Hydrogen and oxygen are two elements that combine to form water (H2O) through a process called electrolysis. However, you can't "make" water by simply combining hydrogen and oxygen, as they are already present in water molecules. Here's a brief overview of the process: • Electrolysis: Hydrogen gas (H2) is produced at the cathode (negative electrode) and oxygen gas (O2) is produced at the anode (positive electrode) when an electric current is passed through water or an electrolyte. • Hydr...
