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.

What else can I help you with?
Formula of magnesium ribbon?
Science Sucks!!!!!!!! i know and im Liz i have to do a project due 2morrow and i havent even started
What happens when magnesium ribbon is burnt in air?
Magnesium is an extremely reactive metal. When stored, it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper for removing this layer so that the underlying metal can be exposed to air.
Products of Mg ribbon ASH plus HCl?
When magnesium ribbon reacts with hydrochloric acid (HCl), magnesium chloride forms along with hydrogen gas being produced as a byproduct. The chemical equation for this reaction is: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)
Mg ribbon ash with hcl what is the product?
Mg(s) + 2HCl(aq) ---> MgCl2(aq) + H2(g)
How does the Mg ribbon differ from the Magnesium Oxide formed after burning the metal?
2Mg^2+ + O2 -- > 2MgO This is the chemical reaction occurring when burning magnesium. When burning the metal in air, which is slightly less than 20% O2, there is less O2 for the Mg to react with than there would be in a pure O2 environment. In the high O2 concentration environment the Mg doesn't have to "wait" for more O2 to diffuse into the area before the reaction can occur. In the case of burning Mg in air, the O2 conc. is much lower, and therefore depleted faster, and in turn must "wait" for more O2 to diffuse into the area. The reason it seems to burn hotter and bright is because all the energy being release from the combustion is able to happen much faster in the pure O2 environment. Provided you were burning the same mass of Mg, the same TOTAL amount of energy is released in both reactions, the pure O2 environment just allows it to happen in a shorter time frame. Energy released reacting (enthlapy of combustion)1 mol of Mg = -1200 kJ/mol regardless of the O2 saturation in the environment. Reacting it in a pure oxygen environment just allows the reaction to happen faster.
What happens when mg ribbon is mixed with calcium carbonate?
Any reaction occur.
Mg ribbon continuous to burn in presence of CO 2.why?
When magnesium ribbon burns in the presence of CO2, it forms magnesium oxide and carbon. The reaction is exothermic, releasing heat to sustain the burning of the magnesium ribbon. The CO2 supplies oxygen to support combustion.
What is the formula of Magnessium ribbon?
The formula of magnesium ribbon is simply Mg, representing a single magnesium atom.

What happens when igniting Mg ribbon?
It gives off a bright white light (glowing manner) that shouldn't be looked at with the naked eye.
What happens when you burn magnsium in oxygen?
Oxydation of magnesium: 2 Mg + O2 = 2 MgO
What happens Mg is burnt in air?
The product is magnesium oxide MgO.
Can metal burn like the match?
like Mg is a meta and it burn in the presence of N2. Na is also a metal which is so reactive and it explode in the contact of water and air.

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.
Mg ribbon ash with hcl what is the product?
Mg(s) + 2HCl(aq) ---> MgCl2(aq) + H2(g)
