Staining specimen with heavy metal salts (e.g. tungsten, molybdenum) allows you to see the specimen better with higher contrast when electron beam deflects off of your sample.
Answer:
0.159 \%
Explanation:
The acid will dissociate according to the reaction shown below:-
Given that, pH=3.8
The concentration of can be determined from the expression fo pH as:-
pH = - log ![[H^+]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D)
3.8 = - log
= 
The initial concentration of RCOOH was 0.10 M, then the percent dissociation was- calculated as shown below:-
Substance P replaces X in the compound XY
this is the characteristic of decomposition reaction
When water turns to steam,
D) the water absorbs energy which causes the water molecules to have more kinetic and potential energy changing their configuration from a liquid to a gas.
