Question

Вольфрам самый тугоплавкий металл (tпл = 3420 0С), который используют для изготовления нитей накаливания в электролампах. В промышленности его получают восстановлением из его оксида WO3 водородом. Составьте уравнение реакции.

Answer 1

WO3+3H2=W+3H2O, как вариант.

Answer 2

Уравнение реакции получения вольфрама в промышленности выглядит вот так: WO3 + 3H2 = W +  3H2O

Answer 3

Tungsten and its Properties

Tungsten is indeed the most refractory metal, with a melting point of approximately 3420°C. It is commonly used in the production of filament wires in incandescent light bulbs due to its high melting point and excellent electrical conductivity. In the industry, tungsten is obtained by reducing its oxide, WO3, with hydrogen gas. Let's now write the balanced chemical equation for this reaction.

Balanced Chemical Equation for the Reduction of Tungsten Oxide

The reduction of tungsten oxide (WO3) with hydrogen gas (H2) can be represented by the following balanced chemical equation:

WO3 + 3H2 → W + 3H2O

In this reaction, one molecule of tungsten oxide reacts with three molecules of hydrogen gas to produce one molecule of tungsten and three molecules of water.
