Answer: the answer is 26, I have the same course
Explanation:
Answer: increase pressure and decrease temperature.
Explanation:
Increasing pressure uses force to make the gas molecules come closer together. (Decreasing pressure allows the molecules to spread out) Decreasing temperature will also cause the molecules of gas to come together closer. (Heat excites molecules causing them to spread out and therefore expand)
Answer:
Al is oxidized while Ag is reduced.
Explanation:
The complete molecular equation is;
3Ag2S + 2Al --> 6Ag + Al2S3
Oxidation half equation;
2Al ------> 2Al^3+ + 6e
Reduction half equation;
6Ag^+ + 6e -------> 6Ag
Overall redox reaction equation;
2Al + 6Ag^+ ----->2Al^3+ + 6Ag
Hence; Al is oxidized while Ag is reduced.
Answer:
Ductility
Explanation:
Ductility is the ability of a metal to be converted into a thin wire without getting break and loosing its hardness. The property of Ductility of a metal allows us to make a wider use of them. Some most ductile metals are gold, silver, copper etc. whereas some of the metals with very less ductility are tungsten, steel and other alloys as they are very hard to transform into a thin wire.
A metal with less ductility can be malleable as it can have the ability to be converted into a thin sheet. Not all the metals are ductile but some of them have high ductility, some have less and some of them are non ductile.
