What is the balance equation of HgO?

What is the chemical reaction of 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 is balance equation formula?

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

What is the decomposition of HgO?

Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. Mercury(II) oxide is a red solid. When it is heated, it decomposes into mercury metal and oxygen gas.

How do you balance mg O2 MgO?

What is the balanced equation for the decomposition of mercuric oxide?

The decomposition of mercuric oxide (Hg)) on heating, resulting in the formation of mercury and oxygen, is represented by the following chemical equation- 2HgO+180kJ⟶2Hg+O2.

What is a balanced equation for the decomposition of water?

Water splitting is the chemical reaction in which water is broken down into oxygen and hydrogen: 2 H2O → 2 H2 + O.

What is the molar mass of HgO?

How do you balance a decomposition reaction?

You balance decomposition reactions just like any other reaction. Add coefficients in front of each formula so that the number of atoms of each element are the same on both sides, being careful not to change formulas by changing subscripts.

What is the balanced equation for CH4 O2 CO2 H2O?

How do you separate water equations?

What H2O 2?

The chemical formula of water is H2O. It is also called dihydrogen monoxide. The 2 is the subscript for H symbolises the presence of 2 Hydrogen atoms. Thus, we can say that there is hydrogen bonding in water. Therefore, water contains two hydrogen atoms and one oxygen.

What happens when CH4 reacts with O2?

When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is CH4(g) + O2(g) → CO2(g) + H2O(g) This type of reaction is referred to as a complete combustion reaction.

What is the stoichiometric factor between CH4 and H2O?

2.81g. Explanation: The coefficients in the balanced chemical equation can be used as the stoichiometric factor between CH4 and H2O. Molar mass converts between grams and moles. 1.25gCH4×1molCH4/16.043gCH4×2molH2O/1molCH4×18.015gH2O/1molH2O=2.81gH2O.

What is CH4 in chemistry?

Methane (CH4)

Methane is a colorless, odorless, flammable gas that is the simplest hydrocarbon and is the major constituent of natural gas.

What is the oxidizing agent in CH4 2O2?

CH 4 is a reducing agent, O 2 is an oxidizing agent.

What type of reaction is CH4 O2?

combustion
The combustion of methane or octane is exothermic; it releases energy. CH4 + 2 O2 → CO2 + 2 H2O + energy The energies of the products are lower than the energiies of the reactants.

What will be the enthalpy change for the following reaction CO2 2H2O CH4 2O2?

The enthalpy change for the reaction CH4(g) + 2O2(g) arrow CO2(g) + 2H2O(l) is -891 kJ/mol.

Is CH4 oxidized or reduced?

The most reduced form of carbon is CH4, the most oxidized is CO2.

Is CH4 a reducing agent?

In the combustion of methane molecular oxygen is the oxidizing agent and methane is the reducing agent.

What type of reaction is CH4 202?

CH4 + 2O2 → CO2 + 2H2O Incomplete combustion – carbon monoxide and water. Ex.

What is the reducing agent in CH4 2O2 → CO2 2H2O?

methane
In this given reaction the oxidising agent is oxygen because it oxidises methane to carbon dioxide and oxygen is reduced to water. Therefore, the reducing agent is methane.
