It is a
chemical decomposition
What type of reaction is h2 and O2?
An example of
a simple chemical reaction
is the breaking down of hydrogen peroxide molecules, each of which consists of two hydrogen atoms bonded to two oxygen atoms (H
2
O
2
).
What type of reaction is Hg O2 → HgO?
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
.
What type of reaction is the equation CO2 → C O2?
Another special type of
combination reaction
is a combustion, meaning a reaction in which something combines with oxygen and gives off heat and light: C + O2 → CO2 2 Mg + O2 → 2 MgO Combustion of a compound includes break-up (decomposition) of the compound first.
Is HG O2 a redox reaction?
The first reactions is a redox reaction because the
mercury is reduced
while the oxygen is oxidized. b.
Does H2 react with O2?
When molecular hydrogen (H
2
) and oxygen (O
2
) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen
peroxide
. … For both of the reactions shown, the hydrogen molecules are oxidized and the oxygen atoms are reduced.
Is 2HgO → 2Hg o2 a balanced equation?
Is 2H2 O2 2H2O balanced? Yes,
the equation is balanced
. There are the same number of Hydrogen (H) and Oxygen (O) atoms on both sides of the equation.
Is 2HgO 2Hg o2 a balanced equation?
Hg is a balanced element
because there is the same number of atoms of Hg 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.
Is C O2 CO2 a reversible reaction?
In a complete combustion reaction, fuel and oxygen are the reactants and the products are carbon dioxide and water. These two products cannot react to reform the fuel and oxygen, so
the reaction is irreversible
.
Is C O2 → CO2 a synthesis reaction?
Explanation: They are
both combustion and synthesis reactions
. Carbon, such as in the form of charcoal, which is mostly carbon, will react with oxygen to produce carbon dioxide.
What type of reaction is 2HgO → 2Hg O2?
In general,
decomposition reactions
occur when a solid compound is heated. This type of reaction almost always produces a gas. The following are examples of decomposition reactions: Heating mercury (II) oxide produces oxygen gas: 2HgO (s) → 2Hg (l) + O2 (g).
What is the formula of Hg?
Mercury
is a chemical element with the symbol Hg and atomic number 80.
