Silver is a white metal that is an excellent conductor. Silver tarnishes when exposed to air and light. The density of silver is 10.49 g/cm3. The melting point is 962oC and the boiling point is 2000oC. A chemical property of silver is A) density. B) melting point. C) tarnishes in air. D) that it is a conductor.

C) tarnishes in air.

Explanation:

Silver is a white metal that tarnishes when it is exposed to air that has the presence of sulphur gases. When exposed, it begins to undergo discoloration. It starts to darken as a result of the reaction with the gases causing the silver object to be disfigured. The commonest sulphur containing gas is hydrogen sulfide. As relative humidity goes up, silver can also tarnish faster.

conservation of mass

mass before something happens = mass afterwards

the answer is 100. i just did this lesson and got a 100% on it. : )
