WebApr 8, 2024 · Hint: The metal which reacts with cold water is highly reactive. It is silvery- white and soft metal. It is also an alkali metal. Complete step by step solution: Let’s … Web1 Answer Sorted by: 2 Magnesium is a very active metal- highest activity of all engineering metals. Your question gives you part of the answer. In cold water it forms a decent protective layer. Given greater activation energy- simple as hot water, that layers is simply damaged the oxidation of the magnesium proceeds unimpeded at a greater rate.

How does the temperature of water affect the reactivity of alkali ...

Metal Reactions with water or steam Most reactive: potassium (K) Very vigorous reaction with cold water Second most reactive: sodium (Na) Vigorous reaction with cold water Third most reactive: calcium (Ca) Less vigorous reaction with cold water Least reactive: magnesium (Mg) Slow reaction with cold water, … See more Water-reactive substances are those that spontaneously undergo a chemical reaction with water, as they are highly reducing in nature. Notable examples include alkali metals, lithium through caesium, … See more 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, … See more The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table - they all react vigorously or even explosively with cold water, resulting in the displacement of … See more WebWhen a non-metal reacts with oxygen, it forms an oxide. The nature of the oxide formed depends on the non-metal involved in the reaction. Acidic Nature of Non-Metal Oxides:Non-metals tend to form acidic oxides when they react with oxygen. This is because non-metal oxides react with water to form acids. For example, sulfur dioxide (SO2) is a non-metal … lowe\u0027s payment phone number

WebAliphatic metal alkoxides decompose in water as summarized in this idealized equation: Al(OR) 3 + 3 H 2 O → Al 2 O 3 + 3 ROH. In the transesterification process, metal alkoxides react with esters to bring about an exchange of alkyl groups between metal alkoxide and ester. With the metal alkoxide complex in focus, the result is the same as for ... WebHowever, metals like copper (Cu) and silver (Ag) form oxides that are acidic in nature. Acidic oxides react with water to form acidic solutions. For example, copper oxide (CuO) is an acidic oxide.Conclusion:The nature of the oxide formed when a metal reacts with oxygen depends on the reactivity of the metal. WebReaction of metal with cold water: Alkali metals usually have higher reactivity than other metals. Thus an alkali metal can react vigorously with cold water producing Hydrogen … lowe\u0027s payroll portal
