Which metal reacts with water and burns with a lilac flame?
Potassium has a violet color in the flame test.
When an alkali metal reacts with water it produces what?
When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
What alkali metal reacts most slowly with water?
Among the alkali metals, lithium reacts most slowly with water. When lithium comes into contact with water, it forms lithium hydroxide and hydrogen gas. Due to lithium's smaller size and lower reactivity compared to other alkali metals, the reaction occurs at a slower rate.
Why does magnesium react slowly with water?
Magnesium reacts slowly with water because it has a protective oxide layer on its surface that inhibits the reaction. This oxide layer serves as a barrier, preventing water from coming into direct contact with the magnesium metal and slowing down the reaction rate.
When a metal reacts with water what products are made?
When a metal reacts with water, it can produce metal hydroxide and hydrogen gas. The metal hydroxide is a basic compound that dissolves in water to form a basic solution, while the hydrogen gas is released as a byproduct of the reaction.
Which metal burns in air but only react very slowly with water?
Copper burns and reacts in the air to form copper oxide, however i htink it reacts very slowly with water. Hope that helped ;)
What is the metal that reacts slowly with cold water to form a hydroxide?
The metal that reacts slowly with cold water to form a hydroxide is magnesium. When magnesium reacts with water, it forms magnesium hydroxide and hydrogen gas.
What metal reacts in the air but slowly in the water?
copper
What is grey metal that reacts with water?
Zinc is a grey metal that can react with water, although it does so slowly. When zinc reacts with water, it produces zinc hydroxide and hydrogen gas.
A metal oxide reacts with water to produce what?
A metal oxide reacts with water to produce a metal hydroxide.
What is a description of the characteristics of sodium?
Alkali metal, reacts violently with water (spontaneous combustion), silvery white, burns bright yellow/orange.
What metal burns with a white flame?
potassium and sodium react very violently with cold water calcium reacts slowly with cold water Magnesium is not affected by water at room temperature or cold water.Magnesium reacts with water vapor only.
Which metal reacts with water and burns with a lilac flame?
Potassium has a violet color in the flame test.
What metal reacts quickly with water and acid?
Metals that react well with water: Sodium - fizzes Potassium - burns Caesium - explodes Metals that react well with acids: Magnesium
What metal burns readily underwater?
Sodium is a metal that burns readily underwater. When exposed to water, sodium reacts vigorously, releasing hydrogen gas and generating enough heat to ignite the hydrogen, resulting in a bright yellow flame.
When an alkali metal reacts with water it produces what?
When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
What happens when non metal reacting with water?
neutral Depends on the nonmetal. Fluorine reacts differentpy from boron.
