All metals corrode under the right conditions only some more easily then others. as it turn out the metals that corrode most easily are usually also the most abundant.
Of course coins corrode. Over time coins corrode. They corrode faster in tap water. Bleach also corrodes coins. If you have time, try some experiments and see what substances corrode coins.
Acids (including dilute acids such as vinegar) are reducers- they will corrode metals. Vinegar may cause accelerated corrosion while (due to high water content) also oxidising (rusting) metals which are prone to oxidation. To accelerate the oxidation of metals, you require a stronger oxidising agent. However, using a dilute acid may enhance the oxidation process in metals which galvanise. Some metals do not 'rust' as they develop a protective oxide layer when exposed to oxidising agents, or metal parts which can rust may contain or be coated with such a metal - types of steel, for instance. An acid may corrode the galvanising layer or metal, allowing the more vulnerable metal to continue oxidation.
There are some polymers which are stretchy while the others are not because of the disordered structure. Elasticity refers to the ability of a polymer to stretch past its original length.
Because they are cleaner or because of the type of metal they are made of.
Some chemical properties of metals are that they have good electrical and thermal conductivity. Metal also form positive ions or cations and ionic bonds. When exposed to air and moisture, many metals tend to corrode.
Corrosion of metal is caused by oxygen or oxidising substances, salty water and some medium strong acids
because some have metal
Some properties of metal include good conductors of electricity and a shiny appearance. Some are very sturdy while others are very malleable.
Because some chemicals can react with metals and corrode the drums.
some are bendier than others, while some are more ductile(they can be rolled into a long wire.)
which reacts with some metals causing it to break down.
Yes. Some can only corrode soft things, and some can corrode everything. But in short, all acids can corrode something. It only gets dangerous if the acid can corrode you.
Of course coins corrode. Over time coins corrode. They corrode faster in tap water. Bleach also corrodes coins. If you have time, try some experiments and see what substances corrode coins.
It depends on the metal - some metals are resistance to corrosion. Iron, when subjected to water and air, will rust quite quickly, at least on the surface. Stainless steel will not be subject to corrosion. Silver will tarnish and appear blacker. Gold will remain golden and never corrode. Copper will corrode and become rather greenish.
They used to, prior to the early 90s. Some people believe they still do, while others - myself included - believe they no longer do.
A washing machine is basically made of an alloy that does not corrode easily. Stainless steel is found in some. This is Iron witch also contain Nickel and Chromium. Some manufacturers use high quality stainless steel in their washing machines. This metal has got a higher content of Chromium and make it even more resistant to corrosion. In many cases, this metal is acid proof too. The box however is mostly made out of the cheapest metal possible, and this does corrode easily when the paint or galvanization comes off.
