Formation of wolfram disilicide, WSi2.
umm it reacts violently in water. so it may be "soluble" but it reacts rather violently
SiO2 + 2Ca --> 2CaO + Si
578 kJ are released
E
nothing
it produces a gas
Silicon reacts with fluorine
Si+CO2 ---------> SiC+SiO2
Tungsten, otherwise known as wolfram, is a metal used in alloys and jewelry. It's pH neutral, and reacts very little to bases.

Normally, elements react with oxygen to form their oxides. The chemical formula for the oxide of silica is SiO2. It is a very common compound on earth.
SiO2 + 2Ca --> 2CaO + Si
578 kJ are released
eddy happens
bcoz that sun shines is so shines that happens to the silicon layers in a solar cell
Sodium Sillicate, well known for its "crystal garden" experiment.
It changes chemically.
