Why is Silicon dioxide insoluble in water?
silicon dioxide is an extended covalent network. Even amorphous SiO2 contains many atoms bonded together. They large covalent networks are too heavy to be maintained in soluti…on by hydrogen bonds with the water. (MORE)

Is silicone dioxide gluten free?
Being that it is basically sand or silica, I would have to say that it's a given that it is gluten free. Actually, this is a misspelling of silicon dioxide. Silicone is a comp…letely different substance. (MORE)

What is silicon dioxide soluble in?
The only chemical which effectively dissolves silicon dioxide is hydrofluoric acid. But note that silicon dioxide does dissolve to a very slight extent in water. The beaches a…re not dissolving away into the ocean, but some tiny amount of silicon dioxide is dissolving. (MORE)

What type of solid is silicon dioxide?
Also called common silica, it may exist in crystalline form as quartz, or as an amorphous solid (or supercooled liquid) called glass. Physically it is quite durable, hard and …resists high temperatures but exhibits a brittle fracture. Chemically it is covalently bonded, fairly inert, resists strong alkalis and most acids except Hydrofluoric Acid and only very very sparingly soluble in water. (MORE)

What is the answer to 20c plus 5 equals 5c plus 65?
20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4

What is the heat capacity of silicon dioxide?
Heat capacity is a function of temperature so there is no single value that is valid at all temperatures. That said, The heat capacity ranges from about 680 to about 730 J…/kg·K. If you just estimate it as 700 J/kg·K you won't be far off. (MORE)
