react with water, with the heavier alkali metals reacting more vigorously than the lighter ones.
