Index fossils can help geologists compare rock Layers at Distance locations.
Index fossils help identify where Unconformities may have occurred.
Then that layer can be Compared to other locations.
The class of organic compound is most likely to be used in anesthetics is ethers. The first ether that is used in anesthetics is diethyl ether .
In general anesthetic works on brain, and produce unconsciousness and insensitivity to feel pain or anything. Generally it lowers the sensitivity of the organs. Diethyl ether is the first ether that is used as anesthetics.
Because if you have a liquid then you need a glass to keep it together and when it is a solid it is already together so you don't need to do anything
Well in this
case, silver
nitrate is reduced:
Ag<span>+ </span><span>+ </span>e<span>− </span>→ Ag(s) ↓
Meanwhile, the aluminum
is oxidized forming a positive ion:
Al(s<span>) → </span>Al<span>3+ </span><span>+ 3</span>e−
To get the
overall reaction, we add the half
equations so that the electrons are eliminated:
Al(s<span>) + 3</span>Ag<span>+ </span><span>→ </span>Al<span>3+ </span><span>+ 3</span>Ag(s)
And similarly:
Al(s<span>) + 3</span>AgNO3(aq<span>) → </span>Al(NO3)3(aq<span>) + 3</span>Ag(s<span>)</span>
Chemical change? Need more context.
