Electrolysis is THE technique used to produce hydrogen that consists of “breaking” the … WebCO + H 2 O → CO 2 + H2. From Natural Gas. This remains the cheapest way to produce hydrogen on a commercial scale. The gas is heated to high temperatures (up to 1100 C) with steam and a Nickel catalyst. This results in the methane molecules breaking into Carbon Monoxide and Hydrogen. CH 4 + H 2 O→ CO + 3H 2.
Web13 mrt. 2024 · Hydrogen peroxide is made through the catalysis of the reaction of hydrogen (H2) with atmospheric oxygen (O2) to produce hydrogen peroxide (H2O2). The Step-by-Step Process Of Making Hydrogen Peroxide To put it in more complex terms, hydrogen peroxide is generally made according to this four-step process: WebOrganic Chemistry. Question #70552. Water can be decomposed into H2 and O2 via electrolysis. How many moles of H2 could theoretically be obtained from 87.5 g of water? Expert's answer. H 2 O = H 2 + ½ O 2. n (H 2 ) = n (H 2 O) = m (H 2 O)/M (H 2 O) = 87.5/18 = 4.86 (mol) Answer: 4.86mol of H 2 could theoretically be obtained from 87.5 g of water.
Web16 mrt. 2024 · Grey hydrogen is traditionally produced from methane (CH4), split with steam into CO2 – the main culprit for climate change – and H2, hydrogen.
