Every time you balance a chemical equation, you uphold the law of conservation of mass, which says that matter cannot be created nor destroyed. Take a basic balanced chemical equation: 2Na + Cl2 --> 2NaCl. That's the synthesis of salt from its constituent elements sodium and chlorine. Looking at the Periodic Table, the Atomic Mass of sodium is 23 and chlorine is 35. Two moles of sodium is 46, and diatomic chlorine is 70. That adds up to 116. Now look at salt. One sodium and one chlorine add up to 58. Double it because your molar coefficient is 2, and you get 116. 116=116, so this once again proves the law true.

∙ 9y agoThe conservation of mass states that matter cannot be created nor destroyed. In the equation of oxygen (O2) plus glucose (C6H12O6), the combustion reaction of metabolism, we see that all elements, by molar mass, are the same. In other words the atomic quantities on both sides (and the masses of each) of the reaction are conserved. C6H12O6 + 6O2 = 6C02 + 6H20. Thus, by conservation of mass all 6C, 6H, and 18O remain.

∙ 9y agoThe most common example that illustrates the law of conversation of mass is simply combustion. If something is burned completely, it seems as if all of the matter is gone or turned to ash. However, if you actually collected all of the gases expelled and ash left from combustion, you would find that it weighed exactly the same as the original mass being burned.

Is color a example of chemical property?
Color is a physical property.
Is transferring graphite from pencil to paper when writing a chemical or physical change?
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
