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.
Is 2H2 plus O2 equals 2H2O plus heat endothermic or exothermic?
exothermic
2h2o 2h2 plus o2?
Water can be broken down to oxygen and hydrogen and hydrogen can be ignited in oxygen to form water. 2H2O --> 2H2 + O2 (takes energy) 2H2 + O2 --> 2H2O (releases energy)
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
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.
