How does H2 and O2 make H2O?
The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.
How do you combine O2 and H2?
In theory, it’s easy to make water from hydrogen gas and oxygen gas. Mix the two gases together, add a spark or sufficient heat to provide the activation energy to start the reaction, and presto—instant water.
When H2 reacts with O2 it is a dash reaction?
Explanation: Since 2 or more reactants combine to form a single product, proves that it is combination reaction.
How does oxygen and hydrogen make water?
A reaction between them requires energy to break the bonds between the atoms so they can form a new product. Once the bonds break, each hydrogen atom has a +1 positive charge, while each oxygen atom has a -2 negative charge. Two hydrogen atoms bound to one oxygen atom yield water, which is electrically neutral.
Is H2 O2 -> H2O balanced?
The equation is now balanced.
What temperature does hydrogen react with oxygen?
about 570 °C
Oxyhydrogen will combust when brought to its autoignition temperature. For the stoichiometric mixture, 2:1 hydrogen:oxygen, at normal atmospheric pressure, autoignition occurs at about 570 °C (1065 °F).
Why does oxygen react with hydrogen?
Hydrogen is a highly reactive fuel. Hydrogen molecules violently react with oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. But hydrogen does not react with oxygen at room temperature, a source of energy is needed to ignite the mixture.
When hydrogen reacts with oxygen write chemical equation for the above chemical reaction?
The reaction is represented by the equation : O2(g)+H2(g)→H2O(g).
Is H2 O2 combustion?
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.
Is H2 O2 -> h2o balanced?
Is H2 O2 exothermic?
The reaction between hydrogen and oxygen is exothermic- it releases energy to the surroundings: hydrogen + oxygen → water 2H2 + O2 → 2H2O Fuel cells use the reaction between a fuel and oxygen to produce electrical energy.
What is the balanced equation for H2O?
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.
What type of reaction is H2?
Reaction of hydrogen with air. Hydrogen is a colourless gas, H 2, that is lighter than air. Mixtures of hydrogen gas and air do not react unless ignited with a flame or spark, in which case the result is a fire or explosion with a characteristic reddish flame whose only products are water, H 2O. 2H 2(g) + O 2(g) → 2H 2O(l)
What is the balanced equation for CH4 plus O2?
Balance the reaction of CH4 + O2 = CO2 + H2O using this chemical equation balancer!
What is H O2?
OXYGEN H Type Cylinder – OX H. Oxygen (O2) which comprises 21 percent of the earth’s atmosphere, supports life and makes combustion possible.
