Why does aluminium not react with water under ordinary conditions? To me, it seems like a metal would need to be more reactive to be able to react with hot water since HCl is a very strong acid and so should theoretically be able to react with more metals, but I am not so sure. In general, Group 1 (IA or alkali) metals and Group 2 (IIA or alkaline earth) metals are more active than transition metals. For example, the reaction between potassium and water yields potassium hydroxide and H 2 gas, as described by the chemical equation provided below. Strontium and barium have reactivities similar to that of lithium. Additionally, beryllium has a resistant outer oxide layer that lowers its reactivity at lower temperatures.

Reaction of lanthanum with water. Reaction of Iron with water: Reaction of iron with cold water is very slow and come into notice after a long time. The reactivity of the metal determines which reactions the metal participates in. A more active metal will react more readily with water than a less active metal. Which of the following oxide (s) of iron would be obtained on the prolonged reaction of iron with steam? hydroxide and hydrogen gas. 2. [B]. Rubidium is denser than water and so sinks.

Which of the following metals react with steam but not with cold water, to give hydrogen gas? The reason for using cold water rather than hot water for the reactions of alkali metals is that alkali metals are already reactive enough at room temperature. 2)Magnesium is less reactive metal so it react slowly with cold water,it reacts rapidly only with hot boiling water. It reacts violently and immediately, with everything spitting out of the container again. Write any three observations you would make when such a metal is dropped into water. 1)Sodium is a very reactive metal,therefore sodium metal react violently even with cold water. Name two metals which react violently with cold water. If the gas evolved burns with a 'pop' sound, it indicates that it is hydrogen gas. Name Two metals which give hydrogen with cold water. Rubidium hydroxide solution and hydrogen are formed. and hydrogen gas Magnesium does not react with cold water but with hot water to form magnesium ! Soon the metal catches fire and starts burning.

Name two metals which react violently with cold water. Calcium, Strontium, and Barium These metals react with cold water with increasing vigor to give the metal hydroxide and hydrogen. Potassium reacts violently with cold water . This is because enough heat is given off during the exothermic reaction to ignite the H 2 (g). Sodium reacts vigorously with cold water forming sodium hydroxide and hydrogen gas. Galvanization or galvanizing (also spelled galvanisation or galvanising) is the process of applying a protective zinc coating to steel or iron, to prevent rusting.The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten hot zinc. Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if metal is heated to red heat. which metal reacts violently with cold water than does potassium? Potassium reacts violently with cold water . Metal starts reacting with water causing little explosions. The alkaline earth metals (Be, Mg, Ca, Sr, Ba, and Ra) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity in the higher periods. Iron forms rust (iron oxide) when reacts with moisture present in atmosphere. These metals react with cold water with increasing vigor to give the metal hydroxide and hydrogen. 1.
