2013-04-20 · The reaction with hydrogen or carbon gas reduces to pure metal from tungsten trioxide. 2 WO 3 + 3 C + heat → 2 W + 3 CO 2. WO 3 + 3 H 2 + heat → W + 3 H 2 O. Tungsten (VI) oxide occurs in nature in the hydrates form, which consists of minerals: tungstite WO 3 ·H 2 O, meymacite WO 3 ·2H 2 O and hydrotungstite. Conclusion for the formula of tungsten oxide

What is the % yield of of a reaction in which 42.00g of tungsten(VI)oxide (WO3) reacts with excess hydrogen gas to produce metalic tungsten and 2.40mL of water. (assume the density of water is 1.00g/mL) Chemical equation of H reacting with tungsten oxide - 11783132 Tungsten(VI) oxide reacts with hydrogen to produce tungsten metal and water. What is the percent yield for the reaction if 4.00 g of tungsten (VI) oxide yield 2.80 g of tungsten metal. A) Write the balanced equation. WO3+3H2--->3H2O+W is the balanced equation. B) calculate the theoretical yield of 2016-10-25 · As you look at the balanced equation, you can see that one mole of tungsten(VI) oxide reacts three moles of hydrogen to produce one mole of tungsten and three moles of water. The mass of one mole of tungsten is 183.8 grams.
