What is the molar mass of liquid mercury?
200.59 g
a) The atomic weight of mercury is 200.59, and so 1 mol Hg weighs 200.59 g.
What is the formula for mercury I oxide?
Hg2OMercury(I) oxide / Formula
What is liquid mercury?
Elemental (Metallic) Mercury Elemental or metallic mercury is a shiny, silver-white metal, historically referred to as quicksilver, and is liquid at room temperature. It is used in older thermometers, fluorescent light bulbs and some electrical switches.
Does mercury react with oxygen?
Mercury does not combine with oxygen to produce mercury(II) oxide, HgO, at a useful rate until heated to the range of 300 to 350 °C (572 to 662 °F). At temperatures of about 400 °C (752 °F) and above, the reaction reverses with the compound decomposing into its elements.
How do you balance Hg +02?
Mercuric oxide (HgO) decomposes on heating to give mercury (Hg) and oxygen (O2). It is a thermal decomposition reaction and the balanced equation can be written as: 2HgO(s)→heat2Hg(l)+O2(g)
What kind of reaction is this HgO → Hg O2?
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 O2 molar mass 32?
The molar mass of O2 is 32 gram per mole.
What is the formula for liquid mercury?
Mercury | Hg – PubChem.
What type of reaction is HgO → HgO 2?
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.
Can mercury be a liquid?
Is this balanced 2HgO → 2hg O2 *?
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.
Why is mercury liquid 12?
According to this configuration of mercury, we see that all the subshells are completely filled due to which it resists the removal of an electron. This makes mercury similar to noble gas elements. Therefore, mercury forms a very weak bond and exists as liquid in room temperature.
What type of reaction is HgO Hg o2?
What kinds of changes occur between atoms when substances undergo chemical reactions?
In a chemical reaction, bonds between atoms in the reactants are broken and the atoms rearrange and form new bonds to make the products.
