Will Sterling Silver tarnish if you are on Antobotics?
Silver tarnishing is a reaction of silver with oxygen to create silver oxide, silver's version of rust.Silver is antimicrobial, but the bacteria have nothing to do whatsoever with the silver tarnishing.So YES, silver will tarnish as long as it has contact with oxygen....and before someone chimes in, argentium sterling also tarnishes, just much more slowly.
Does plastic bottles go through a chemical change?
Yes, but very slowly ... that's what non-biodegradable is all about.
Is the spoiling of milk a chemical or physical change?
chemical change, of course. since there is an evolution of another substance, a change in odor, smell and the like.
What happens when silver chloride is exposed to light?
The color become grey because silver chloride (AgCl) is slowly decomposed to silver and chlorine.
When lead nitrate and potassium nitrate solutions are mix why is it changes colour immediately?
the colors will immediately change because it formed a chemical reaction. when two pure substances u know a reaction is going to occur by the temperature changing, change of color (why it turned yellow), produce of gas and produce of precipitation (when it slowly changed into a powder. not all of the have to occur but if u notice that one is that is when a chemical reactions is happening
Do silver and gold combine with oxygen?
Silver does, slowly (which is why it tarnishes). Gold for the most part doesn't (which is why it doesn't tarnish).It is possible to combine gold and oxygen, but it doesn't happen spontaneously at ordinary temperatures.

Why is a explosion a fast chemical change?
Because explosions don't happen slowly
Is cornflour and water a physical change?
Adding cornflour to water is a physical change. The reason this process is classified as such is that it does not change the chemical identities of the substances involved, which is the criterion for a process to be considered a chemical reaction. Technically, the cornflour would slowly hydrolyze in water, which would be a chemical reaction.
Is floating bubbles are example of chemical change?
no, not really, the reason the bubble floats is because of the hot air slowly moving upward. there are no chemical processes going on

Is tarnished silver still considered genuine silver?
== == Tarnish is in no way indicative of a low quality in sterling silver. Sterling silver (or .925 silver) is, by law, at least 92.5% pure silver and no more than 7.5% other metals. Sterling silver is an alloy, or mixture, of metals. Pure silver is too soft to be used for most jewelry and household good purposes, so other metals are added to strengthen the metal and make it more durable. Pure silver oxydizes (tarnishes) very slowly, but the addition of other metals to pure silver cause it to oxydize (or tarnish) more quickly. Laws regulate how metals must be marked. In the US, only pure silver can be marked ".999" and only silver of at least 92.5% purity can be marked ".925" or "sterling."
