Volcanic ash is magnetic because the ash has iron in in the objects the lava/magma burns. Or the ash already has iron from the mantle of the Earth burning into the magma of the core.
Water H20, Carbon Dioxide (CO2) and ash (potassium salts etc).
The answer is: salt is soluble in water.
it all turns in to ashes or it disintergrates
The magnesium burns readily in air to produce a white ash which is magnesium oxide. This is due to the "oxidation" of the metal.
ASH,
When oil shale burns it produces high quantities of ash, and is usually taken to large ash heaps!
It turns into ash and smoke.
it burns and then turns to ash
It dissipates into the air as smoke and whatever it burns either melts or turns into ash

Ash Wednesday
it turns into ash

ash and *gas *I'm not sure at all
Anthracite, as long as it has low ash and sulfur content
That is true. Coal is composed mostly of carbon, and when it burns it turns into carbon dioxide, which is a gas. The ash is just a minor residue of the non-carbon part of the coal. Whereas, magnesium when it burns turns into a solid material, magnesium oxide; it gains oxygen from the air and therefore increases in weight.
