Direction: Identify the law in chemical bonding described in the following statements
1. Methane is always 75% carbon and 25% hydrogen.
2. When 10.0 grams of H2O dissociates, the combined masses of hydrogen and oxygen gases is 10.0 grams.
3. Oxides of nitrogen exist in two forms: nitrogen monoxide (NO) and nitrogen dioxide (NO2 )
4. A pure sodium chloride (NaCl) sample obtained in Manila has the same composition as that of a pure sample from Cebu City.
5.Sulfur dioxide (SO2) can be further oxidized to form sulfur trioxide (SO3).
6.Twelve grams of carbon reacts with four grams of hydrogen to form a gram of methane (CH4)
7. The ratio of the masses of oxygen per mass of 1 sulfur atom in SO2 and SO3 is 2:3.
8. The methane produced from the flatulence of cows and the methane in your gas tanks has the same smell.
9. A can of corned beef which weighs 250 g is processed by placing 200 g corned beef in a 50 g tin can. 10. Hot tea and iced tea taste the same.
