The reaction between a HC (hydrocarbon) and O (oxygen) to produce CO2 (carbon dioxide) and H2O (water) is a standard form of a combustion reaction. Therefore,the correct answer would be A. Methane will burn forming C02 gas and H20 gas.
Is CH4 2O2 → CO2 2H2O a combination reaction?
In this demonstration methane gas or natural gas is the hydrocarbon that reacts with oxygen as shown below: CH4 + 2O2 → CO2 + 2H2O There are two types of combustion reactions: complete and incomplete combustion. The products are always carbon dioxide and water.
What type of reaction is CH4 2 O2 → CO2 2 H2O?
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.
Is CH4 O2 — CO2 2H2O a balanced equation?
To balance the hydrogen atoms, put a 2 in front of H2O: CH4 + O2 CO2 + 2H2O. The oxygen atoms can be balanced by putting a 2 in front of the O2 on the left: CH4 + 2O2 CO2 + 2H2O. The equation is now balanced.
Is CH4 2O2 CO2 2H2O a balanced equation?
Use coefficients to balance equations • CH4 + 2O2 > CO2 + 2H2O • C=1, H=4, O=4 > C=1, H= 4, O=4 • Equation is now balanced!
What is reduced in the reaction below CH4 O2 → CO2 H2O?
CO2 + 2H20. In this reaction in the reactant side the carbon is losing hydrogen to form carbon dioxide.So here the carbon is oxidised and also oxygen is gaining hydrogen and getting reduced. …
What is the balanced equation for HgO Hg O2?
Search by reactants (HgO) and by products (Hg, O 2)
|1||HgO → O2 + Hg|
|2||H2O2 + HgO → H2O + O2 + Hg|
What is the balanced equation of N2 H2 NH3?
o The new chemical equation is N2 +H2 →2 NH3 Reactants Products Nitrogen 2 2 Hydrogen 2 6 Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3.
Which chemical equation is unbalanced?
If the numbers of each type of atom are different on the two sides of a chemical equation, then the equation is unbalanced, and it cannot correctly describe what happens during the reaction.
How do you balance a chemical equation?
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.
Why is there a 2 placed in front of ammonia?
First, by placing a two in front of ammonia, the nitrogens are balanced. This leaves 6 moles of atomic hydrogen in the products and only two moles in the reactants. A coefficient of 3 is then placed in front of the hydrogen to give a fully balanced reaction.
How many oxygen atoms are needed to produce 2 H2O?
2 oxygen atoms
Is H2 O2 a combustion reaction?
A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. The combustion of hydrogen gas produces water vapor. 2H2(g)+O2(g)→2H2O(g) Notice that this reaction also qualifies as a combination reaction.
What happens when you mix H2 and O2?
When molecular hydrogen (H2) and oxygen (O2) 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. In this oxidation, a molecule of hydrogen gas is ionized to two electrons and two protons.
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.
How do you identify a combustion reaction?
Good signs that you’re dealing with a combustion reaction include the presence of oxygen as a reactant and carbon dioxide, water, and heat as products. Inorganic combustion reactions might not form all of those products but remain recognizable by the reaction of oxygen.
What are the two types of combustion?
Here’s a closer look at five types of combustion:
- Complete Combustion. Complete combustion requires a combination of fuel and oxygen.
- Incomplete Combustion. Incomplete combustion occurs when there is not enough oxygen for the fuel to fully react.
- Rapid Combustion.
- Spontaneous Combustion.
- Explosive Combustion.
What are some real life examples of combustion reactions?
Combustion Reaction Examples
- Burning wood. Burning wood in a fire is an example of a combustion reaction.
- A Lighted match. A lighted match is another example of a combustion reaction.
- Burning coal. Burning coal qualifies as a combustion reaction because coal transforms from a solid element to a vapor during the process.
What is the generic equation for a combustion reaction?
The generic equation for a combustion reaction is AB + O2 à AO + BO where AB is a compound or molecule that is mixed with the oxygen and AO and BO are chemical compounds or molecules known as oxides (since they are elements that are bonded to oxygen).
What are 5 examples of combustion in everyday life?
What are five examples of combustion in your everyday life?
- Burning of Wood or Coal for the household purposes.
- Burning of Petrol or Diesel for using vehicles like car.
- Combustion of Natural Gas or LPG to cook.
- For the production of energy in thermal power plants.
What is the example of combination reaction?
Combination Reactions For example barium metal and fluorine gas will combine in a highly exothermic reaction to form the salt barium fluoride: Another example is given by magnesium oxide combining with carbon dioxide: Often, reaction can fall into more than one category.
Which reaction type best describes H2O SO3 → H2SO4?
This is also an example of a reaction that is exothermic. Heat is released as the reaction proceeds. Sulfur trioxide (SO3) gas reacts with water (H2O) to form sulfuric acid (H2SO4).
What type of reaction is H2SO4?
Even dilute sulfuric acid reacts with many metals via a single displacement reaction as with other typical acids, producing hydrogen gas and salts (the metal sulfate). It attacks reactive metals (metals at positions above copper in the reactivity series) such as iron, aluminium, zinc, manganese, magnesium, and nickel.
