Reactions of metal with oxygen Flashcards
How does magnesium react with steam?
Magnesium reacts with steam to form magnesium oxide and hydrogen gas.
What is needed for magnesium to react with steam?
Heat is required to start the reaction.
What are the observations when magnesium reacts with steam?
A bright white flame and white powder (MgO) left behind.
Why doesn’t magnesium react with cold water?
Magnesium is less reactive than calcium, sodium, and potassium.
What is the word equation for magnesium reacting with steam what does the g after water indicate?
Magnesium + Water(g) → Magnesium Oxide + Hydrogen, where the g after water indicates water in the form of a gas, in this case steam.
Why does magnesium react with steam but not cold water?
The energy provided by steam is enough to make it react.
What is the difference between steam and water vapour?
Steam is made by boiling water and is very hot, whereas water vapour is made up of water particles in the air, which are at lower temperatures.
What is an example of a metal that does not react at all with water?
Some metals, such as gold, do not react with water at all.
