You get a grey powder because magnesium is higher up in the reactivity series than Copper - (magnesium is more reactive than copper) therefore when you heat it up there is a displacement reaction. That grey powder is actully magnesium oxide and copper e.g Copper oxide + magnesium = magnesium oxide and copper.
What else can I help you with?
What is the color of copper oxide?
There are two copper oxides, differing in color:if it is black powder, then it is copper(II) oxide CuO (cupric, more common, as in the mineral 'tenoriet')if it is red powder, then it is copper(I) oxide Cu2O (cuprous oxide, as in mineral the 'cupriet' and it occurs in 'Benedict's test' on reducing sugars)
What happens when magnisium burns?
When magnesium burns, it reacts with oxygen in the air to form magnesium oxide and produces a bright white light. This is a highly exothermic reaction, releasing a large amount of heat and energy. The resulting magnesium oxide residue is a white powder.
How do you know that magnesium is the more metallic element in the compound magnesium oxide MgO?
Magnesium is an element, a metal. It is silvery grey in colour and has lustre.whereas Magnesium Oxide is a compound made from reaction of magnesium and oxygen. It is a powdery substance and is white in colour
When an oxidised copper coin is placed in a beaker of hydrochloric acid why does it turn shiny?
When a copper coin is oxidized, it forms a dull layer of copper oxide on the surface. When placed in hydrochloric acid, the acid reacts with the copper oxide layer to form copper chloride, which is soluble in the acid. This process removes the oxide layer, revealing the shiny copper surface underneath.
What is the natural color of magnesium?
The natural color of magnesium is a shiny grey-white or silvery-white.
What is the color of copper oxide?
There are two copper oxides, differing in color:if it is black powder, then it is copper(II) oxide CuO (cupric, more common, as in the mineral 'tenoriet')if it is red powder, then it is copper(I) oxide Cu2O (cuprous oxide, as in mineral the 'cupriet' and it occurs in 'Benedict's test' on reducing sugars)
Is copperII oxide an solid or an aqueous solution?
Copper(II) oxide is a solid. It is a black powder that is insoluble in water and often used as a pigment or catalyst.

Is magnesium shiny and does it conduct heat and electricity?
Magnesium would only be shiny in a freshly cut surface. It quickly oxidizes with a film of protective oxide rapidly forming. In this condition it would look grey. It does conduct both heat and electricity.
When an oxidised copper coin is placed in a beaker of hydrochloric acid why does it turn shiny?

When placed in hydrochloric acid, the acid reacts with the copper oxide layer to form copper chloride, which is soluble in the acid. This process removes the oxide layer, revealing the shiny copper surface underneath.
Describe what happens to magnesium when it is burnt?
When it reaches the flame, it ignites and burns with an extremely bright white light. It's so bright it could damage your eyes, so you should not look directly at it. The magnesium metal combines with oxygen from the air to form a white ash called magnesium oxide. This is a redox reaction. Magnesium atoms lose electrons and oxygen atoms gain them, resulting in an ionic compound, Mg2+O2- (where the numbers and charges should be superscripts). There is also a small amount of reaction with the nitrogen of the air, forming magnesium nitride.
What is the natural color of magnesium?
The natural color of magnesium is a shiny grey-white or silvery-white.
What happens and what is produced when calcium is heated in air?
When calcium is heated in air, it reacts with oxygen to form calcium oxide (CaO) and calcium nitride (Ca3N2). The calcium oxide is a white solid, while the calcium nitride is a grey powder. Heat is also produced during the reaction.

What is a wüstite?
A wüstite is a grey mineral form of iron(II) oxide with a greenish tint.
