Question

H2O--->H2+O2 helppppp​

Answer 1

Ответ:

2H₂O (t°C) → 2H₂↑ + O₂↑ - это реакция разложения

Answer 2

It looks like you're trying to represent a chemical reaction where water (H2O) is broken down into hydrogen gas (H2) and oxygen gas (O2). The chemical equation for this reaction is:

2H2O → 2H2 + O2

In this reaction, two molecules of water (H2O) are converted into two molecules of hydrogen gas (H2) and one molecule of oxygen gas (O2).

Keep in mind that this is a simplified representation of the reaction, and in reality, breaking down water into hydrogen and oxygen requires energy input, such as through electrolysis or other processes. If you need more information or have any other questions, feel free to ask!
