What is the decomposition of hg2o?
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.
Is hg2o soluble in water?
Mercury oxide appears as black or brownish-black powder. Not a true compound but rather an intimate mixture of metallic mercury and mercuric oxide. Insoluble in water and denser than water (density 9.8 g / cm3).
What is hg2o in chemistry?
Mercury(I) oxide, also known as mercurous oxide, is an inorganic metal oxide with the chemical formula Hg2O. It is a brown/black powder, insoluble in water but soluble in nitric acid. It is chemically unstable and converts to mercury(II) oxide and mercury metal.
What is the balanced chemical equation for the decomposition of water?
Combining either half reaction pair yields the same overall decomposition of water into oxygen and hydrogen: Overall reaction: 2 H2O(l) → 2 H2(g) + O2(g) The number of hydrogen molecules produced is thus twice the number of oxygen molecules.
At what temperature does HgO decompose?
HgO decomposes on exposure to light or on heating above 500 °C.

What is the Valency of mercury?
hg has a valency of +1 and +2 in +1 valency it’s called mercurous and in +2 valency its called mercuric!
What is the decomposition equation?
A decomposition reaction occurs when one reactant breaks down into two or more products. It can be represented by the general equation: AB → A + B. In this equation, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction.
What happens when hydrogen fluoride is combined with water?
When hydrogen fluoride is combined with water it is known as hydrofluoric acid, a colorless liquid, which in low concentrations is visually indistinguishable from water. Hydrofluoric acid that is more than 40% hydrogen fluoride fumes in air.
What happens when water is split into oxygen and hydrogen?
Water splitting is the chemical reaction in which water is broken down into oxygen and hydrogen:
How do you balance H2O and H2 + O2?
In order to balance H2O = H2 + O2 you’ll need to be sure to count all of H and O atoms on each side of the chemical equation. Once you know how many of each type of atom you have you can only change the coefficients (the numbers in front of atoms or compounds) in order to balance…
Which is the colorless gas that dissolves in water?
Hydrogen fluoride is a colorless, fuming liquid or gas with a strong, irritating odor. It is usually shipped in steel cylinders as a compressed gas. Hydrogen fluoride readily dissolves in water to form colorless hydrofluoric acid solutions; dilute solutions are visibly indistinguishable from water. Hydrofluoric acid.
