Physical: The chemist could try to bend it to find out how malleable it is. He could also try to pull it into wires to find out how ductile it is.
Chemical: The chemist could put the metal into contact with other substances to get an idea of how reactive it is, and he could try to burn it and find out how flammable it is.
The coefficients of H2S and HNO3 in the balanced reaction equation are 2 and 3 respectively.
<h3>Chemical reaction</h3>
In a chemical reaction, reactans interact in a unique way to form products. In this case, the unbalanced reaction equation is; H2S + HNO3-----> NO + H2O.
Since this reaction is redox and electrons are lost/gained in the process, the coefficients of H2S and HNO3 in the balanced reaction equation are 2 and 3 respectively.

Answer:
An excellent experiment is to heat sodium thiosulfate in a water bath. The solid crystals will dissolve into the water in the hydrated crystals forming a supersaturated solution. ... Placing a small crystal in the supersaturated solution will cause the liquid to turn solid.
