What happen when mercuric oxide is heated?
What happen when mercuric oxide is heated?
When mercuric oxide is heated, it decomposes to give mercury and oxygen.
What type of reaction is HgO → Hg O2?
decomposition reaction
Explanation: Reddish Mercury(II)oxide solid is decomposed (broken down) upon heating into silver liquid mercury and colourless oxygen gas. This is a decomposition reaction.

Which gas is released when mercuric oxide is reduced to mercury on heating?
oxygen gas
The simplest kind of decomposition reaction is when a binary compound decomposes into its elements. Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas.
What happens when mixture of cuprous oxide and cuprous sulphide is heated?
Mixture of cuprous oxide and cuprous sulphide is heated to form copper metal. Copper metal is obtained when cuprous oxide is heated with cuprous sulphide. Sulphur dioxide gas is released as by-product with a very unusual smell.
Is 2HgO → 2hg o2 a balanced equation?
O is a balanced element because there is the same number of atoms of O in each side of the equation. All elements have the same number of atoms in each side of the equation, which means that the law of conservation of mass is satisfied and the chemical equation is balanced.

What happens when write balanced chemical equation?
According to the law of conservation of mass, when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants. A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.
