WATER
Water, a colorless liquid at room temperature, as made up of hydrogen and oxygen which are both gases at room temperature. When hydrogen gas reacts with oxygen ga, heat is given off and water is produced.

hydrogen gas + oxygen → WATER If we have 9g of water, 1g of it is hydrogen and 8g of it is oxygen. If we have 90g of water only 10g is hydrogen and 80g is oxygen. water decomposes when electric current is passed through it during electrolysis. —Preceding unsigned comment added by 117.102.56.70 (talk) 13:06, 5 December 2009 (UTC)
