Why magnesium starts floating when it reacts with water?
When magnesium reacts with water, it produces hydrogen gas. The bubbles of hydrogen gas attach to the surface of the magnesium, reducing its density. This decrease in density causes the magnesium to float on the surface of the water.
What is result if a piece of magnesium ribbon burn and place the white ash in 5ml of water in a test tube with a red litmus paper?
The result would be that the white ash of magnesium ribbon reacts with water to form magnesium hydroxide, which will turn the red litmus paper blue due to the basic nature of the resulting solution.
What is the reaction mechanism for magnesium ribbon and water?
Very slow reactionMagnesium will react with an acidic solution, (to form H2 gas) at a faster rate than with neutral water, but there is a reaction with water, it is just so slow that only a few bubbles of H2 gas will appear on the surface of the magnesium after around 5 minutes. To increase the rate of the reaction with water, react red hot magnesium with water in the form of steam.See the Web Links to the left for more information about the activity series.
How do you store magnesium ribbon to stop it from turning into magnesium oxide?
usually at school we store it in oil but ts a non flamable oil as it reacts with the oxygen in the air causing the chemical reaction changing it to magnesium hydroxide so you will need to keep in a clear container in oil or just in a container that is air tight and never store it in water as it has a high raction and burns in water
Is magnesium oxide aqueous?
No. Magnesium oxide is not soluble in water. On contact with water it will form magnesium hydroxide.
What is produce when adding burnt Mg ribbon to water?
The burned magnesium ribbon is primarily magnesium oxide, which reacts with water to form magnesium hydroxide according to the equation MgO + H2O => Mg(OH)2.
What happen to nitric acid after magnesium ribbon was placed?
When magnesium ribbon is placed in nitric acid, a chemical reaction occurs where magnesium reacts with the nitric acid to form magnesium nitrate, water, and nitric oxide gas. The magnesium ribbon dissolves and bubbles form as the gas is produced.
What gas is produced by mixing calcium and water and Magnesium ribbon and water?
Hydrogen gas is produced.
What gas is formed when magnesium ribbon and sulfuric acid react?
hydrogen gasmagnesium + sulfuric acid → magnesium sulfate + hydrogen

What changes considered as oxidation reduction reaction burning of magnesium ribbon or electrolysis of water?
both reactions are redox reactions
How can you collect hydrogen coming from a chemical reaction of magnesium ribbon and hydrochloric acid?
First of all, place bits of the magnesium into a test tube. Then pour the acid into the tube, in the meantime locking the tube with a balloon. Tighten it up and theres your stored hydrogen :)

How can you predict whether it will sink or float in the water?
if it starts to go to the bottom that means its sinking and if it stays on the top that means its floating in the water
What colour does magnesium turn added with water and universal indicator?
When magnesium is added to water with universal indicator, the indicator may initially turn blue (indicating a basic solution due to the formation of magnesium hydroxide) before turning back to its original color as the magnesium metal reacts with water to form magnesium hydroxide and hydrogen gas.
