Given mass of tungsten, W = 415 g
Molar mass of tungsten, W = 183.85 g/mol
Calculating moles of tungsten from mass and molar mass:

<span>In order to covert a unit, you must know certain number of conversions. In here, the conversion is in unit of length. One meter is equal to 1000 meter. So if it is in cubic form, then the answer of one meter cube is also equal to 1000 cube. Then,
32 m</span>³ (1000 mm/1m)³
<span>or
</span>32 m³ (1000³ mm³/1 m³)
= 3.2 x 10¹⁰ mm³
Answer:
Sulfur dioxide is a covalent bond because we have two non-metals (Sulfur and Oxygen).
(<em>Sulfur dioxide formula)</em>
It's called Sulfur dioxide but it can be called Sulfurous anhydride and Sulfur (lV) oxide.
Sulfur dioxide can have different reactions:
-
In the presence of oxygen oxidation of sulfur dioxide to sulfur trioxide occurs and the formula is:

The equal is because it's a reversible equation. This reaction is spontaneous.
- The sulfur trioxide reacting with water produces sulfuric acid. The formula is:

- Also the sulfur dioxide reacting with sodium hydroxide produces sodium sulfite and the formula is:

- And finally we have the reduction of sulfur dioxide (it can be in presence of hydrogen sulfide) getting elemental sulfur and water. The formula is:
