Solids are defined by the following characteristics:
definite shape (rigid)
definite volume.
particles vibrate around fixed axes.
we are given the reaction Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag. This means for every mole Cu used, there are 2 moles of Ag produced. In this case, given 31.75 g Cu, converting to moles through molar mass and using stoichiometric ratio and the molar mass of Ag, the mass Ag produced is 107.9 grams.
Answer:
As we climb a mountain to a higher altitude, we experience a pressure increase. -True
The exception to the rule concerning the solubility of chlorides in water is PbCl2.
