Potassium is a chemical element that ignites when it comes into contact with water. When potassium reacts with water, it produces potassium hydroxide and hydrogen gas. This reaction is highly exothermic, meaning it releases a significant amount of heat energy, leading to the ignition of the hydrogen gas. Potassium's reactivity with water is a well-known demonstration of alkali metals' properties in chemistry.
Yea it is a chemical change. The Sodium reacts with water in a chemical reaction in which the sodium displaces the hydrogen in the water, creating sodium oxide and hydrogen gas. The heat from the reaction ignites the hydrogen, which creates the explosion.
Yes, the match head igniting when struck is a chemical property. It involves the chemical reaction between the match head and the striking surface that produces heat, leading to ignition.
Silane. It is similar to methane, CH4, and ignites on contact with air.
Yes, white phosphorus igniting is a physical change because it involves a change in the physical state of the substance (from solid to gas) without altering its chemical composition.
When a hot air balloon flies, the burner at the base of the balloon ignites propane to produce a chemical reaction that converts the propane into carbon dioxide and water vapor. This reaction releases heat, which warms the air inside the balloon, causing it to rise and lift the balloon.
i am asking the same quesion it is on my chemistry homework and i dont know the answer!!
chemical
Photophor is the trade name for the chemical "Calcium Phosphide".On contact with acids or water, Calcium Phosphide,ignites spontan.This chemical is used for incendiary bombs and fireworks.
Yea it is a chemical change. The Sodium reacts with water in a chemical reaction in which the sodium displaces the hydrogen in the water, creating sodium oxide and hydrogen gas. The heat from the reaction ignites the hydrogen, which creates the explosion.
The potassium reacts with water to produce potassium hydroxide, hydrogen gas, and large amounts of heat. The heat ignites the hydrogen which in turn ignites the potassium.
It is an example of a chemical reaction
Carbon dioxide (CO2) and water (H2O)
Yes, the match head igniting when struck is a chemical property. It involves the chemical reaction between the match head and the striking surface that produces heat, leading to ignition.
it grabs electrons from hydrogen and forms H2 which ignites to explode'
When a spark ignites the mixture of gas and fuel in a four-stroke engine, stored chemical energy is converted to thermal energy, which causes the gas and fuel mixture to burn and expand rapidly, generating mechanical energy that powers the engine.
Silane. It is similar to methane, CH4, and ignites on contact with air.
Yes, white phosphorus igniting is a physical change because it involves a change in the physical state of the substance (from solid to gas) without altering its chemical composition.
