What kind of chemical relation is shown 2H2 plus O2 equals 2H2O?
A balanced chemical reaction.
What type of reaction is 2H2O 2H2 plus O2?
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
What is the balanced equation for C2 H2 plus H2 equals C2 H6?
The balanced chemical equation for the reaction C2H2 + H2 → C2H6 is: C2H2 + 2H2 → C2H6
Is 2H2 plus O2 equals 2H2O plus heat endothermic or exothermic?
exothermic
What type of reaction is hydrogen plus oxygen equals water?
The reaction between hydrogen and oxygen to form water is a synthesis reaction. It is also a combustion reaction since it involves a chemical reaction of a fuel (hydrogen) with an oxidant (oxygen) to produce water and release energy in the form of heat.

What is the balanced chemical equation of o plus h equals h2o?
2H2 + O2 --> 2H2O
What is the balanced reaction for C plus H2CH4?
C+ 2H2--> CH4 is the balanced equation.
Is the formula 2h2 plus o2 balanced or unbalanced?
The formula 2H2 + O2 is unbalanced. It represents the reaction of hydrogen gas with oxygen gas to form water (H2O). To balance the equation, it should be written as 2H2 + O2 → 2H2O.
What is the equation for hydrogen plus hydrogen?
Hydrogen is naturally H2 so when you combine two H2 molecules, you will get 2H2. It won't be H4 as it will only exist in pairs, not fours. If you are combining H + H, you will get H2 So either: H+H → H2 Or H2 + H2 → 2H2
Which of the equations below is an example of a thermochemical equation a Mg plus 2H3O plus plus Cl- --- Mg2 plus plus 2Cl- plus H2 plus h20 b 2H2 G plus 2O2 G ----H2O g plus 483.6kj c 2H2 G plus 2O2?
The equation c) 2H2 (g) + O2 (g) → 2H2O (g) is an example of a thermochemical equation because it shows the reactants and products with energy change included, but it doesn't explicitly mention the heat added or released during the reaction.
What is h2 plus o2 plus equals h20?
The chemical equation h2 + o2 -> h2o represents the reaction between hydrogen gas and oxygen gas to produce water. This reaction is a combustion reaction where hydrogen and oxygen combine to form water in a highly exothermic reaction, releasing energy in the form of heat and light.
