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 »

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 »

Test for carbon dioxide by burning a splint, using litmus or indicator papers or running the gas through lime water. Additionally, according to the National Institutes of Health, a blood test can be performed to determin... More »

Chemical differentiation describes the process by which heavier, molten elements like iron and nickel sank to the center of the Earth and lighter elements like silicon, oxygen and aluminum populated the surface of the pl... More »
