What else can I help you with?
Which is more reactive platunium copper or silver?
Silver is more reactive than copper and platinum. Silver tarnishes easily when exposed to air, while copper only reacts slowly with air over time. Platinum is the least reactive of the three metals and remains largely unaffected by air and water.
Is burning a candle happen slowly and a chemical change?
Burning a candle is a chemical change that happens relatively quickly. The heat from the flame melts the wax, which is then vaporized and reacts with oxygen in the air to produce light, heat, carbon dioxide, and water vapor. This process is a combustion reaction, which is a type of chemical change.
Does plastic bottles go through a chemical change?
Plastic bottles do not undergo a chemical change when used as intended, such as holding water or other liquids. However, when plastic bottles are recycled and melted down to form new products, this process involves a chemical change.
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.
Is the spoiling of milk a chemical or physical change?
The spoiling of milk is a chemical change. This is because the bacteria in the milk breaks down the proteins and fats in the milk, leading to a change in its chemical composition and properties. It cannot be reversed by physical means such as cooling or filtering.
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.
Which is more reactive platunium copper or silver?
Silver is more reactive than copper and platinum. Silver tarnishes easily when exposed to air, while copper only reacts slowly with air over time. Platinum is the least reactive of the three metals and remains largely unaffected by air and water.
What slowly change earth crust?
Weathering, chemical change, and mechanical change. I hope i could help.
Why is a explosion a fast chemical change?
Because explosions don't happen slowly
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
What is the color of praseodymium?
that doesn't exist nor is that a word Actually, Praseodymium is an element on the periodic table of elements. There for a word. And to answer the question, Praseodymium is a silver-white color.

Other chemical changes occur very slowly such as the formation of?
Other chemical changes that occur very slowly include the rusting of iron and the decomposition of organic matter in the soil. These processes can take years or even decades to fully manifest due to the slow rate of reactions involved.
Does plastic bottles go through a chemical change?

Do evolution change quickly or slowly?
Slowly.
Do populations change quickly or slowly?
slowly
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."
