Yes , it is true.
Sodium metal can react violently with water to produce sodium hydroxide and hydrogen gas, which can cause burns if it comes in contact with skin.
Some of these metals are: Calcium, Magnesium, Sulfur, Sodium, Potassium, ...
Li (Lithium), Na (Sodium), K (potassium). They are highly reactive - they react violently with water and also react with oxygen.
Three metals that react with cold water are sodium, potassium, and lithium. These alkali metals react vigorously with water, producing hydrogen gas and corresponding hydroxides. Sodium reacts to form sodium hydroxide, while potassium reacts more violently, leading to the production of potassium hydroxide. Lithium reacts more slowly compared to the other two but still produces lithium hydroxide and hydrogen when in contact with cold water.
Yes, and violently so.
Potassium (K) will react faster with acids than sodium (Na) because potassium is more reactive than sodium due to its lower ionization energy. This makes potassium more likely to displace hydrogen in acids and react more vigorously.
Reactive metals like sodium, potassium, and magnesium react quickly with water to produce hydrogen gas. Strong acids like hydrochloric acid and sulfuric acid also react quickly with metals to produce metal salts and hydrogen gas.
Two elements that can react violently are sodium (Na) and chlorine (Cl) to form sodium chloride (table salt). Additionally, potassium (K) and water can also react violently due to the release of hydrogen gas.
Yes, the reaction between sodium/potassium and water is a chemical change. This reaction produces hydrogen gas and hydroxide ions, resulting in the formation of a new substance with different properties than the reactants.
Sodium metal can react violently with water to produce sodium hydroxide and hydrogen gas, which can cause burns if it comes in contact with skin.
Yes.
Yes, cesium is expected to react violently with water. This is because cesium belongs to the same group (alkali metals) in the periodic table as lithium, sodium, and potassium, which are known to react violently with water due to their highly reactive nature and tendency to form alkaline hydroxides and release hydrogen gas.
Metals such as sodium, potassium, and lithium can react violently with acids. These reactions can produce heat, hydrogen gas, and cause the acid to splash. Special precautions should be taken when working with these reactive metals to prevent accidents.
Some of these metals are: Calcium, Magnesium, Sulfur, Sodium, Potassium, ...

Both potassium and sodium react vigorously with cold water to form metal hydroxides and hydrogen gas. However, the reaction of potassium is more violent and produces a louder explosion due to its higher reactivity compared to sodium. Potassium reacts faster and more violently than sodium in water.
Metals such as magnesium, zinc, and iron will react more violently than aluminum with hydrochloric acid. This is because these metals are higher in the reactivity series and will displace hydrogen gas more readily from the acid.
