Compounds of silicon and hydrogen, known as silanes, react explosively with oxygen and react with water, forming silicon dioxide and water and silicon dioxide and hydrogen gas respectively. Silicon accounts for 28 percen... More »

The solubility of silicon dioxide, SiO2, in water depends on a number of different factors, including pressure, temperature and the structure of its surface. Generally speaking, silicon dioxide is virtually insoluble in ... More »

All alkali metals and most alkaline earth metals react with cold water. The alkali metals are lithium, sodium, potassium, rubidium and cesium. The alkaline earth metals that react with water are magnesium, calcium, stron... More »

A burning candle is an example of a chemical change because the paraffin wax, which is a hydrocarbon, undergoes a chemical reaction with oxygen to form water and carbon dioxide gas. Because the chemical structure of the ... More »

Nonpolar molecules include hydrogen and oxygen gas, methane and gasoline. Alkynes are also considered nonpolar. Generally, nonpolar compounds are considered water insoluble and do not dissolve in water. More »

Uncoated lithium metal reacts with water to form a colorless lithium hydroxide solution and hydrogen gas. The resulting solution is basic because of the resulting hydroxide ions. The reaction is both spontaneous and exot... More »

Mentos makes soda fizz due to the Mentos breaking the bonds in water molecules and encouraging the growth of more carbon dioxide gas, which is used to carbonate sodas. This is due to a combination of a rough surface area... More »
