Among many, Sodium. Potassium, even more so.

An alkali metal which reacts with water vigorously with water and sends sparks flying?
Potassium
What is the name of the white colored substance which reacts vigorously with water?
Calcium hydroxide, traditionally called slaked lime is one.
Does calcium tarnish?
Yes. Calcium is very reactive and tarnishes in minutes, if not seconds and if left out will corrode away. It will reacts vigorously with water and will quickly be consumed.
Is prosphorus metal or non metal?
Phosphorous (P, #15) is a non-metal. It reacts vigorously with oxygen, which is why it is used for matchheads.
Does water react with alkali metals vigorously?
Yes
What does lithium react with?
Lithium reacts vigorously (but not violently) with water.
An alkali metal which reacts with water vigorously with water and sends sparks flying?
Potassium
How does calcium react in water?
Yes. Calcium reacts vigorously with water producing hydrogen and calcium hydroxide.
Why Li react slowly with water?
Li does NOT react slowly with water. It reacts vigorously to produce LiOH + H2 gas.
What group on the periodic table reacts violenty with water?
Group one elements react vigorously with water.They even react when exposed to air.For example lithium reacts violently with water.
What is the type of reaction called when quick lime reacts vigorously with water releasing a large amount of heat?
Exothermic
What is the equation of ammonium bromide plus water?
Al2Br6 reacts vigorously with water with evolution of HBr and formation of Al-OH-Br species.
What is the name of the white colored substance which reacts vigorously with water?
Calcium hydroxide, traditionally called slaked lime is one.
A metal which reacts least vigorously with water 1.Zn 2.Mg 3.Fe 4.Al?
Zn
What metal reacts more vigorously than calcium?
sodium
What are the observations when potassium reacts with water?
Potassium reacts vigorously with water, as it is one of the most reactive alkali metals. When it does, it floats on top of the water, and burns a lilac flame. It also may explode. Fizzing and bubbling will also be seen as hydrogen gas is produced. The potassium reacts with the water to become a hydroxide (potassium hydroxide)
Whow does potassium react in water?
When Potassium is put in water, it reacts vigorously. It sends out a purple flame and it makes a small explosion. You can also smell the smell of burnt fumes.
