Mercury oxide is heated to form oxygen?
A chemical reaction happens when mercury is heated and reacts with oxygen. This reaction results in the creation of mercuric oxide, an orange or red compound.
What is the word equation for solid mercury two oxide breads down when heated forming the elements mercury and oxygen?
Mercury+Oxygen----> Mercury Oxide
What is formed when limestone is heated?
When heated, limestone forms two different things. It forms both calcium oxide and carbon dioxide. This occurs because limestone is made up of calcium carbonate.
What happens when Hg oxide is heated?
When mercuric oxide is strongly heated in a hard glass tube, it decomposes, globules of mercury collect in the cooler part of the tube and oxygen gas is evolved. It may be collected over mercury in a pure and dry state.
What is formed when magnesium is heated?
The solid formed is magnesium oxide.The gas formed is carbon dioxide.

Mercury+Oxygen----> Mercury Oxide
What forms a black oxide when it is heated?
Copper
What metal forms a black oxide when heated?
copperCopper (cupric) oxide is produced. Therefore, copper is the metal that produces a black oxide when heated.
What would be the combined mass of the released oxygen and mercury if 20g of mercury oxide were heated?
10

What element combines with Magnesium when heated in a crucible?
oxygen...it forms magnesium oxide
What happens to the mass when magnesium is heated in air?
When magnesium is heated in air, it forms magnesium oxide and so the total mass increases.
Is sodium metal that forms an oxide when heated with oxygen a chem or phy change?
Chemical change
When solid calcium carbonate is heated what is form?
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
