Final Answer:
"The percentage atom economy when tungsten is produced through the reaction of tungsten oxide with hydrogen is 100%." is true
Step-by-step explanation:
Atom economy refers to the efficiency of a chemical reaction in utilizing atoms to form the desired product without generating any waste. When tungsten oxide reacts with hydrogen to produce tungsten metal, the reaction involves the direct conversion of tungsten oxide into tungsten without generating any byproducts or waste. This means that all the atoms from the tungsten oxide are incorporated into the final product, tungsten metal.
In this particular reaction, the conversion of tungsten oxide to tungsten metal involves the utilization of all the atoms present in tungsten oxide without any loss or generation of unwanted byproducts. Therefore, the atom economy for this reaction is 100%. The concept of atom economy is crucial in sustainable chemistry as it aims to minimize waste and maximize the utilization of resources, making processes more efficient and environmentally friendly. In this case, the complete conversion of tungsten oxide into tungsten represents an ideal scenario with a perfect atom economy.
