What do you see when you burn magnesium ribbon?
it turn white as ash
Products of Mg ribbon ASH plus HCl?
Mg ribbon ash indicates you heated magnesium ribbon in a crucible and had it render the oxide. MgO MgO + 2HCl --> MgCl2 + H2O
White ash obtained by burning magnesium ribbon?
the white ash is the chemial product produced when Mg is reacted with oxide.There the white ash is MgO(magnesuim oxide)
What is the product of the reaction between a magnesium ribbon without ash and hydrochloric acid?
Mg +2HCl >> MgCl2 + H2 A salt and hydrogen gas.
What weighs more magnesium or the white ash?
Magnesium weight more than ash. White ash is magnesium oxide.
What weighs more magnesium or white ash?
Magnesium weight more than ash. White ash is magnesium oxide.
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 red litmus paper will turn blue.
What is the solution of ash of magnesium ribbons?
the answer is acidic
What is the chemical name for white ash?
Magnesium oxide
Why when magnesium ribbon is burnt the ash is heavier?
When Magnesium burns, it is actually combining with oxygen in the air to form a new compound, magnesium oxide. If we were to carefully weigh a piece of magnesium before and after burning it, you would see that its weight increased by about one third. For example, if you start with 100 grams of magnesium, after the burn you would end up with about 130 grams of magnesium oxide. The fact that the magnesium oxide you create by burning is powdery, means that it takes up more space (size or volume) than the solid magnesium did.
When coal is burned the ash weighs less than the coal when magnesium burns the ash weighs more than magnesium?
That is true. Coal is composed mostly of carbon, and when it burns it turns into carbon dioxide, which is a gas. The ash is just a minor residue of the non-carbon part of the coal. Whereas, magnesium when it burns turns into a solid material, magnesium oxide; it gains oxygen from the air and therefore increases in weight.
Magnesium burning in air is an example of this type of chemical change?
The magnesium burns readily in air to produce a white ash which is magnesium oxide. This is due to the "oxidation" of the metal.
